Abstract

Abstract:
The present invention relates to a cursor control system for use with a computer having a CRT display. The system includes a hand mounted signal generator for generating an X axis cursor position signal and a Y axis cursor position signal. The generator includes an X axis array of light transmitting elements, an X axis array of light receiving elements, a Y axis array of light trans-mitting elements and a Y axis array of light receiving elements. A space is provided for separating the X axis array of light transmitting elements from the X axis array of light receiving elements and for separating the Y axis array of light transmitting elements from the Y axis array of light receiving elements. An interrupting unit is provided which is controlled by a finger of the hand partially located within the space for interrupting light energy from reaching individual light receiving elements in the X axis and Y axis array of light receiving elements, the light energy having been transmitted from associated individual light transmitting elements in the X axis and Y
axis array of light transmitting elements. A scanner is provided for sequentially scanning the X axis and Y axis array of light transmitting elements and the X axis and Y
axis array of light receiving elements to thereby produce the X axis cursor position signal and the Y axis cursor position signal.

Claims (12)

Claims:
1. A cursor control system for use with a computer having a CRT display, said system including:
(a) a hand mounted signal generator for generating an X axis cursor position signal and a Y axis cursor position signal, said generator including a X axis array of light transmitting elements, a X axis array of light receiving elements, a Y axis array of light transmitting elements and a Y axis array of light receiving elements;
a space for separating said X axis array of light transmitting elements from said X axis array of light receiving elements and for separating said Y axis array of light transmitting elements from said Y axis array of light receiving elements;
interrupting means controlled by a finger of said hand, partly located within said space, for interrupting light energy from reaching individual light receiving elements in the X axis and Y axis arrays of light receiving elements, said light energy having been transmitted from associated individual light transmitting elements in said X axis and Y axis array of light transmitting elements; and (b) scanning means for sequentially scanning said X
axis and Y axis arrays of light transmitting elements and said X axis and Y axis arrays of light receiving elements to thereby produce said X axis cursor position signal and said Y axis cursor position signal.
2. The system of claim 1 wherein said signal generator is in the form of a box having top and bottom walls and left and right side walls and wherein said X
axis array of light transmitting elements is located on either the top or bottom wall and the X axis array of light receiving elements is located on either the bottom or top wall and the Y axis array of light transmitting elements is located on either the left or right side wall and the Y axis array of light receiving elements is located on either the right or left side wall, so that said space is partly define by the height and width of said box.
3. The system of claim 2 wherein said box has a front wall which includes a pivot and wherein said interrupting means is in the form of a rod which attaches at one end around said finger, which is secured to said pivot in its middle region and which has its other end located in said space.
4. The system of claim 2 wherein said box has a rear wall which includes a pivot and wherein said interrupting means is in the form of a rod which attaches at one end around said finger and at its other end to said pivot and which has a middle region which is in said space.
5. The system of claim 4 wherein said X axis array of light transmitting elements and receiving elements and said Y axis array of light transmitting and light receiving elements are located on the top and bottom and left and right side walls of said box proximate the front of said box in a planar arc having its center at said pivot.
6. The system of claim 3 wherein said X axis array of light transmitting elements and light receiving elements and said Y axis array of light transmitting elements and light receiving elements are located on the top and bottom and left and right side walls of said box proximate the rear of said box in a planar arc having its center at said pivot.
7. The system of claim 5 or 6 wherein each element in said X axis and Y axis array of light transmitting elements is a discrete light emitting diode and each element in said X axis and Y axis arrays of light receiving elements is a discrete phototransistor.
8. The system of claim 1, wherein said scanning means is comprised of an X axis control circuit and a Y axis control circuit.
9. The system of claim 8 wherein the X axis control circuit is connected to said computer and receives from said computer a sequence of address signals, said X axis control circuit being connected to said X axis array of light transmitting elements and light receiving elements, said X axis control circuit producing a sequence of signals in correspondence with said address signals for sequentially turning on each individual light transmitting element in said X axis array of light transmitting elements and sequentially connecting each associated light receiving element in said X axis array of light receiving elements to a common X data line to generate said X axis cursor position signal.
10. The system of claim 9 wherein the Y axis control circuit is connected to said computer and receives from said computer said sequence of address signals; said Y
axis control circuit being connected to said Y axis array of light transmitting elements and light receiving elements, said Y axis control circuit producing a sequence of signals in correspondence with said address signals for sequentially turning on each individual light transmitting elements in said X array of light transmitting elements and sequentially connecting each associated light receiving element in said X axis array of light receiving elements to a common Y data line to generate said Y axis cursor position signal.
11. The system of claim 10 wherein when said X axis control circuit is "ON" said Y axis control circuit is "OFF" and wherein when said Y axis control circuit is "ON"
said X axis control circuit "OFF".
12. The system of claim 10 wherein said X axis array of light transmitting and light receiving elements and said Y axis array of light transmitting and light receiving elements each include 32 individual elements.
