Just real quick, I'm going to give the usual reminder. Obviously, I am neither Keith nor Richard. We've really got the B team out today. Both of them had personal things to attend to, but everyone should remember. Please do make sure to clean up after yourselves and make sure you silence anything that's going to make noises. I already managed to catch my laptop making noise, so it happens to all of us. Today's talk is going to be really fun and exciting. I'm sure I don't have to introduce Rosa to anyone here, but she leads the Ubc Health and Wellness Lab currently and does fascinating research. And so you're here to listen to her talk, not me. So I will let her go ahead and get started. Yeah. So thank you so much. You know, there were a couple of e mails that came in. You know, this and that. Rose. I'm like, It's okay. I require no introduction. There you go. I'll make myself at home Today, I'm going to talk to you about forms of accountability at theater section of science and design implications from ecologies of care studies and PTSD and diabetes. Um, first of all, I'm going to give you a general introduction to my research and in the area of health and wellness. I'm going to argue that computing systems can address fundamental problems in chronic care management. I teach HTC one this semester and I've decided that I'm optimistic, despite everything else that all of the critical theories tell me I should be thinking about. But really, this presentation is an opportunity to discuss the role that accountability plays in conducting research at the intersection of science and design. I'm going to talk to you about some of the theories that drive my accountability. Then I'm going to talk about lessons I've learned over these past 15 years in HCI and future work. But first, my title is pretty convoluted. Can I see a show of hands for people that understood why my presentation title is so convoluted? At least one person that took HTC one, maybe my title is really homage to Bill Gaver, who wrote a chapter in this really great book that's called Ways of Knowing an HCI. In there he talks about science and design and the implications of different forms of accountability. And he defines accountability as expectations of what must be defended. And the way that these narratives in science and design are form and how they drive our endeavor. In this chapter, he characterizes what makes science and design different based on the activities that are essential for each. Now he also says, look, we could talk about all the things that are the same about science and design, right? They're both empirical disciplines. Or rather, if we think about HCI and computer science as examples. But he really argues that when we focus on the similarity, it really obscures the very features that give each endeavor its specificity and potency. He emphasizes that science and design each has its own logic, motivation, and values. And that if we were going to put these kind of families of activities together, then we'd say that science uncovers what exists, and design creates the new. And his chapter is really nice. I urge you to read it and maybe we'll have a conversation afterwards. The first half is basically drawing these differences between science and design. The second half is him explaining what his type of design is. And I will cover that much more lightly, but it really this understanding that what it is that we do really drive against that accountability. I discussed a little more. After all, I guess this would be the positionality part of the talk, where I tell you that, you know, why am I so fascinated with this chapter? And so, I don't know if you'll be able to see it, but the idea was that Gabor and I share an origin story, right? So, in this chapter he goes on to say, and it's an e mail, I actually had the courage to write him and say that, that I was going to give this talk and really talk about his paper. But really, you know, we shared the same origin story. He was a cognitive neuroscientists that moved into design. I was a cognitive neuroscientist that moved into design. I thought about, you know, these implications for the kind of work that we do. And he was very nice and I made his day. And once again, it's always good to put yourself out there because if nothing else, you can add it to your talk. All right? So my training, as I mentioned, in experimental psychology, right? We study human thought, perception and behavior. Of course, science is a method of choice where we make observations, we make predictions, we test these predictions, we develop interventions to improve the human conditions. Then we use these theories to drive our research. And I'm going to define theories as a set of principles that organize our observations and also propose predictions. And so, you know, Gabor would say, well, of course, rosa science and the way that you've just described, it has this epidemiological accountability science is really concerned about how knowledge is established, right? How do you know what you claim to know? It's really concerned and driven by this kind of process, how rigorous the process is, how rational the process is. Really, if you compare it to design, this notion of something being interesting or impactful is not necessarily definitional. Gabor goes on to say that progress in science is either inductive or hypothesis driven. And of course, when you think of science, you think it has to be replicable. There has to be objective, it has to be generalizable. You have to move towards establishing or expanding on scientific theory. But then I moved into HCI research here, right? This discipline studies how people interact with computers. But at some level we're really designing systems that are useful, usable, and enjoyable, that allow others to meet their goal. The idea is a human centered computing. We take it a little further to say, well