Product Overview

ATLab proprietary technology enables optical finger navigating input device in reality.
Optical Finger Navigation Sensor ATA2985 provides the mouse-like functionality in graphic user interface of modern portable display devices. Cursor can move smoothly anywhere by pixel-by-pixel movement. Compared with touch panel, arrow keypads and joystick, the Optical Finger Navigation Sensor produces much finer resolution and higher environment stability.
In the Optical Finger Navigation Sensor, the image sensor captures “snapshot” of the finger movement few thousand times per second and the navigation engine determines direction and magnitude of finger movement.

Patented technologies of “Touch-On Power-On” and "Smart LED On” are applied to reduce power consumption for portable electronics. Also the protocol of ATA2985 is I2C, so users are able to select for more performance by I2C bus.
