Abstract
A computer input system for a computer generating images appearing on a screen. For the purpose of modifying the images appearing on the screen, a light generating device causes an auxiliary light image to appear on the screen. An image sensor responds to the auxiliary image, and a circuit responds to the sensor for causing auxiliary image information to be stored concerning the auxiliary light image. Another circuit responds to the stored auxiliary image information to supply the auxiliary light image information to the computer for utilization therein.
Claims100
An interactive optical input system for position control of equipment produced images, said equipment produced images including information images, comprising:
- visualization projection means for causing an equipment produced image to be projected onto a remote viewing surface;
- means for generating a position control image upon said surface;
- light sensing means for scanning the equipment produced image and the position control image on the remote viewing surface, said light sensing means including means for determining light sensing coordinate values for said position control image;
- means for storing predetermined reference coordinate values;
- signal processing means responsive to the predetermined reference coordinate values and to the determined light sensing coordinate values for the position control image for converting the light sensing coordinate values for said position control image to equipment coordinate values;
- means responsive to said equipment coordinate values of the position control image for generating a signal indicative of a positioning control command when said position control image is sequenced on and off;
- and
- whereby the command and the location of the position control image relative to said information image causes the equipment produced images to be modified.
A method for controlling equipment produced images, said equipment produced images including information images, comprising:
- projecting an equipment produced image onto a remote viewing surface for displaying the image thereon;
- generating a position control image on said surface;
- scanning the equipment produced image and the position control image on the remote viewing surface;
- determining light sensing coordinate values for said position control image;
- storing predetermined reference coordinate values;
- responding to the predetermined reference coordinate values and to the determined light sensing coordinate values for the position control image by converting the light sensing coordinate values for said position control image to equipment coordinate values;
- responding to said equipment coordinate values of the position control image for generating a signal indicative of a positioning control command when said position control image is sequenced on and off;
- and
- whereby the command and the location of the position control image relative to said information image causes the equipment produced images to be modified.
