Integrated Modeling of the Battlespace Environment
Found in: Computing in Science and Engineering
By Tim Campbell, Richard Allard, Ruth Preller, Lucy Smedstad, Alan Wallcraft, Sue Chen, Hao Jin, Saša Gaberšek, Richard Hodur, Joseph Reich
Issue Date:September 2010
pp. 36-45
The goal of the Battlespace Environments Institute (BEI) is to integrate Earth and space modeling capabilities into a seamless, whole-Earth common modeling infrastructure that facilitates interservice development of multiple, mission-specific environmental...
SqueezeBlock: using virtual springs in mobile devices for eyes-free interaction
Found in: Proceedings of the 23nd annual ACM symposium on User interface software and technology (UIST '10)
By Jeffrey R. Hightower, Shwetak N. Patel, Sidhant Gupta, Tim Campbell
Issue Date:October 2010
pp. 101-104
Haptic feedback provides an additional interaction channel when auditory and visual feedback may not be appropriate. We present a novel haptic feedback system that changes its elasticity to convey information for eyes-free interaction. SqueezeBlock is an e...
WATTR: a method for self-powered wireless sensing of water activity in the home
Found in: Proceedings of the 12th ACM international conference on Ubiquitous computing (Ubicomp '10)
By Eric Larson, Gabe Cohn, Jon Froehlich, Ramses Alcaide, Shwetak N. Patel, Tim Campbell
Issue Date:September 2010
pp. 169-172
We present WATTR, a novel self-powered water activity sensor that utilizes residential water pressure impulses as both a powering and sensing source. Consisting of a power harvesting circuit, piezoelectric sensor, ultra-low-power 16-bit microcontroller, 16...
HydroSense: infrastructure-mediated single-point sensing of whole-home water activity
Found in: Proceedings of the 11th international conference on Ubiquitous computing (Ubicomp '09)
By Conor Haggerty, Eric Larson, James Fogarty, Jon E. Froehlich, Shwetak N. Patel, Tim Campbell
Issue Date:September 2009
pp. 235-244
Recent work has examined infrastructure-mediated sensing as a practical, low-cost, and unobtrusive approach to sensing human activity in the physical world. This approach is based on the idea that human activities (e.g., running a dishwasher, turning on a ...
