Input system e.g. trackball, for e.g. inputting characters in e.g. personal computer, has selection items changed by turning/tilting/moving geometric object in multiple axes by user, until desired item appears in foreground of screen

摘要

The system has multiple grid-like selection items i.e. menu items, that are changed by turning/tilting/moving a geometric object e.g. polygon ball and cylinder, in multiple axes by a user, until a desired selection item appears in a foreground in a screen. The desired selection item is selected by interacting with the system. Multiple symbols are positioned on a flat surface of the geometric object, which is visualized as globe. A virtual keyboard is displayed on the screen, and a position detection unit detects position of fingers of the user and activates keys of the keyboard.
