Problems solved by technology

[0003] TV has always been an indispensable entertainment product in people's daily life. With the development of digital TV, the function of TV is becoming more and more powerful, and the complexity of its control is also gradually increasing. The traditional infrared remote control has become more and more It is increasingly unable to meet people's requirements for TV control
However, there is an obvious gap between the gesture-based control method and the diversity of TV control in the gesture-based control method; at the same time, the voice-based control method also has technical gaps in the expression diversity of the same semantics and the certainty of control instructions. Difficulty in realization

Embodiment Construction

[0028] The TV control method based on line-of-sight tracking in the present invention is applied to indoor scenes where multiple users are observed at medium distances. as figure 1 The system shown is illustrated as an example. First, two cameras 1 and 2 capable of clearly photographing the pupils of the human eye are installed on the TV so as to accurately estimate the gaze point, and a TV gaze manipulation trigger button 4 is set on the television to start gaze tracking manipulation. These two cameras should be able to clearly photograph the pupils of the human eye at about 3 meters (generally 2 to 4 meters).

[0029] The method of the present invention is introduced by taking the control of a multifunctional digital TV as an example.

[0030] When the TV switch 3 is turned on, the cameras 1 and 2 are started to shoot the scene of the user watching the TV in real time. Perform face detection in the captured scene according to facial features, lock and track each detected ...

Abstract

The invention discloses a television (TV) control method based on sight-tracking, which firstly installs two cameras which can clearly shoot human eyes pupil, and sets a TV sight control triggering button on the TV to start the control of the sight-tracking, and specifically comprises the following steps: (1) locking and tracking human faces of all viewers, detecting the human faces in real time in images of the TV viewers shot by the cameras, locking and tracking all detected human faces; (2) estimating fixation points of all viewers, respectively locating the human eyes in each tracked human face region to realize the fixation point estimation of multiple users; and (3) using the sight to realize the TV control, determining a TV control button selected by the viewer according to an estimated fixation point position of the viewer, thereby, enabling the TV to perform the corresponding action to realize the intelligent control to the TV. People can naturally, conveniently and rapidly control the TV by using the TV control method.

Description

technical field [0001] The invention relates to a TV control method based on line of sight tracking, and belongs to the technical field of TV control. Background technique [0002] With the rapid development of science and technology, intelligent control technology, as a symbol of high technology, has become a research direction that has attracted much attention in recent years. Various emerging intelligent control technologies based on eye tracking, gesture input or voice recognition have emerged as the times require. Among them, the intelligent control technology based on line of sight tracking has been rapidly developed in the field of intelligent control technology due to its natural, rapid, convenient and effective characteristics. Its application scope also ranges from the initial visual psychology research, the development of assistance for the disabled to commercial advertisement evaluation, robot control and other fields, and gradually enters people's daily life. ...
