Perception in Hand-Worn Haptics: Placement, Simultaneous Stimuli, and Vibration Motor Comparisons

(Georgia Institute of Technology, 2015) Seim, Caitlyn ; Hallam, James ; Raghu, Shashank ; Le, Tri-An ; Bishop, Greg ; Starner, Thad

Glove-based tactile interfaces are used for augmented reality, rehabilitation, teaching, and consumer electronics control. Yet questions remain regarding perception of tactile stimuli on the hands. In an effort to inform the design of such tactile interfaces, we investigate participants' abilities to sense vibration on the hands. First, we examine the effect of stimulus location on recognition accuracy. Ventral (palm-side) placement on the fingers is critical: accuracy increases with proximity to the palm, linearly, on all fingers. Second, we study perception of multiple simultaneous vibrations on the fingers. Recognition degrades with increasing number of simultaneous tactile stimuli and no subitizing is found. Error is >60-80\% for more than two simultaneous stimuli points. Our third study compares the perception of Eccentric Rotating Mass (ERM) and Linear Resonant Actuator (LRA) vibration motors. Recognition accuracy was less using LRA motors, especially in placements on the palm side of the fingers (-20.3% versus -10.1% for ERM). Correct recognition of chords was also less or comparable using LRA motors, suggesting that the ERM motor is preferable.
Can I Wash It? : The Effect of Washing Conductive Materials Used in Making Textile Based Wearable Electronic Interfaces

(Georgia Institute of Technology, 2013) Zeagler, Clint ; Gilliland, Scott ; Audy, Stephen ; Starner, Thad

In this paper we explore the wash-ability of conductive materials commonly use in creating traces and touch sensors in wearable electronic textile systems. We performed a wash test measuring change in resistivity of conductive traces constructed using different combinations of conductive materials after each wash cycle.

Recognizing Sign Language from Brain Imaging

(Georgia Institute of Technology, 2009) Mehta, Nishant A. ; Starner, Thad ; Jackson, Melody Moore ; Babalola, Karolyn O. ; James, George Andrew

The problem of classifying complex motor activities from brain imaging is relatively new territory within the fields of neuroscience and brain-computer interfaces. We report positive sign language classification results using a tournament of pairwise support vector machine classifiers for a set of 6 executed signs and also for a set of 6 imagined signs. For a set of 3 contrasted pairs of signs, executed sign and imagined sign classification accuracies were highly significant at 96.7% and 73.3% respectively. Multiclass classification results also were highly significant at 66.7% for executed sign and 50% for imagined sign. These results lay the groundwork for a brain-computer interface based on imagined sign language, with the potential to enable communication in the nearly 200,000 individuals that develop progressive muscular diseases each year.
Localization and 3D Reconstruction of Urban Scenes Using GPS

(Georgia Institute of Technology, 2008) Kim, Kihwan ; Summet, Jay ; Starner, Thad ; Ashbrook, Daniel ; Kapade, Mrunal ; Essa, Irfan

Using off-the-shelf Global Positioning System (GPS) units, we reconstruct buildings in 3D by exploiting the reduction in signal to noise ratio (SNR) that occurs when the buildings obstruct the line-of-sight between the moving units and the orbiting satellites. We measure the size and height of skyscrapers as well as automatically constructing a density map representing the location of multiple buildings in an urban landscape. If deployed on a large scale, via a cellular service provider’s GPS-enabled mobile phones or GPS-tracked delivery vehicles, the system could provide an inexpensive means of continuously creating and updating 3D maps of urban environments.
The Use of Different Technologies During a Medical Interview: Effects on Perceived Quality of Care

(Georgia Institute of Technology, 2007-10) Caldwell, Britt ; DeBlasio, Julia M. ; Jacko, Julie A. ; Kintz, Erin ; Lyons, Kent ; Mauney, Lisa M. ; Starner, Thad ; Walker, Bruce N.

This two-phase study examines a physician’s use of one of five different types of technology to note a patient’s symptoms during the medical interview. In this between-subjects design, 342 undergraduates viewed one of several videos that demonstrated one condition of the doctor/patient interaction. After viewing the interaction, each participant completed a series of questionnaires that evaluated their general satisfaction with the quality of care demonstrated in the medical interview. A main effect of technology condition was present in both phases. Further, in Phase 2 we found that drawing the participant’s attention to the type of technology used has a divergent effect on their general satisfaction with the doctor/patient interaction depending on the technology condition. These findings have implications for healthcare providers such as how to address technology and which type of technology to use.

Reading on the Go: An Evaluation of Three Mobile Display Technologies

(Georgia Institute of Technology, 2006) Vadas, Kristin ; Lyons, Kenton Michael ; Ashbrook, Daniel ; Yi, Ji Soo ; Starner, Thad ; Jacko, Julie A.

As mobile technology becomes a more integral part of our everyday lives, understanding the impact of different displays on perceived ease of use and overall performance is becoming increasingly important. In this paper, we evaluate three mobile displays: the MicroOptical SV-3, the Sony Librie, and the OQO Model 01. These displays each use different underlying technologies and offer unique features which could impact mobile use. The OQO is a hand-held device that utilizes a traditional transflective liquid crystal display (LCD). The MicroOptical SV-3 is a head-mounted display that uses a miniature LCD and offers hands free use. Finally, the Librie uses a novel, low power reflective electronic ink technology. We present a controlled 15-participant evaluation to assess the effectiveness of using these displays for reading while in motion.
