AI Technical Summary

Benefits of technology

Effectively reduces power consumption and prevents unnecessary activation by accurately distinguishing between usage and storage scenarios, thereby conserving energy and extending battery life.

Problems solved by technology

However, the proximity sensor may detect objects such as the case or strap approaching the HMD when the HMD is not in use, thereby causing the electronic display panel to turn on and consume power unnecessarily.

Embodiment Construction

[0019]In the following description of embodiments, numerous specific details are set forth in order to provide more thorough understanding. However, note that the embodiments may be practiced without one or more of these specific details. In other instances, well-known features have not been described in detail to avoid unnecessarily complicating the description.

[0020]Embodiments are described herein with reference to the figures where like reference numbers indicate identical or functionally similar elements. Also in the figures, the left most digits of each reference number corresponds to the figure in which the reference number is first used.

[0021]Embodiments relate to an HMD having magnetic sensors to detect when the HMD is not in use and powering down the HMD when the HMD is not in use. When not in use, the HMD may be packed in a storage case, or a strap attached to a housing of the HMD may be collapsed into the HMD for storage. The magnetic sensor detects a magnet located in t...

Abstract

A head mounted display (HMD) includes a magnetic sensor to produce a sensor signal responsive to detecting a magnet within a first threshold distance. The HMD also includes a circuit operatively coupled to the magnetic sensor. The circuit determines that the HMD is to be placed in a storage mode responsive to receiving the sensor signal from the magnetic sensor. The circuit powers down components of the HMD responsive to determining that the HMD is to be placed in the storage mode.

Description

BACKGROUNDField of the Disclosure[0001]The present disclosure generally relates to a head mounted display, and specifically to powering down of such head mounted display based on magnetic sensor detection.Description of the Related Arts[0002]Virtual reality (VR) systems typically include electronic display panels that present virtual reality images. For example a VR system may include a head mounted display (HMD) that includes an electronic display panel to present VR images to a user. An HMD may include a proximity sensor that detects when the user has put the HMD on. Once the proximity sensor senses that the user has worn the HMD, the electronic display panel turns on. On the other hand, if the proximity sensor senses that the user has taken off the HMD, the electronic display panel is turned off to conserve energy.[0003]HMDs may be stored in cases when not in use. Alternatively, an HMD may include a strap that is worn by a user to secure the HMD on the user's head. When the HMD i...
