LINE-OF-SIGHT DETECTION DEVICE AND HEAD MOUNTED DISPLAY DEVICE - A simplified explanation of the abstract
This abstract first appeared for US patent application 18395406 titled 'LINE-OF-SIGHT DETECTION DEVICE AND HEAD MOUNTED DISPLAY DEVICE
The line-of-sight detection device described in the patent application includes a lens, an image sensor positioned on an edge of the lens, and multiple light sources arranged along the edge of the lens. The distribution of light sources around the optical axis of the lens ensures optimal coverage for detecting line-of-sight.
- The device consists of a lens, image sensor, and multiple light sources.
- Light sources are strategically placed around the optical axis of the lens for maximum coverage.
- The number of light sources per degree is highest on the opposite side of the image sensor with respect to the optical axis of the lens.
- This configuration allows for accurate line-of-sight detection in a 360° range.
Potential Applications: - Virtual reality systems - Eye tracking technology - Security systems - Human-computer interaction - Gaming devices
