Issue Date:September 2013
pp. 583-586
Mobile and embedded electronics are pervasive in today's environment. As such, it is necessary to have a natural and intuitive way for users to indicate the intent to connect to these devices from a distance. We present DopLink, an ultrasonic-based device ...
     
AirWave: non-contact haptic feedback using air vortex rings
Found in: Proceedings of the 2013 ACM international joint conference on Pervasive and ubiquitous computing (UbiComp '13)
By Dan Morris, Desney Tan, Shwetak N. Patel, Sidhant Gupta
Issue Date:September 2013
pp. 419-428
Input modalities such as speech and gesture allow users to interact with computers without holding or touching a physical device, thus enabling at-a-distance interaction. It remains an open problem, however, to incorporate haptic feedback into such interac...
     
uTouch: sensing touch gestures on unmodified LCDs
Found in: Proceedings of the SIGCHI Conference on Human Factors in Computing Systems (CHI '13)
By Gabe A. Cohn, Ke-Yu Chen, Shwetak N. Patel, Sidhant Gupta
Issue Date:April 2013
pp. 2581-2584
Current solutions for enabling touch interaction on existing non-touch LCD screens require adding additional sensors to the interaction surface. We present uTouch, a system that detects and classifies touches and hovers without any modification to the disp...
     
An ultra-low-power human body motion sensor using static electric field sensing
Found in: Proceedings of the 2012 ACM Conference on Ubiquitous Computing (UbiComp '12)
By Dan Morris, Desney S. Tan, Gabe Cohn, Joshua R. Smith, Matthew S. Reynolds, Shwetak N. Patel, Sidhant Gupta, Tien-Jui Lee
Issue Date:September 2012
pp. 99-102
Wearable sensor systems have been used in the ubiquitous computing community and elsewhere for applications such as activity and gesture recognition, health and wellness monitoring, and elder care. Although the power consumption of accelerometers has alrea...
     
LightWave: using compact fluorescent lights as sensors
Found in: Proceedings of the 13th international conference on Ubiquitous computing (UbiComp '11)
By Ke-Yu Chen, Matthew S. Reynolds, Shwetak N. Patel, Sidhant Gupta
Issue Date:September 2011
pp. 65-74
In this paper, we describe LightWave, a sensing approach that turns ordinary compact fluorescent light (CFL) bulbs into sensors of human proximity. Unmodified CFL bulbs are shown to be sensitive proximity transducers when they are illuminated. This approac...
