Optical Finger Navigation

The Optical Finger Navigation (OFN) series are built to provide full flexibility on space-constrained smart controller interfaces.
 
When a user moves a finger across the surface of the OFN product, the built-in infrared light source will illuminate the microscopic patterns on the finger surface and reflect the patterns to the built-in optical CMOS image sensor. Any further finger movements identified from the CMOS image sensor will be converted to dual-axis data by algorithms, with the amount of movement interpreted as the number of counts.
 
PixArt’s OFN series provides compact optical navigation modules/sensors using OFNavi™ technology, each comes with distinctive features such as a high 4000cpi programmable resolution, heart rate detection, slim type, sunlight cancellation, and compliance with automotive-grade standards. By incorporating our free-/2-/4-/8-direction navigation technologies with smart TV controllers, automotive media systems, steering wheels, laptops, and medical devices, users are able to enjoy a convenient controlling experience anywhere, anytime.
 
OFNavi™ utilizes PixArt's proprietary Optical Finger Navigation (OFN) technology to enable miniaturized optical navigation systems with high performance and low power consumption. By replacing the conventional mechanical moving parts with PixArt's advanced algorithms in the OFN SoC, the OFNavi system not only eases further integration but empowers and inspires wearables HMI in every way.
