Disclosed Anonymously

On mobile devices, sometimes it is not convenient or possible to use the thumbwheel to navigate through the user interface. For example, the user may have a thumb injury, repetitive strain injury, etc.

The proposed solution utilizes a gyroscope or accelerometer integrated into the device. The gyroscope will replace a trackwheel or scrollwheel on the device, wherein functions are selected by tilts or various motions of the device.

There may be existing mobile devices that have integrated tilt control based on using the ground direction as the reference.  However, our solution will be to be able to have tilt control no matter what position the handheld is in.  This is achieved by only responding to the gyroscopic motions only under user intervention (i.e., the user depresses a button that activates the tilt function).  The software will then respond to corresponding axis tilts based on the position of the handheld when the button was first depressed.  The user will stop the function when they release the button.  Since we can get four directions of tilt, we can increase the functionalities (e.g., Left/Right tilt scrolls, Up/Down tilt zooms)
