SYSTEM AND METHOD FOR MOTION DETECTION AND INTERPRETATION

摘要

A motion detection and interpretation system comprising a camera plus an infrared transmitter/receiver paired with a single reflective surface that records image data from two vantage points. The camera is connected to a computer and a display screen. The system creates a virtual touch screen for interaction with the display screen. The components of the system can be protected behind a transparent barrier while the virtual touch screen is provided for user interaction thus preventing user interference with, deterring vandalism and theft of, and prolonging the usable life of the equipment. In addition to finite hand movements detected by the virtual touch screen, the system can also simultaneously perform facial recognition and body movement recognition. The system is capable of interpreting multi-touch inputs. All recognitions are defined in the computer to carry out preprogrammed responses.

主权项

1. A computer system for interpreting distance and position as a set of computer commands comprising:
a display; a camera, positioned adjacent the display; a mirror, positioned adjacent the camera, so as to provide a reflected field of view; a distance sensor, positioned adjacent the display, so as to provide distance to target information; a computer, connected to the camera and the distance sensor, programmed to carry out a computer implemented method having the steps of:
defining an action area within the reflected field of view;retrieving a set of reflected distance to target information from the distance sensor, in the action area, in a first coordinate system;retrieving a set of position information, from the camera, in the first coordinate system;retrieving a set of image information, from the camera, in a second coordinate system;translating the set of reflected distance to target information and the set of position information, from the first coordinate system into the second coordinate system;interpreting the set of reflected distance to target information and the first set of position information as a computer command of the set of computer commands, based on the set of image information.
