Virtual Reality Glasses Position Detection for External Display Synchronization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods fail to determine when to synchronize the image displayed by virtual reality glasses with an external display device, ensuring that the image is only shown when the user is wearing the glasses and within a specific region, to maintain relevance and accuracy.
Innovation Solution
A method that continuously detects the position of virtual reality glasses using infrared light or contact-sensitive sensors to determine if they are within a specified region, activating the external display device only when the glasses are worn and within this region, and hiding the image when the glasses are removed.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the image displayed by virtual reality glasses is continuously displayed on an external display device, then the visibility for multiple observers is improved, but the relevance and accuracy of the displayed image deteriorates when the user removes the glasses
Solution Approach 1:
The system continuously detects the position of virtual reality glasses using infrared light sources and sensors, and uses this feedback information to control the external display device. When glasses are detected within the specified region, the external display shows the virtual reality image; when removed, the display is deactivated or shows alternative content, ensuring relevance while enabling multi-observer visibility when appropriate
Solution Approach 2:
The patent introduces an intermediary control system that mediates between the virtual reality glasses and the external display device. This intermediary uses position detection technology (infrared sensors detecting light sources on the glasses) to determine whether to activate the external display, resolving the contradiction by making the external display's operation conditional rather than continuous
2Ease of operation
If the external display device is activated to show the virtual reality image, then the accessibility for other observers is improved, but the energy consumption and unnecessary display increase when the glasses are not in use
Solution Approach 1:
The external display device transitions from a static on/off state to a dynamic state that continuously adapts based on the detected position of the virtual reality glasses. The display activation is dynamically controlled - enabled when glasses are within the specified region and disabled when removed - optimizing energy consumption while maintaining accessibility when needed
Solution Approach 2:
The system uses real-time position feedback from infrared sensors to control the power state of the external display device. This feedback mechanism ensures the display consumes energy only when necessary (when the user is wearing the glasses and within the specified region), eliminating wasteful energy consumption during periods when the virtual reality content is not being viewed

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Ensures that the image displayed on the external device is relevant and synchronized with the user's view, providing a seamless and realistic virtual reality experience while preventing unnecessary display when the glasses are not in use.
Implementation Method 1
it is provided that infrared light is emitted by an infrared light source disposed on the virtual reality glasses, especially two infrared LEDs, wherein the position of the virtual reality glasses is determined by a detecting device using the infrared light detected by the same
Data Source
AI summary
A method for operating a display device Involves displaying at least one virtual object from a virtual observation position by virtual reality glasses, continuously detecting a position of the virtual reality glasses, determining, using the continuously detected position of the virtual reality glasses, whether the glasses are disposed in a specified region, and displaying the virtual object from the same virtual observation position by means of the display device as long as the virtual reality glasses are disposed in the specified region. A system includes virtual reality glasses.
