LinLED

Contactless Interface for gesture interaction

LinLED is an innovative gesture interface ((Viollet et al., 2023)). Traditional interfaces often suffer from limited tracking range and significant latency when locating fingers or hands. 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 thanks to its pure analog processing.

The LinLED contactless interface based on modulated infrared to locate hand or fingers in real time.
DEMO: A short video of LinLed in action can be found here and here (in french).
LinLED can locate hands or fingers along horizontal and vertical axes.
