The Optical Finger Navigation (OFN) series is designed to provide full flexibility for smart controllers in space-constrained environments.

When a user glides their finger over the surface of an OFN product, an integrated infrared light source illuminates the microscopic patterns on the finger. These patterns are reflected back to an optical CMOS image sensor, which detects the movements. The sensor’s data is then processed by algorithms to generate dual-axis information, with the extent of movement quantified as a count.

PixArt’s OFN series features compact optical navigation modules and sensors equipped with OFNavi™ technology. Notable features include high 4000 CPI programmable resolution, heart rate detection, a slim design, sunlight rejection, and compliance with automotive-grade standards. By integrating our 2-, 4-, 8-direction, or free navigation technologies with smart TV controllers, automotive media systems, steering wheels, laptops, and medical devices, users can enjoy a seamless and convenient control experience anytime, anywhere.
