Embodiment 1

[0048] Please refer to figure 1 , is an electronic device provided in the embodiment of the present application, including:

[0049] The light transmission part 10 is used to receive the reflected light reflected by the user's eyes, and output the outgoing light after the reflected light is transmitted in the light transmission part;

[0050] The imaging component 11 is configured to receive the outgoing light and form a first image at least including the user's eyes.

[0051] In the embodiment of the present application, the electronic device further includes:

[0052] The light-emitting component 12 is used to emit infrared light, and the infrared light is transmitted to form an infrared input light irradiated on the user's eyes, wherein the infrared input light is reflected by the eyes to become the reflected light.

[0053] In a specific implementation process, the light-emitting component 12 is specifically an infrared light emitter, which is used to emit infrared light...

Abstract

The invention discloses an electronic device. The electronic device comprises a light transmission part, used for receiving reflected light formed by reflection through eyes of a user, wherein emergent light is output after the reflected light is transmitted in the light transmission part; and an imaging component, used for receiving the emergent light and forming a first image at least containing the eyes of the user. Through the technical scheme, the technical problem of low precision of eyeball tracking based on an obtained human eye image by an electronic device in the prior art is solved.

Description

technical field [0001] The invention relates to the field of electronic technology, in particular to an electronic device. Background technique [0002] With the rapid development of computer terminal equipment, the types of computer terminal equipment are rapidly updated, such as smart bracelets, smart watches, smart glasses, etc. also appear in people's lives. [0003] For the smart glasses products in the prior art, it can have a unique application prospect of superimposing and presenting real information and real scenes, and even interacting with each other. However, due to the size and display of the current smart glasses products, it is difficult to manually operate the operation pointer through mouse and touch to realize human-computer interaction. At present, the control of the display interface is realized through eye tracking. , while the eye tracking in the prior art mainly obtains the pupil image of the human eye through a camera. [0004] In the process of imp...