actually it's not just about the human and the machine, it really is about how these computational artifacts affect and transform the human experience and culture. And that loop of us also transforming the technology. If I think about the method that I use most, I'm going to talk about a user centered design approach where I'm trying to understand the context by doing needs assessment, design ideation, prototyping, evaluation. I'm talking to people that know all of this so you don't have to take my course courts, but you can if you want in HCI. Our contributions are pragmatic and futuristic, right? We come up with novel interactions, with novel interfaces, with novel systems, but also we generate ideas. We start to talk about what are those design implications, What are those design guidelines? And here again, Gabor would say, where we just talked about the kind of epistemological accountability that's inherent in science. When we have design, we have this aesthetic accountability, right? It's going to have to be based this question of does it work? Central design is really based on the problem solving production value and the ability to integrate function form, material culture motion. Again, entire socio technical experience. And we're going to say that design is successful, right? When it validates new methods, it drives conceptual perspective. But again, the methodology is not lockstep the way it is in science, and it's not critical whether for how it's going to make or break the design. Then Gabor goes on to say that progress is driven by the ability to meet the context, right? So, does it work by the ability to create and constrain these novel design spaces? But whereas in science we talked about generalizability, replicability, objectivity, in design, we're going to have different values. We're going to be driven by how it meets the individual, how it resonates with the context, how evocative it is, how illuminating it is. Where does science and design meet me in the health and wellness research I do and the artifacts I build. Because for me, the artifacts I build have to be useful and usable. But they also have to be general, replicable and objectively efficacious. If I'm going to build something for somebody that has asthma, diabetes, or PTSD, at the end of the day, I want to know that it's actually going to improve this condition for me. It means that I can't just leave it at the design, but I'm going to have to deploy it. We talk about intersectionality and why it's critical in health research. Currently in the US, health spending is about 70% of the gross domestic product. It's going to be about a fifth. It's a huge problem. Of course, it's not just about the money. About 7.10 deaths in the US are attributable to chronic illness. What does it mean that I do this work at the intersection of science of design? Well, it means that I build computational systems because they provide a way to scale human effort over time and space, right? If I talk to a psychologist or a pomonologistorpodiatrist, they can meet one person at a time. But really with the systems I build, we can reach many people. Again, the other thing, the other place where I bring my science to bear is really in using the psychological theories and concepts to conduct HCI research. Again, when, if the premises that humans, her computing can improve the human condition. Then for me at some point I have to have evidence from both science and design. Again, it must be, it must be useful. It must be engaging. And I have to be able to show you, right, that I can improve health and wellness outcomes. So what I'm going to do in the rest of the talk is really give you kind of three examples of how I've done this in my work. I will give you the, the most mature research which is the work that I did in pediatric asthma. And by the way, that's right when I was moving from science to design. And so of course, I was going to do a random control trial. I'm going to tell you about the work that I'm doing now and post traumatic stress disorder. Tell you a little bit about how that design really informs what I do. Then I'm going to tell you about the newest work that I'm doing in diabetes, All right? I've told you that chronic conditions are such a big problem. If we think about what these chronic conditions have in mind, we're going to have these major gaps. First is engagement. How is it that we can get the user to act in a way that's going to improve their health? How is it that we can use the current treatments and practices and really build technology in a way that supports the user? In chronic conditions like diabetes, like asthma, people see their Dr. three or four times a year, but there's never any data about what happened between those visits. You've all had the experience. You go to the Dr. and the Dr. says, how are you? And you say fine, even though you had this killer migraine three weeks ago, you just can't remember. Again, one of the things that I want to do with my technology is I want to understand what happens between a visit for the provider. Where the provider can be, again, it can be a physician, the therapist, a podiatrist. Then once you're at the point of care, how do we mediate communication? What would the provider want to know? What would you want to tell the provider? How do we drive self advocacy through our system? Again, over the past 50 years, I've really designed systems to support a variety of stakeholders. Not just the individuals that might have a given condition, but their families and professionals that care for them. Again, I use ubiquitous interfaces because that's how we know that they can actually work in the real world. Central to all of this is that collaboration with domain experts are key, right? That is, I need to understand what the gold standard of care is, what's the science. Then I need to understand on the design