Position indicating device for a digital computer
First Claim
1. An input device for use with a digital computer having a video display, for displaying the position of an indicator thereon and responsive to cursor key signals for moving said indicator, said device comprising:
- first transducing means for generating a first motion signal in response to said input device moving in a first direction;
second transducing means for generating a second motion signal in response to said input device moving in a second direction substantially perpendicular to said first direction;
a plurality of keys including a numeric keypad and a plurality of control keys for supplying input signals to said input device; and
means for processing said first and second motion signals and said input signals by supplying said input signals to said digital computer in the event said input signals are supplied to said input device, and for supplying input signals to said digital computer corresponding to the direction and amount of motion of said input device from said first and second motion signals, in the event no input signal from the plurality of keys is supplied to said input device.

Abstract
In the present invention an input device for use with a digital computer having a video display for displaying the position of an indicator thereon is disclosed. The input device has means for converting rotational motion signals into conventional cursor key signals and also has a plurality of keys which include a numeric keypad and a plurality of control keys. A program controls the input device such that in the event the key signals are supplied, then said key signals are supplied to the computer. However, if no key signal is supplied, then the motion signals are converted into key signals and are then supplied to the digital computer. The input device also can receive the input signal and reprogram the function of the keys in response to that one input signal. Still, the input signal caused by activation of one of the plurality keys can cause the suspension and resumption of the tranfer of the motion signals to the computer. Finally, activation of one of the plurality keys can cause the activation of one or more of the plurality of commands that are displayed normally in the periphery of the display without the device or the indicator being moved to the position of the command.

6. A position indicating device for use with a digital computer having a display for displaying the position of an indicator thereon and responsive to cursor key signals for moving said indicator, said position indicating device comprising:
-
first transducing means for generating a first motion signal in response to said device moving in a first direction; second transducing means for generating a second motion signal in response to said device moving a second direction, substantially perpendicular to said first direction; a plurality of keys, each for supplying an input signal to said device; and means for receiving a first input signal for permanently suspending the transfer of said one or more motion signals to said computer, in response thereto and for receiving a second input signal for thereafter resuming the transfer of said one or more motion signals to said computer in the absence of other input signals. - View Dependent Claims (7, 8, 9, 10)
