Common Applications

This sensor is meant to track direct-contact motion from a fingertip. Common applications are for human-interfacing in devices such as smartphones, video game controllers, or a steering wheel in a car. The sensor comes as an entire module with a cover and FPC. The sensor would report a number of counts depending on how much the sensor sees that the contacting surface has moved. These counts can be used for controls (e.g. Let's say swiping your finger from left-to-right outputs +100 to +150 counts in the deltaX direction depending on the motion. After detecting 50 counts, increment volume by 1).
