Description

Handheld Electronic Devices

The present invention relates to a handheld electronic device, and in particular to a handheld electronic device used as a controller for a virtual image display device.

With the evolution of electronic technology, technologies for simulating sensation, perception and/or environment, such as virtual reality (Virtual Reality, VR), augmented reality (Augmented Reality, AR), mixed reality (Mixed Reality, MR) Or Extended Reality (XR), which is quite popular today. In order for the user to perceive the simulated environment as a real environment, it is necessary to obtain the position of the user or operator's hand in space, so that the virtual reality, augmented reality, mixed reality or extended reality can be changed corresponding to the position of the user or operator's hand display image on the monitor. For example, a virtual reality product may include a hand-held controller and a display, and the position of the hand-held controller will be tracked, and corresponding to the tracked position of the hand-held controller, the behavior of the user operating the hand in the display image of the display can be moved .

At present, the most common design of the hand-held controller is a ring-shaped tracking object (tracking object), which uses an external detector to detect the light-emitting diodes on the ring-shaped object as a positioning in space. in accordance with. However, the detector can only detect the light-emitting diodes located on the outer surface of the ring-shaped object when viewed from above. That is to say, the light-emitting diodes on the inner surface of the ring-shaped object will be blocked by the ring-shaped object and cannot be detected when viewing from a top view, thus resulting in low tracking effect.

The invention provides a hand-held electronic device, which can provide more accurate optical positioning effect.

The handheld electronic device of the present invention is suitable as a controller of a virtual image display device. The handheld electronic device includes a holding component and a tracking component. The tracking component includes the main body and multiple trackers. The body is connected with the handle component and has an inner surface and an outer surface. The tracker is configured on the inner surface and the outer surface of the body. The tracker arranged on the outer surface and part of the tracker arranged on the inner surface are exposed to the outside in a plan view direction and arranged in a dislocation manner.

Based on the above, in the design of the handheld electronic device of the present invention, the tracker disposed on the outer surface of the main body and part of the tracker disposed on the inner surface of the main body are exposed to the outside in the top view direction and arranged in a misaligned manner. Therefore, compared with the ring-shaped tracking objects in the prior art, the design of the tracking component of the present invention allows the tracker on the inner surface to be easily exposed to the outside and detected by the detector, which can improve the tracker's detection capacity. The measured numbers further enable the handheld electronic device of the present invention to have a more accurate optical positioning effect.
