International ClassB41J 005/08AbstractA data input device particularly suited for computers includes a housing which also contains a computer mouse. The mouse functions are executed by moving the entire housing member, and the fingers never move away from their constant "home" key positions for the data input keys. The normal left and right hand keyboard functions are split between two separate keyboard housings adapted to underlie the palms of the left and right hands, respectively. A mouse is in one or both of these housings. Finger wells are provided for the fingers of the operator along with a thumb well in each keyboard member. Data input keys are mounted at various positions within these wells for producing keyed input data to the computer; and the mouse (mice) has (have) a surface movement detecting apparatus for inputting spatial mouse movement signals to the computer.Other References
