Dual-Display HMD Control for Wear Detection and Power Saving
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing head-mounted display devices (HMDs) used for VR, AR, and MR technologies affect user experience due to the need for wearing, limiting interaction and display functionality.
Innovation Solution
Incorporating a first and second display component, where the first is for the wearer and the second is for non-wearers, with adaptive display modes based on detection of wearing status, enabling features like image transmission, wallpaper, parameter, and query displays, and synchronized display states.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a head-mounted display device is worn by a user, then the user can view display content through the first display component, but the user experience is limited and interaction is restricted
Solution Approach 1:
The patent applies multi-functionality by enabling the head-mounted display device to operate in multiple modes: worn mode (first display component active) and non-worn mode (second display component active). The device can function as both a wearable display and a portable screen, allowing users to interact with the device whether worn or held, thereby improving ease of operation while maintaining display versatility
2Loss of information
If the first display component is always on, then the wearer can access display information, but power consumption increases
Solution Approach 1:
The patent implements dynamic display management by automatically switching between the first display component (for wearers) and the second display component (for non-wearers) based on detection of wearing status. This dynamic adaptation ensures display information is always accessible to the appropriate user while minimizing power consumption by activating only the necessary display component at any given time
3Illumination intensity
If the device is designed for wearable use only, then the display effect is optimized for the wearer, but non-wearers cannot interact with or view device information
Solution Approach 1:
The patent segments the display system into two distinct display components: the first display component optimized for the wearer's view when the device is worn, and the second display component visible to non-wearers when the device is held or placed. This segmentation allows each display component to be optimized for its specific viewing context while collectively providing versatile accessibility to both wearers and non-wearers

AI summary
In some aspects, a method for controlling a head-mounted display device is provided. The head-mounted display device may include a first display and a second display. A display mode of the head-mounted display device is obtained. A display state of at least one of the first display or the second display can be controlled based on the display mode. The display mode can include at least one of: a first display mode when a user does not wear the head-mounted display device, or a second display mode when the user wears the head-mounted display device.
