The Perceptual Window Movies |
|
|
The perceptual window allows users to control the scrolling in a window
with head motions. Two modes of operation are possible: controlling the
rate of the scrolling, or directly controlling the position of the
window's viewpoint within its document space. The system has been tested against users, it allows significant improvements in task completion time after a short learning period (please refer to the publications at the bottom of the page for more details). |
