Visual perception device and control method thereof

Abstract

The invention relates to a visual perception device which comprises a processing unit, a camera unit, a display unit, a display screen and a storage unit, wherein the processing unit comprises an image processing module, a visual calibration module, a cursor control module and an object control module; the image processing module is used for controlling the camera unit to intake the visual images of the eyes of a user when the user stares at a target object in the display screen, processing the visual images to obtain a visual focal position, and computing visual calibration offset; the visual calibration module is used for carrying out coordinate calibration on the visual focal position according to the visual calibration offset; the cursor control module is used for selecting the peripheral area of the visual focal point as a visual cursor to judge whether the dwell time of the visual cursor is longer than a set time; and the object control module is used for controlling the visual cursor to select the target object when the dwell time is longer than the set time, and controlling the next target object to enter a visual cursor area when the dwell time is shorter than or equal the set time. The invention can reduce the unreliability of visual capture and the number of times of manual interaction, and realizes the effect of electricity saving and energy saving at the same time.

Description

technical field [0001] The invention relates to an electronic device and a control method thereof, in particular to a visual perception device and a method for controlling a target object in the visual perception device. Background technique [0002] Due to the continuous development of the human-computer interaction field of electronic devices (such as mobile phones), from the initial button interaction mode to the current pen touch and finger touch interaction mode, the human-computer interaction becomes more and more convenient. However, this mode of manually realizing human-computer interaction is somewhat difficult for disabled users or terminal users whose hand activities are limited due to certain diseases. Therefore, a capture technology based on eye control is gradually applied to electronic devices, that is, using visual perception to interact with electronic devices is a very good way of interaction. [0003] At present, there are devices for visual perception an...
