Embodiment Construction

[0022] When a person is reading aloud, the movements of the eyes and the mouth can be regarded as synchronous, and the position of the calibration content corresponding to the voice information read out can indirectly reflect the position of the human eye. Based on this point, the embodiment of the present invention provides a method for calibrating parameters of an eye tracking system of an electronic device based on voice input.

[0023] In the embodiment of the present invention, certain calibration content can be displayed on the display interface of the electronic device, and the user can read aloud according to the calibration content displayed on the display interface, that is, the user inputs voice information to the electronic device. When the electronic device receives the voice information input by the user, the electronic device can convert the voice information into text content or picture feature information, and match it with the calibration content of the displa...

Abstract

The embodiment of the invention provides a parameter calibration method of an eye tracking system and electronic equipment. The method is applied to the electronic equipment with the eye tracking system, and comprises the steps of obtaining an eye staring position determined by the eye tracking system at the moment when target voice information is input; determining a target position in which target calibration content corresponding to the target voice information is located; according to the eye staring position and the target position, calculating calibration data, wherein the calibration data is used for calibrating parameters of the eye tracking system. In this way, according to the parameter calibration method of the eye tracking system and the electronic equipment, based on voice input of a user, the purpose of calibrating the parameters of the eye tracking system can be achieved. By utilizing a principle of synchronizing the human eyes and mouth, the calibration is precise, and the operation is simple and convenient.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a parameter calibration method and electronic equipment of an eye tracking system. Background technique [0002] Eye tracking technology is an application technology for controlling electronic devices through eyes, for example, game map control based on eyeball movement, or TV icon control based on eyes, and so on. The eye tracking system judges the gaze direction of the eyes by detecting the deviation of the pupils, so as to realize the interaction with electronic devices. The eye tracking system needs to establish the functional relationship between the eye position characteristic parameters and the position parameters of the electronic device display interface. However, due to the differences in the eye features of different human eyes, it is possible for different human eyes to control objects on the electronic device display interface. There is a deviation. It can b...
