INSTRUCTION DEVICE AND COMMUNICATING METHOD

摘要

An instruction device is provided for communicating an instruction and an icon in an image area, and includes a motion sensing unit and a processing unit. The motion sensing unit senses a first motion to generate a corresponding first signal. The processing unit generates a first trajectory to determine a first region in the image area in response to the corresponding first signal for a decision whether the icon shall be or has been selected according to a relationship between the first region and a second region where the icon is displayed in the image area.
