摘要： A touch system with track detecting function includes a touch pad for sequentially sensing a plurality of positions of an indication object at a plurality of moments in order to detect a track of the indication object on the touch pad, and a processor for continuously generating motion vectors according to the track of the indication object on the touch pad, for generating a candidate motion vector according to at least one motion vector, and for nonlinearly generating a target motion vector according to the candidate motion vector in order to move a target shown on a display panel. Each of the motion vectors represents a difference between a position of the indication object and a next position of the indication object.

摘要： A lift detection method for an optical mouse and an optical mouse with a lift detection function are presented. An average brightness value of pixels captured by part of sensing units of an image sensor is computed after each scanning, and two average brightness values obtained from two adjacent times of scanning are compared, to determine a brightness change of the pixels in each scanning, thereby acquiring a placing state of the optical mouse accordingly.

摘要： A method for detecting an object and a touchable device are presented, which is capable of detecting an object having a fingerprint feature on an operation interface of the touchable device. An image sensor is used for acquiring acquiring an image on the operation interface, and the acquired image is converted into a signal denoted in a frequency domain by using a frequency conversion function. Signals at a medium-high frequency (MHF) signal region among the signals of the frequency domain are analyzed, so as to generate a first signal and a second signal according to a distribution of the signals of the frequency domain. The first signal indicates existence of the object on the operation interface, and the second signal indicates inexistence of the object on the operation interface.
