Abstract: A wearable device including a skin sensor and a processor is provided. The processor is configured to receive an authentication data for authenticating a user when a wearing state of the wearable device is adjacent to a skin surface of the user, execute a predetermined function in response to a request when the authentication data matches a pre-stored data and the skin sensor determines that the wearable device does not leave the skin surface after the authentication data is received, and reject or ignore the request when the skin sensor determines that the wearable device leaves the skin surface before the predetermined function is executed.

Abstract: An optical navigation apparatus and an optical navigation method are provided. The optical navigation apparatus includes a light source unit, an image sensing unit, and a processing unit, wherein the processing unit is electrically connected to the light source unit and the image sensing unit. The light source unit generates a beam of light. The image sensing unit captures a plurality of images within a time interval. The processing unit determines that the beam of light is projected onto a touch object according to the images, calculates a piece of displacement information related to the touch object according to the images, generates a comparison result by comparing the piece of displacement information with a threshold, and sets a displacement resolution of the optical navigation apparatus according to the comparison result.

Abstract: There is provided a communication system including a transmission interface, a master device and a slave device. The transmission interface includes a TR/ACK channel configured to transmit a trigger signal and an acknowledge signal and a DA channel configured to transmit a normal data or a simplified data. The master device sends the trigger signal via the TR/ACK channel before data transmission begins. The slave device sends the normal data or the simplified data to the master device via the DA channel after receiving the trigger signal.
