General Description
The TMG399x family of IR gesture sensor modules provides a highly integrated solution
offering 5 functions essential for maximizing end user experience in today’s advanced
communications and consumer electronics enabling a coherent display and touchless user interface. Integrating touchless IR gesture detection, color, ambient light &
proximity sensors, LED and Mobeam™ Barcode Emulation functionality provides system
engineers enhanced design flexibility and efficiency. The TMG3992 offers the industry’s
smallest footprint with a 7.9mm2 module package ideally suited for applications such as
mobile phones where area efficiency is critical for device functionality.
Gesture detection utilizes four directional photodiodes to sense reflected IR energy
then converts this data into physical motion information including: velocity, direction
and distance. The gesture engine features automatic ambient light subtraction, crosstalk
cancellation, dual 8-bit data converters, power saving inter-conversion delay, 32-dataset
FIFO, and interrupt driven I2C communication. The gesture engine accommodates
a wide range of device gesturing requirements from simple North-South-East-West
gestures to more complex gestures events. Power consumption and noise are minimized with adjustable IR LED timing and optimized gesture algorithms.
