External Display Mediator for VR Position Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing virtual reality glasses systems do not allow for simple external influence on the content displayed, limiting the ability of non-wearers to adjust the viewing position of virtual objects for wearers.
Innovation Solution
A method and system that enables external influence on virtual reality glasses by displaying virtual objects and position symbols on an external display unit, allowing users to perform virtual position changes by confirming actions on these symbols, which adjusts the viewing position of virtual objects displayed on the glasses.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If virtual reality glasses are used to display virtual objects, then the wearer has an immersive experience with large displayed image areas, but external persons cannot easily influence or adjust the displayed content
Solution Approach 1:
The patent introduces an external display unit as an intermediary device that shows position symbols representing different virtual viewing positions. This mediator allows external persons to select and communicate position changes to the wearer without directly controlling the VR glasses, thus enabling external influence while maintaining operational simplicity through an intuitive visual interface.
Solution Approach 2:
The external display unit creates a visual copy or representation of the virtual viewing positions through position symbols that correspond to actual positions in the virtual environment. This copying mechanism allows external persons to interact with a simplified representation rather than the complex VR system directly, enabling easy selection and communication of position changes.
2Adaptability or versatility
If the wearer moves to different virtual viewing positions, then diverse viewing angles of virtual objects are achieved, but the system becomes more complex requiring position tracking and coordinate transformations
Solution Approach 1:
The patent extracts the position selection function from the VR glasses themselves and places it on an external display unit. The external device handles the complexity of position tracking and coordinate transformations, while the VR glasses simply execute the selected position changes. This separation reduces the complexity burden on the wearable device.
Solution Approach 2:
The external display unit acts as a mediator that manages the complexity of position tracking and coordinate transformations. It displays position symbols that represent different viewing positions and processes the selection input, then communicates the desired position change to the VR system, shielding the wearer from the underlying complexity.
3Ease of operation
If position symbols are displayed on an external device, then non-wearers can easily select viewing positions, but additional hardware and synchronization between devices are required
Solution Approach 1:
The external display unit serves multiple functions: it displays position symbols for selection, provides visual feedback about current and target positions, and communicates with the VR system. This multi-functionality consolidates several requirements into a single device, reducing overall system complexity despite the added hardware.

AI summary
A method for operating virtual reality glasses involves displaying at least one virtual object from a first virtual viewing position by the virtual reality glasses and displaying the virtual object and a first position symbol at a point corresponding to the first virtual viewing position and at least one further position symbol at a point corresponding to a further virtual viewing position by an external display unit. If a predetermined confirmation action in relation to the further position symbol displayed on the display unit has been detected, a virtual position change is performed by the virtual reality glasses from the first virtual viewing position to the further virtual viewing position, whereupon the virtual object is displayed from the further virtual viewing position by the virtual reality glasses.