part, how will I make sure that what I build works? I've had a great time here in Atlanta. I've been able to work with Children's Health Care of Atlanta, for example, looking at AR education games in the emergency room. I've worked a lot with Emory Hospital, They continue to be really great colleagues and now friends. After these 15 years, I've also had the great pleasure of working with the CDC. One of our crews in our lab is that we designed the first CBC milestone tracking app. For the first version, there were over 700,000 downloads in the first three or four years. But again, I tell you about my collaborations and I tell you about the methods I use. But really at the intersection of science and design for me is moving beyond those traditional user centered design approaches to using and leveraging different theories. And I'm going to talk to you today about the health belief model and also the ecological systems theory. We talk about a chronic disorder. How are we going to operationalize it? Well, it has to last more than one year, and it has to lead to limitations in function, activity, or social role. There's some dependency on medicine, the required education, beyond what's expected of an age. This is exactly what happens in pediatric asthma. Again, looking at that arc from going all the way from science and design in a mature manner, I'm going to tell you about that work. As you might know, asthma is characterized by inflammation of the airways that narrows them and makes it hard to breathe. It's the most common pediatric disorder in the world. If I want to know how do we improve health outcomes in children with asthma, what technology might we use? Well, I think even now text messaging was the most popular way to that individuals in 13 to 17 age range communicated. If I was going to have to pick a method to say that I can improve a health outcome, right? You know, what would I do? How would I build it here? We use theory to drive the intervention features. And then if I wanted to be able to make that scientific claim about a causal relationship between the system I deployed and children's health outcomes, then I'd have to use a random control tile. And so this is the work that I did with using the health belief model, and it really is what variables can be used in behavior change intervention. And here we have, again, back to my bias trained as a cognitive neuroscientists. This idea that these beliefs are central in the way that we act in the world. The idea was that we were going to take some of these modifying factors like knowledge about asthma, we were going to t test this hypothesis about symptoms, right? The idea is that if you don't think you're sick enough, why would you take your meds? And so the idea was that we were going to try to send out these messages that would get people to think about their condition. Can text based intervention, using these health belief model features improve health outcomes? Right? So is it useful? Can we prove it? Will patients engage with the system between medical appointments? Right? Is it usable? Basically, we had a very like the little system that could kids would either get a symptom question. In the past four weeks, did you wake up at night wheezing and coughing, or they get both a symptom question and a knowledge question. The knowledge question would just send out a little query. Everyone's asthma is the same, true or false. And then depending on how the kid responded, we would give them a little factoid about asthma. This was done in a randomized control protocol over a three month period. Again, in children have moderate severe asthma, either Dr. three or four times a year. And that's when we met them. Then we wanted to, of course, help the physician at the point of care. And so we visualize the text responses. The doctors had access to the dashboard, right? It allowed for data driven follow up in between care, so they'd get pinged. If the kids response showed that they had gone over to the red side, that is that they might be at risk for an asthma exacerbation. We also had all of the responses related to their asthma knowledge and symptoms and the idea that this would prompt that point of care interaction. When we did this study where we looked at children that were 13 to 17, we found that the symptom and knowledge that if a kid got a text message a day right, they actually had statistically significant improvement in lung function. All they were doing was responding to text, and yet this, their improvement in lung function, it caused their improvement in quality of life. One of the things that we found was that this was the case when we worked with children that had private insurance. Most HDI researchers would have said, great it works. But again, those scientific battling for me came back in the way of understanding, Can we replicate result? Can we extend the result? For example, we had done a symptom only condition. But what if we did a knowledge only condition? But also what are those conceptual factors? Will the system actually work with different demographic groups? Once again, that premise that we can improve the human condition, that good science can drive health equity. For me, it was understanding, does it generalize to other demographic contexts. We know that asthma disproportionately affects poor individuals. We know that black children are five times more likely to die from asthma than their white counterparts. And so we did the series of studies and children that were low SES is they had private, pardon me, they had public insurance. And so we knew that they lived in a household that had limited funds. We found that we were able to replicate the results. Is that when in my favorite title for a paper, that in fact the text message today does keep the pulmonologists away for children that have public insurance. Importantly, we that when we had these