The Optical Finger Navigation (OFN) series are built to provide full flexibility on space-constrained smart controller interfaces.
 
When a user moves 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 number of counts.
 
PixArt’s OFN series provide up to 4 types of compact optical navigation modules/sensors, each comes with distinctive features such as high 4000cpi programmable resolution, heartrate 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, we offer our users an enjoyable and convenient controlling experiences anywhere, anytime.
