Abstract: A wireless position tracking device, a display system, and a wearable device are provided. The wireless position tracking device includes a rigid body, point light sources, a motion sensor, and a wireless transmission module. The rigid body has an inner concave surface, a head, a connecting portion, and a tail. The connecting portion connects the head and tail. The point light sources are fixed to positions outside the inner concave surface. The motion sensor locates in the rigid body for sensing a motion thereof and generating motion information. The wireless transmission module locates in the rigid body and electrically connects the motion sensor for wirelessly transmitting the motion information to the head-mounted device. An image capturing module of the head-mounted device captures a pattern formed by the point light sources. The head-mounted device calculates a relative position of the wireless position tracking device according to the pattern and motion information.

Abstract: An electronic device includes an upper housing, a lower housing, an elastic element, and a connecting device. The upper housing includes a latching device and a groove. The lower housing includes a latching device for fastening the latching device of the upper housing. A plate portion of the connecting device is inserted into the groove of the upper housing, and a circular component portion of the connecting device is connected to the lower housing of the electronic device in a rotatable manner. A first end of the elastic element is connected to the lower housing of the electronic device, and a second end of the elastic element is connected to the circular component portion of the connecting device.
