Tilt input device
First Claim
1. A handheld input device for controlling cursor operations on a graphic display comprising:
- an outer housing having a cubic curved bottom half and a cubic curved top half;
a plurality of input buttons;
a sensing apparatus with means of recognizing pitch and roll angular displacements relative to a basis vertical axis;
an electronic input processor coupled to said sensing apparatus and said graphic display that effects pitch rotational input into vertical movement of said cursor on said graphic display and effects roll rotational input into horizontal movement of said cursor on said graphic display.

Abstract
The invention herein is an input device for a graphic display, where cursor movements are controlled using pitch and roll rotations of the device by the user. Pitch rotational input corresponds to cursor movement along the vertical Y axis of the graphic display, and roll rotational input corresponds to cursor movement along the horizontal X axis. The top side and bottom side of the housing are cubic curved to allow for comfort to the user and ease of rotating device. The device of the invention can operate on all surfaces and in freespace. The invention includes angular displacement sensing methods for two types of technologies in common use, rotary encoder sensors and optical position tracking sensors. One embodiment of the invention allows the user to select the asis vertical axis from which the sensors will measure angular displacement. This feature will allow the device to be operated at multiple angles; traditionally, as on a desktop surface in the horizontal plane, and at custom positions, such as holding the device angled down by one'"'"'s side or with their arms crossed.
