Optical sensor improves gesture recognition reliability
A single optical sensor improves sensing accuracy and reliability, compared with existing gesture recognition solutions, says Analog Devices. The ADUX1020 measures a subject’s position, proximity, and gestures from a single sensor rather than using multiple sensors which can be inaccurate, as the sensors “see” objects differently from varying angles.
The single-point sensing used in this optical sensor improves reliability says the company, reduces design complexity and system cost, with fewer components.
In addition to single-point sensing, the optical sensor has high ambient light rejection, which allows reliable and accurate operation under challenging lighting conditions. Other optical sensors are often challenged by ambient light from sources like full sun, high frequency LED and fluorescents, all of which can disrupt the sensor’s ability to interpret gestures accurately, points out the company.
The sensor is sampling now, and available in a 2.0 x 3.0mm, eight-lead LFCSP. An evaluation board, the ADUX102BCPZ-eval-SDP, is also available, with an add-on board with high power LED for longer range operation.
