CONTROL OF DISPLAY CONTENT BY MOVEMENT ON A FIXED SPHERICAL SPACE

摘要

An apparatus for control of display content (the display content on screen 26) of a portable computer (20) with the use of user initiated motion. Calculations of motions of the device can be made based on the "Javel arc" (104,110), the preferential motion arc along which the device (20) travel. Additionally, the double integration of each accelerometer required in a conventional device is replaced by two magnetic sensors (1004,1006).
