Abstract
There is provided a user interface system including a slave device and a master device. The slave device provides light of two different wavelengths to illuminate a finger surface, receives reflected light from the finger surface to generate a plurality of image frames, calculates and outputs an image data associated with a predetermined number of the image frames. The master device calculates a contact status and a displacement of the finger surface and a physiological characteristic of a user according to the image data.
