Eye-Movement Tracking Apparatus And Electronic Device - A simplified explanation of the abstract
This abstract first appeared for US patent application 18254812 titled 'Eye-Movement Tracking Apparatus And Electronic Device
Simplified Explanation
The patent application describes an eye-movement tracking apparatus and an electronic device. The apparatus includes a light source, lens group, hot mirror, and a compact camera module. The light source emits a light ray towards the user's eyeball. The reflected light ray forms two new light rays that are directed towards the lens group.
- The light ray reflected by the hot mirror undergoes multiple reflections to form a third light ray.
- The light ray reflected by the hot mirror also undergoes multiple reflections to form a fourth light ray.
- The number of reflections for the third and fourth light rays are different and are represented by natural numbers N and M, respectively.
- The optical component allows the third light ray to enter the image sensor while preventing the fourth light ray from entering the image sensor.
Potential Applications
- Eye-tracking technology for various applications such as gaming, virtual reality, and augmented reality.
- Medical applications for monitoring eye movements during surgeries or diagnosing eye conditions.
- Research and analysis of human visual behavior for marketing, user experience, and psychology studies.
Problems Solved
- Accurate and precise eye-tracking by capturing and analyzing the reflected light rays from the eyeball.
- Minimizing interference from unwanted light rays to improve the quality of eye-tracking data.
- Providing a compact and integrated eye-tracking solution for electronic devices.
Benefits
- Improved accuracy and precision in eye-tracking measurements.
- Enhanced user experience in applications utilizing eye-tracking technology.
- Compact and integrated design for easy integration into electronic devices.
Original Abstract Submitted
An eye-movement tracking apparatus and an electronic device are provided. The eye-movement tracking apparatus includes a light source, a lens group, a hot mirror, and a compact camera module. The light source is configured to emit a light ray to an eyeball of a user. The light ray is reflected by the eyeball to form a first light ray and a second light ray that are emitted to the lens group. The first light ray is reflected by the hot mirror for N times to form a third light ray. The second light ray is reflected by the hot mirror for M times to form a fourth light ray. Both M and N are natural numbers, and M and N are different. The optical component allow the third light ray to enter the image sensor, and prevent the fourth light ray from entering the image sensor.
