Portable data processing unit with gravity-controlled sensors for screen and screen orientation

摘要

The portable data processing device has an integrated screen displaying one or more graphics or other objects represented therein. The screen has a gravity control sensor for measuring the spatial directivity of the screen. The apparatus has a programmed data processor for controlling a non-stop behavior pattern in a predetermined range of spatial orientations that convey a predetermined selection of objects. The operation can be used in the way of a joystick. As a result it can lead to off-screen dumping, loading, or transfer of related objects.
