  Regenstein Center for Bionic Medicine: Intuitive Control of Bionic Limbs

  (Georgia Institute of Technology, 2024-04-10) Hargrove, Levi

  Amputation is a leading cause of disability, and prosthetic devices are commonly accepted treatment options to restore functional capabilities. However, current prosthetic devices still cannot fully match the functionality of their natural counterparts. This talk focuses on the progress made in the development and control of bionic limbs for individuals with limb loss. The first portion of the talk provides an overview of the development, testing and commercialization of pattern recognition control systems for prosthetic arms, including their operation with advanced surgical techniques, such as targeted muscle reinnervation. A significant emphasis of this work has been on evaluation based on real user feedback, ensuring that the developed technologies meet the actual needs and preferences of end users. The second portion focuses on the application of these approaches (ie statistical pattern recognition and finite state-machines) to controlling powered leg prostheses. Finally, I will discuss our recent work in using deep-learning coupled with benchmark datasets (some collected at Georgia Tech) to remove the reliance of finite-state machines from our overall control approach.

  A symbiotic philosophy for bio-inspired robotics

  (Georgia Institute of Technology, 2024-03-27) Moore, Talia

  Humans have frequently looked to natural phenomena to inspire the design of art, structures, and mechanisms. However, there are as many different ways to learn from nature as there are words for this approach: bioinspiration, biomimicry, and biodesign to name a few. In this talk, I propose a taxonomy for categorizing distinct biodesign approaches and use examples from my own research to illustrate the methodology and benefits of each. In particular, I introduce the field of Animal-Robot Interactions and describe how bio-inspired approaches can be used to further biological inquiry while advancing robotics.

  INTRODUCING strauss: A FLEXIBLE SONIFICATION PYTHON PACKAGE

  (Georgia Institute of Technology, 2023-06) Trayford, James W. ; Harrison, Chris M.

  We introduce strauss (Sonification Tools and Resources for Analysis Using Sound Synthesis) a modular, self-contained and flexible Python sonification package, operating in a free and open source (FOSS) capacity. strauss is intended to be a flexible tool suitable for both scientific data exploration and analysis as well as for producing sonifications that are suitable for public outreach and artistic contexts. We explain the motivations behind strauss, and how these lead to our design choices. We also describe the basic code structure and concepts. We then present output sonification examples, specifically: (1) multiple representations of univariate data (i.e., single data series) for data exploration; (2) how multi-variate data can be mapped onto sound to help interpret how those data variables are related and; (3) a full spatial audio example for immersive Virtual Reality. We summarise, alluding to some of the future functionality as strauss development accelerates.

  Critical AI literacy with children: in pursuit of fair and inclusive technology futures

  (Georgia Institute of Technology, 2024-03-14) Sharma, Sumita

  Children interact with Artificial intelligence (AI) in various direct and indirect ways, yet, there is limited research on the impacts of AI on children. Further, these studies mainly focus on cultivating, nurturing, and nudging children towards technology use and design, without promoting critical perspectives towards AI. For intance, there is little discussion with children on the limitations, inherent biases, and lack of diversity in current design and development of AI, and on critical examination of the ethical aspects of technology use, design, inherent limitations, and consequences of these on children and society at large. In this talk, I will present my work on critical AI literacy with young children, sharing lessons from hands-on workshops with children in Finland, India, and Japan.

  Foley Scholar Winner and Finalists Presentations Spring 2024

  (Georgia Institute of Technology, 2024-03-07) Bhat, Karthik Seetharama ; Narechania, Arpit ; Pendse, Sachin ; Riggs, Alexandra Teixeira

  Foley Scholar Award Winner: Envisioning Technology-Mediated Futures of Care Work, Karthik Seetharama Bhat. Caregiving is a universal activity that is receiving increasing attention among technologists and researchers in the wake of the COVID-19 pandemic. Emerging technologies like conversational AI, augmented and virtual reality, and smart homes have all been described as potentially revolutionary technologies in care work, intended to automate and transform the overall care experience for caregivers and care recipients. However, such promises have yet to translate to successful deployments as these technological innovations come up against socioculturally situated traditions of care work that prioritize human connection and interaction. In this talk, I will share empirical studies looking into how formal care workers (in clinical settings) and informal care workers (in home settings) reconcile technology utilization in care work with sociocultural expectations and norms that dissuade them. I will then discuss possible technology-mediated futures of care work by positing how emerging technologies could best be designed for and integrated into activities of care in ways that unburden care workers while ensuring quality care.

  From State Space Control to Intelligent Machines: A Five-Decade Journey in Mechanical Systems Control

  (Georgia Institute of Technology, 2024-03-06) Tomizuka, Masayoshi

  Masayoshi Tomizuka joined the Mechanical Engineering Department of UC Berkeley in 1974 after obtaining a PhD from MIT in the same year. It was an exciting time for someone in the field of dynamic systems and control. The 1960’s – 1970’s was the period when the state space control theories blossomed such as maximum principle, dynamic programming, Lyapunov stability, Kalman filtering, Linear Quadratic Gaussian Control and stability based adaptive control theory. At the same time, computer/information technology has made phenomenal advances during the period. At MIT Tomizuka used IBM1130 (with a card reader and printer) and a PDP-8 mini-computer. When he joined UC Berkeley, the campus mainframe computer was a CDC (Control Data Corporation) 6000 series computer, and the lab computer was PDP-7, which was upgraded to PDP-11, LSI-11, etc. The control program at Berkeley covered from both theory to implementation, and it was followed by many other schools. The1970’s was the time when a new generation of mechanical systems showed up; IBM introduced the Winchester Hard Disk Drive in 1973 and the FANUC Corporation was established in 1972. Tomizuka's laboratory, Mechanical Systems Control (MSC) Laboratory, naturally evolved to a group to study both mathematical and implementation aspects of controls. The current research emphasis of the MSC Laboratory is on intelligent industrial robots and autonomous driving. Several representative current projects will be introduced.

  Increasing Awareness of Human Biases during Visual Data Analysis using Visual and Haptic Feedback

  (Georgia Institute of Technology, 2024-02-08) Narechania, Arpit ; Paden, Jamal ; Endert, Alex

  Human biases impact the way people analyze data and make decisions. Women denied C-suite promotions (gender bias), ailing but younger people denied optimal treatment (age bias), dark-skinned people denied parole (racial bias), etc. are examples of biases rampant in the world. Visual data analysis tools such as Tableau and Excel help users see and understand their data but do not report potential biases exhibited by users (e.g., an overemphasis on the Age attribute). Existing research tools have explored visual means (e.g., highlighting the Age attribute to appear darker than other attributes) to increase users' awareness about (biased) analytic behaviors. We believe that using a single, "visual" modality to present such information is a passive type of guidance that only burdens the user's perception skills, which are already engaged to perform the analysis task. We investigate how a more active type of guidance, a combination of "visual" and "haptic" modalities, can better guide the user. We present a visual data analysis system, wired to a haptic gaming mouse. This enhanced system tracks a user's interactions with data and presents them back via haptic feedback (e.g., "buzz"es or vibrates the mouse whenever bias is detected). Through an exploratory user study, we find that these dual guidance modalities can sometimes actively stimulate and engage the user's attention, making them more aware of their analytic behaviors. However, we also find that the haptic feedback can also distract the user, informing the design of future multimodal guidance-enriched user interfaces.
