Abstract

The invention is a hand held computer device having a housing including a top or upper surface, a lower surface and finger saddle ridge protruding downwardly from the lower surface. The finger saddle ridge has two finger receiving surfaces and is sized to accommodate a pair of human fingers such that a first finger contacts the front surface of the finger saddle and a second finger contacts the rear surface of the finger saddle. When an operator'"'"'s fingers straddle the finger saddle ridge, the hand held computer device pivots about a pivot point defined between the fingers. The device can thus be readily maneuvered into a downward pivoting position, highly useful for decoding bar codes, and an upward pivoting position, highly useful for display viewing and applications involving display viewing such as web browsing and data input.
