Abstract
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.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
182 words
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.
Claim 2
Dependent Claim
182 words
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.
Claim 3
Dependent Claim
39 words
The device of claim 1 further comprising: means for receiving an input signal caused by activation of one of said plurality of keys and for reprogramming the function of said plurality of keys in response to said input signal.
Claim 4
Dependent Claim
41 words
The device of claim 1 further comprising: means for receiving an input signal caused by activation of one of said plurality of keys and permanently suspending the transfer of said one or more motion signals to said computer in response thereto.
Claim 5
Dependent Claim
30 words
The device of claim 1 wherein said display also displays a plurality of commands positioned generally to the periphery of said display and activated by said indicator being positioned thereon.
Claim 6
Dependent Claim
41 words
The device of claim 4 further comprising: means for receiving an input signal caused by activation of one of said plurality of keys and for activating one or more of said plurality of commands without said device and indicator being moved.
Claim 7
Dependent Claim
147 words
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.
Claim 8
Dependent Claim
147 words
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.
Claim 9
Dependent Claim
39 words
The device of claim 6 further comprising: means for receiving an input signal caused by activation of one of said plurality of keys and for reprogramming the function of said plurality of keys in response to said input signal.
Claim 10
Dependent Claim
87 words
The device of claim 6 wherein said receiving means further comprising: 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 device, and for supplying input signals to said digital computer corresponding to the direction and amount of motion of said device from said first and second motion signals, in the event no input signal from the plurality of keys is supplied to said device.
Claim 11
Dependent Claim
30 words