children. Um, that had public insurance, they would have improved lung function, even when we send a text message every other day. Again, back to the scientific accountability, the patient's lung function improved in a statistically significant manner. So the system was useful, right? This brings up Gabe's notion of definiteness, that we know that something is precise and quantifiable. Then there was also the design accountability. The system was useful. Patients were willing to give us information over an extended period of time. All right, now I'm going to talk to you about my ongoing research in post traumatic stress disorder. Here, this is much less mature work. We're in what Gabriel might call the productive indiscipline, right, where we're not bound to doing these lockstep experimental studies that are going to give us some definitive answer. Here I'm going to talk to you about the ecological systems theory. This is the developmental psychological theory. I've used it to think about how can technology be situated in an individual's life. The ecological system theory was proposed by Uri Bronfenbrenner and he defined development, right, change through time and how the individual interacts with people in different settings and the degree to which the individual can alter those interactions. And one of the first papers I wrote when I came to HCI was really thinking about how can we go from this typical social science, complicated understanding how can we flatten it so that can be used to understand the role of technology design in children that had asthma. This was my students early on. What I say is that the power in using this theory is that it really defines the setting that envelops the individual, right? It reminds the designer about the user's entire ecosystem. Again, the set of principles that are going to really put us in a lockstep manner to understand the context. And then that this ecological approach can help us understand where to target technology. Over the course of those ten years, we did a lot of studies that we're really trying to figure out. Not technology for children with asthma, but those that were for the child and the family in the community. Again, one of the things about these theories is that they are generalizable. And we were able to use this ecological systems approach to study adults with post traumatic stress disorder. Ptsd is a trauma and stressor related disorder characterized by trauma re, experiencing by avoidance of trauma related situations, by negative alteration in mood and negative arousal. We focused on veterans because about 20% of veterans of the Iraq and Afghanistan conflict meet diagnostic criteria for. And then you know that I'm in design because I have a quote, right? I'm left with basically nothing to trap in war, to be at peace, to damage, to be at war. Once again, I want to start from the premise of what is the gold standard of care. I'm not going to say, what can I build in this amorphous space, but I'm really going to constrain it. The gold standard of care for PTSD treatment is prolonged exposure therapy. Right here, clinicians teach individuals to gradually approach their trauma related memories, feelings, and situations. One of the things that they do during therapy is they train veterans, or they train patients really on how to quantify their stress. This subjected unit of distress is really important. They train these individuals on understanding how their stress level is changing. One might be no stress and 100 is inca, incapacitating. What happens during a PE therapy? Well, there's a clinical session, you have the traditional talk therapy, where the patient is going to voice the narrative of the traumatic event. Right? They're going to voice this imaginal narrative again, because what they're trying to do is get the patients to understand that their fears are unfounded. They're going to ask them to do homework. One homework is basically listen to yourself narrating This imaginal narrative. The other one is actually confronting these stress provoking stimuli in the real world. They call these in vivo. I'm going to show you an example of an imaginal narrative. This is a mock narrative, it's not one that is real, but rather that curated from many conditions. We've heard in this particular narrative, something very terrible happens to, to a person. They basically are trying to escape from attack. They end up harming a lot of children. And again, this feeling that they could have done something. But the main idea that I want you to get from this is that you have the narrative. And then there's the homework. So the homework would be, go home and listen to this for a half an hour or until your subjective distress dropped to about half. And then the other part is going to be every day, right, on Monday, you're going to go to sit in the park with a friend. You're going to be there for 30 min or until your stress decreases. Or you're going to go to the park by yourself or you're going to sit at the park and eventually you're going to be at the park on Saturday afternoon when all the kids are out there. The good news is that it's the gold standard of care and recovery is very high. The bad news is that it's very hard to actually deliver it. Some of the trouble is that it relies on patient self support. Right? So far, there had been this inability to collect objective information during and between those clinical visits. It relies on clinical intuition. Did they go to the park, stay there for 30 min? Were they engaged? There's limited decision support tools that promote guidance of proper therapy, practice and reflection towards recovery. Then that because we don't have this information, there aren't ways to understand how to improve the therapy and improve the delivery. We were very excited to get an NSF award in Smart and Connected health, where we were trying to build a computational