Patent ID: 11273367

Abstract:
A system for detecting an aim point on a display screen targeted by a user comprises a microcomputer that has at least a power source, a processor, a non-volatile memory, an I/O interface, and a display output. A hand held enclosure includes a camera having a field-of-view defined by an X-axis and a Y-axis, a user input, and a microcomputer interface to transmit camera data and user input data to the microcomputer. The aim point is a point located centrally in the field-of-view. The microcomputer is adapted to display two or more reference icons on the display screen, detect the reference icons using the camera, calculate the aim point on the display screen based on the position of the reference icons within the field-of-view of the camera, perform a function based on user input settings and the calculated value of the aim point, and repeat the process as necessary.
