LinLED: Low latency and accurate contactless gesture interaction

Résumé

An innovative gesture interface called LinLED is described. Tradi- tional interfaces often suffer from limited tracking range and sig- nificant latency when locating fingers or hands. However, LinLED presents a game-changing solution. LinLED comprises a 1D-array of photodiodes and offers great precision in locating hands or fin- gers moving laterally in the air. Its accuracy is as small as 1 mm, which is ten times smaller than the photodiode pitch. Moreover, the latency is as fast as 1 ms, all thanks to its pure analog processing. LinLED can accurately detect any object reflecting infrared within a range of approximately 30 cm by 40 cm. Additionally, LinLED is sensitive to vertical motion (Z-axis motion), enabling the detection of three different types of gestures: selection, swipe, and graded smooth lateral movement. LinLED represents a significant advance- ment in gesture interfaces, offering high precision, minimal latency, and the ability to detect various gestures effectively.