solution to improve the delivery of PE and the patient practice during PE therapy. The idea that we were going to innovate here, we were going to build a ubiquitous system to collect the data during the PE therapy. We were going to build these human centered interfaces that we're going to allow it to be useful and usable to both clinicians and patients. And then that Thomas was going to be able to work his magic and it was going to allow us to predict how these clinical factors might affect individual recovery. Here, right, we have this classic opportunity for design. Ga says there's this fashioning something new that works in the world. And here we can see that the theory, right, so the science is really driving the design that we work with here. We're using the ecological systems theory to both create and constrain new artifacts. So there are these proposals of what we might build. These proposals, according to Gabor, are going to lead to progressively more focused design explorations. There really are these conversations with materials. What methods are we going to use? Once again, we're free from having to do these lockstep scientific experiments. In fact, since we got the award, we've been able to study veterans ecologies of care. Trying to understand what are some of those barriers that veterans experience. What do they think? What do their civilian counterpart and families and friends think would do the clinicians? Then from there, we can talk about what are the design implications of these results? What tools do they need? Right? We found that they wanted to be able to provide feedback about engagement with clinicians. They wanted to be able to collect data from outside their clinical session. And they wanted to build a way of understanding how others might be able to inform the therapy. We were able to build and try to understand what we had initially called this kind of social sensing or social scape. And through another series of studies that had different phases, again a very different methodology. Clinicians trusted others, and veterans were presented with the storyboard about what a social sensing or an informant system might look like. From there, we were able to get these design guidelines that emphasize the familiar. People want to emphasize the familiar in the positive when they give feedback. But when they receive feedback, veterans want to control who actually gets to provide the feedback. But there's also the need to understand how it's providing the feedback actually. Affecting these relationships. And then there's the logistics. How do we customize the cadence of the feedback that the trusted others are giving? When we think about the kind of work that we do and the selection bias that we might have when we have people that are willing to be in our studies, right? This really drives different sets of questions. Working with GOA, we were able to look at, trying to get a broader understanding of what's going on, really. We looked at the PTSD or rather the veteran sub red, to try to understand what is it that veterans actually want. We ask them about PE. But if we actually analyze the veteran sub red, they actually care more about health finance, family, and navigating the governmental support. Again, how do we provide the right structure for veterans to get the care they need? But again, eventually, right for my type of research, I want to be able to quantify precisely what it is that we gain by, by building the system. And the third aim of our proposal is to do just that. To understand the various data types we collect. Right? Eventually what the machine will do is we take the subjected unit of distress and what we try to understand is eventually, can we predict the units of distress? Then how do we give those machines that feedback to be able to understand, perhaps not just the individual, um, recovery, but how the program is working in general or rather within this particular segment of veterans. But also how do we improve these care models? One of the things we found in the colleges of paper is one of the common reasons people drop out is because our veterans drop out is because they find that they don't have a good match with their clinicians. Then the question is, can we do that? We have our system, our interfaces and we hope to deploy them this next semester. All right. I've told you about the arc of being able to do random control trials and the the pediatric betting. I've told you about how my work progress within PTFE in the last four years of research, and I want to tell you a little bit about what I'm doing now. I'm working in the area of diabetes and in particular, fouls. Once again, this is an incredibly important area. As you might know, about 10% of adults are diagnosed with diabetes and 1.3 are pre, diabetic, diabetic fools. This terrible complication that we can't as scientists get our arms around, for example, the mortality rate after a person has an amputation is about 70% Within five years of having an amputation, we have people perish. Of course, this is in underserved communities, both African American and Hispanic. And we started with the numbers just for context, this is basically $100,000,000,000 problem. About a third of diabetes expenditure is in diabetic foot Al. All right, then what am I going to do? Well, our goal in the next year is to basically understand the goal ten gold standard of care for diabetic foot Al. This is a full foot exam. Traditionally, podiatrists will measure the skin, they'll measure the blood circulation, they'll measure sensation, and they'll measure the soundness of the musculoskeletal frame. And we are in fact building a app to do that. I want to thank we were lucky enough to get the Emery I humanity grant and we've seen ten of the 200 people that we were going to get data from. All right, well what does the diabetic ulcer computational system look