Embodiment 1

[0043] figure 1 A schematic structural diagram of the eye tracking module of the video glasses provided by the embodiment of the present invention, as shown in figure 1 As shown, the eye tracking module of the video glasses includes: a transmitting component 10 , a receiving component 20 and a main control component 30 .

[0044] In this embodiment, the transmitting component 10 is used to emit invisible light to the user's eyeball; the receiving component 20 is used to receive the invisible light reflected by the eyeball, and generate an electrical signal under the irradiation of the invisible light; the main control component and the receiving component The connection is used for obtaining the position of the eyeball according to the electric signal.

[0045] Wherein, the video glasses may be a virtual reality glasses device or an augmented reality glasses device.

[0046] Specifically, the main control component 30 calculates the direction of the light reflected by the us...

Embodiment 2

[0077] Figure 9 The flow chart of the eye tracking method for video glasses provided by the embodiment of the present invention is realized by using the eye tracking module of video glasses provided in Embodiment 1, wherein the eye tracking module of video glasses includes: a transmitting component, a receiving component and a main control components, such as Figure 9 As shown, the eye tracking method of the video glasses provided by the embodiment of the present invention specifically includes the following steps:

[0078] Step 110, receiving an electrical signal.

[0079] Step 120, obtain the position of the eyeball according to the electric signal.

[0080] Specifically, step 120 specifically includes: calculating the direction of the light reflected by the user's eyeballs to the receiving component based on the position where the electrical signal is generated, the light emitting direction of the transmitting component, the position of the user's eyeball, the position ...

Abstract

Embodiments of the present invention provide an eye tracking module for video glasses, a method thereof, and video glasses, wherein the eye tracking module for video glasses includes: a transmitting component, a receiving component, and a main control component; The user's eyeball emits invisible light; the receiving component is used to receive the invisible light reflected by the eyeball, and generates an electrical signal under the irradiation of the invisible light; the main control component is connected to the receiving component to obtain the position of the eyeball according to the electrical signal . The embodiment of the present invention achieves eye tracking through the cooperation of the transmitting component, the receiving component and the main control component, avoiding the installation of a device reflecting invisible light or a camera for collecting infrared light, which not only makes the structure of the eye tracking module simple, but also reduces the Takes up volume.

Description

technical field [0001] Embodiments of the present invention relate to the technical field of human-computer interaction, and in particular to an eye tracking module for video glasses, a method thereof, and video glasses. Background technique [0002] Eye tracking technology is a technology that uses mechanical, electronic, optical and other detection methods to obtain the subject's current "gaze direction".
