Abstract
An electronic device including a casing, a control module, a micro-projecting unit and a motion sensing unit is provided. The control module is disposed in the casing. The micro-projecting unit is disposed on the casing and electrically connected to the control module. The micro-projecting unit is capable of projecting a projection beam to form a frame in a projection region. The motion sensing unit is disposed on the casing and electrically connected to the control module. The motion sensing unit is capable of sensing a motion in the projection region. The control module is capable of applying the motion sensed by the motion sensing unit to change the frame.