like? Well, no surprise. Right, So far we're really thinking about how do we build a system for the patient. How do we bring together what we're calling foot soldiers? Right. People that will help them collect the data or the video data. We're thinking about what are the algorithmic implications. Most of the work in photography and images is on white skin, right? One of the things we're trying to build is the biggest database of different skin colors. Then, because we've learned so much about being able to move beyond the people that come to our studies. How can we learn about people's practices in Read It and Twitter again? Right. We're going to be able to leverage what we got from Pe to be able to collect the data for this study. So just to recap, I've given you examples of my research at the intersection of science and design. I've told you about the work that I've done in asthma, and I've been able to prove that there's a causal relationship between children getting text messages and their improvement in lung function. I've told you a little bit about the prolonged exposure, continuing sensing system, and I hope to show that it actually leads to more efficacious therapy. I've introduced you to the newest research area, which is a diabetic foot alters. Stay tuned. I'm going to just take a couple of minutes to reflect on what I've learned from using theory to influence technology design. So that intersection of science and design first, when you use the theory, right, I say that the resulting systems are inherently generalizable. I told you about the work we did in asthma, but we were also able to use the text messaging system for children with diabetes. We were able to use the same system looking at congenital heart disease, again, in this iterative framework. We've learned a lot. We learned that when it's children facing some negative outcome years from now, the awareness is important and it'll get them to drive behavior. However, when we were looking at adults, these are people that are 40 that are faced with these symptoms. It actually made them more anxious and not any more likely to take their me Again, these studies are really important to understanding the context of when these systems work. I've told you and I've shown you how the resulting design implications, what it means to do, work with children that have asthma, what it means to work with individuals that have PTSD, and how this ecological approach is transferable. Then that we can use these context to study things that we wouldn't have thought about before dime. My student that graduated last year was able to look at PPE, the ecology around building this artifact in the wild. Other lessons I've learned from this intersectional approach is that for me, the ecological systems theory really broadens the definition of what a caregiver is, right? In autism work that I didn't describe, we were able to use crowd sourcing to build these interventions and so we could get the community to provide care. Then you saw that I was showing you or sharing with you some of the red data and that allows us to better understand how to care for veterans. In conclusion, I've shown you that computing can alleviate the negative impacts of chronic disorders. I've shown you that health research requires accountability at the intersection of science and design. My goal, and this is again, the beauty about doing this empirical work, is that you can choose to live in either the design space or in the science space. But for me, in order to show that my systems work, I have to have that accountability to science. But again, in order to do good science, I need to show that my systems are going to be useful and usable. I hope that one takeaway is that the future is ripe with opportunities for HCI to improve patient engagement, continuity of care, and point of care interaction. Thank you very much. All right, I'm happy to take any questions. Yes, Mike. I'm just trying to find them here. Yes, this was work that was carried out and this was all the grad student leg work, TJ. Basically, they started taking that design approach. They started going to informational sessions about asthma. And in these sessions they met nurses. With these nurses were able to find a clinic that was actually interested in helping them understand how to improve their system of workflow. Again, give and take that you need to build a community. At that point, we were reading different kinds of theories and we really thought about this idea that in some of the interviews that the students did, one of the things that kept coming up is that children and also adults that have asthma or COPD won't understand that they have symptoms, right? The doctors will say, people will be talking like this because they can't breathe and they'll be like, I have no problem, right? This idea that symptom awareness is really critical really drove this desire to say, what if we were able to raise their awareness about their symptoms. Right? And again, we had the pulmonologist came up with, you know, with the symptom questions as you saw back to the way that you write and you do this work. There was legal ease, so we say in the past four weeks, right? Because we didn't want to be accountable if somebody is going to have an asthma attack, right? So GT Legal had to make sure that the questions or these prompts were going to be appropriate. And so it was really just this idea that we wanted to look at these two conditions, right? My personal experience, I know that I could probably only have one cookie, but I'm going to choose to have more knowledge isn't enough to moderate our behavior. But the question was, if we did that combination right, initially, when you do basic science, you want to throw in the kitchen sink. And so we had a symptom only condition, right? And then we had a knowledge condition to see what happened. And so it was really