Monday, March 29, 2010. Whack Gestures: Inexact and Inatentive Interaction with Mobile Devices. Scott E. Hudson. Beverly L. Harrison. Human-Computer Interaction Institute Carnegie Mellon University, Pittsburgh, PA 15213. Intel Labs Seattle, WA 98105. Whacks by themselves are hard to distinguish from bumps, so to minimize false positives a pair of whacks was used to frame a gesture as follows. The three gestures used for evaluation:. Whack as a signal gesture. Shaking as a signal gesture. The need for ges...

Thursday, January 28, 2010. 3DM: A Three Dimensional Modeler Using a Head-Mounted Display. Jeff Butterworth, Andrew Davidson, Stephen Hench and T. Marc Olano. The notion to develop an easily accessible 3D modeler using VR in the early 90’s was very forward thinking. In many regards this same goal in a simplified non VR version was taken up by sketchup as it appeared in its original form in 2000. Although the resulting images look a little primitive from today’s perspective, for the time it is very ...

Wednesday, April 21, 2010. Liquids, Smoke, and Soap Bubbles -. Reflections on Materials for Ephemeral User Interfaces. University of Hamburg,. 33537 Hamburg, Germany. Tanja Döring, Albrecht Schmidt. University of Duidburg-Essen,. 45117 Essen, Germany. This article presents an interface based on the creation manipulation, and short life of bubbles. The choice of this implementation encourages the users to interact with a medium that is very fragile, has a short life and exhibits random behavior. An intere...

http://manojcst.blogspot.com/2010/05/xwand-ui-for-intelligent-spaces.html
Combining Sight and touch. Wednesday, May 5, 2010. XWand: UI for intelligent spaces. Goal: to build an interaction device which can be used to point and interact with multiple devices around the user. (including voice medium). Orientation - combination of magnetometer and accelerometer. Can be affected by the metal in the environment. Position - uses vision techniques to find the 3D position from 2 - 2D position. Tracks 2 IR LEDs. The wand is familiar to the wand simulated with Wii for Wiizards games and...
