Problems solved by technology

[0003] However, when illuminated by an infrared light source, a light-emitting diode (Infrared Radiation Light Emitting Diode, referred to as IR LED) is usually used for illumination. However, the conversion rate of IR LED from electrical energy to light energy is low, that is, the luminous efficiency is low. , which in turn leads to high heat generation, which causes high heat generation and high energy consumption of the equipment, which affects the performance of the equipment
[0004] In addition, the front cameras on mobile terminals such as mobile phones and tablet computers are generally not equipped with infrared cameras, so the corneal reflection method cannot be used to track the eyeballs, so the tracking accuracy is very low

Description

technical field [0001] The present application relates to the field of mobile computing equipment, and in particular to a laser-based eye tracking method and terminal equipment. Background technique [0002] At present, the eye tracking technology usually uses the corneal reflection method to track the sight. First, the infrared light source is used to provide scene illumination, and then based on the infrared camera, the reflection points formed on the user's cornea are collected, and then eye tracking is carried out according to the collected images. [0003] However, when illuminated by an infrared light source, a light-emitting diode (Infrared Radiation Light Emitting Diode, referred to as IR LED) is usually used for illumination. However, the conversion rate of IR LED from electrical energy to light energy is low, that is, the luminous efficiency is low. , which in turn leads to high heat generation, resulting in high heat generation and high energy consumption of the d...
