Pressure sensitive electronic device
First Claim
1. An electronic device comprising:
- a case, said case having a top portion, a side portion, and a bottom portion;
a display having information displayed thereon, said display incorporated into said case, said information including a cursor in a first position;
a processor contained in said case, said processor connected to said display; and
a pressure sensor, operatively coupled to said case and to said processor, for detecting pressure on said side portion of said case without the use of keys or other input devices, said processor sending signals to said display causing the cursor on said display to move from said first position in a first direction to a second position, responsive to said pressure sensor detecting pressure on said side portion of said case in said first direction.

Abstract
A pressure sensitive electronic device has a display, a case, a processor, and a pressure sensor, such as one or more force sensitive resistors. When the pressure sensor detects pressure on the case, the information displayed on the display is changed. Pressure in one or more dimensions (X, Y, and/or Z) on the case is detected by the pressure sensor. Most commonly, the information that is changed on the display is the repositioning of a cursor on the display, although switching between various operating modes and/or writing on the device can also be performed. The cursor is repositioned corresponding to the direction and magnitude of the pressure detected on the case. Pressure can also be used to execute an operation corresponding to the position of the cursor on the display. Keys or other input devices (mouse, trackball, etc) are not required to control the movement of the cursor on the display, execute operations, or switch between various operating modes of the device.