working with this model and trying to understand how do we derive those symptom questions. Yes, yes, yeah, yeah, that's a great question. Which is, you know, was it the symptom? And the interesting answer was that about half of the kids said yes, oh my goodness, I am sick, I better take my med. And there was about another 40 or 30% that said I'm going to get my text messages anyway, I'm going to use it as a reminder to take my med, right? So the idea that through the two different measures, right, one was driven by symptom, the other one was driven by just utility of the SMS. We did have this improvement. Again, the important thing, we always say that the statistics gives us the what, right, and the interviews gives us the why. It was this interesting thing. But again, I think the relevant part is because we had done a randomized control trial. Because kids were randomly assigned to one thing or the other, right? That we did have the soundness of the rationale and then that we were able to show that we could get improved outcomes in children that had diabetes. And that was also a random control trial? Yes, there was a control group that got nothing right. So we had a we had a group that was assigned to symptom on another group that was assigned to symptom and knowledge, and then a control group and then we also had a group that was the knowledge only. Right. Yes, yeah, yeah, yeah. So again, I, you know, I'm drawn to cognitive models because that was my training. But you can imagine that other people might be, you know, people in Europe are still very, very inclined. It could be that people could use other types of models. I use cognitive behavior models because those are the ones that appeal most to me. That's how I grew up. Intellectually. Yes. Yes. At feel, right. Yeah. Right. Again. And this is where, you know, if I had been in a behavioral science department, then I would have. And I wanted to know, cross all those IRB hurdles to figure out how many people are getting their prescription refilled, right? How many people are. So to your point, definitely we could have looked at that. But there were constraints of, you know, not being in that space and we do our best, right? All right. So yes, yeah, So I really, I mean, one of my personal philosophy is that unless I've already given something to the community, I can't ask for it. So I told you that one of the reasons that we were appealing to the clinical group is because they wanted to understand their workflow, right? And so we did this study, we were able to give them something then they felt comfortable enough that they were going to get something from us. There was that the author, I think, of our asthma publications and all of the other publications have stakeholders in them, right? The other thing is we start early, right now we're trying to do work with this diabetic in a community housing. Well, this semester and next semester we are doing tech help, where we go out on Thursday and we're saying if anybody needs any tech help, we're here to help you. Eventually, we're going to ask if anybody wants to be in, in our diabetic foot studies, but that's not going to be everybody. So how can we give something to the community? We're building in that sense, we're building these relationships. Mhc, right? The MS, HCI students are going out to basically to help when they can, but also to get an understanding of the landscape. Yeah, yes, yes, yeah, yeah, yeah. When we were trying to merge or really to understand how could we flatten this idea of the macrosystem and the exosystem and the mesosystem, right? This idea that we have added to the ideologies of a culture, this question of how can you get at that, that's been a question that drove a lot of the work that I've done in autism, understanding what are different communities values and thoughts about technology for autism. And so, you know, you can say, well you can go to meet, for example, veterans. But in fact, it's incredibly hard back to the point that you made earlier. It's incredibly hard to meet some of these communities. And so really read it gave us this great opportunity, I'm going to find it somewhere, but read it gave us this great opportunity to understand, you know, what veterans actually wanted, right? Because back to thinking about these methods, we always think, well, it's their self selection, there's self selection, there's the Hawthorne effect, et cetera, et cetera. But in some sense, when we go to read it, sure it's self selection because it's the people that go there. But on the other hand, it's giving us an understanding of what these people care about. If we're trying to represent what they want and what they need. The good way of doing that intrusively and when it comes up making sure that the text that the actual read it posts don't come out so that we can keep the anonymity. But hopefully, again, at some point, be able to build something that's actually useful to them. All right. Yes, yeah, yeah, yeah. I hope one idea is that I've always thought that if we have more data, then of course always qualified, right? That more data makes better systems. But we have to have the representation because especially just thinking about this. Now when we think about the images or we think about doing these computer vision stuff, there's no data, there's not enough data on people that don't have just white skin. I think that to me it just reiterates this idea that we need to make sure that we're getting representative datasets. For me, I think I'm just constantly reminded how do we get representative data sets? Back to the question of how do we start to triangulate on what veterans want. Of course, it applies to machine learning, but it also generally applies to, I think good data science in general. Yeah. Well, I don't want to keep you. You've been very generous with your time. Anything else? All right. Thank you.
