Virtual Reality Spectacles Viewpoint Selection Method
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Virtual reality spectacles often cause nausea due to inconsistencies between visual impressions and vestibular feedback during free movements, and users struggle to gauge changes in their line of vision within virtual surroundings.
Innovation Solution
A method for virtual reality spectacles that allows users to select and confirm position symbols to change their viewpoint, displaying a standard line of vision to prevent nausea by enabling controlled and intuitive movement between predefined observation positions, using sensors to track head or eye movements for selection and control.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If free movements are allowed within virtual reality surroundings, then the user can explore the virtual environment freely, but nausea occurs due to inconsistency between visual impressions and vestibular feedback
Solution Approach 1:
The continuous free movement is segmented into discrete predefined observation positions. Users can move between specific designated locations rather than freely anywhere, which maintains exploration capability while preventing motion sickness by aligning visual movements with vestibular system expectations.
Solution Approach 2:
The system pre-defines multiple observation positions before the user needs to move. These positions are prepared in advance with their corresponding visual and spatial parameters, allowing the user to transition between them without continuous motion, thus avoiding the nausea caused by uncontrolled movement.
2Ease of operation
If the user moves continuously through virtual surroundings, then the user can change observation positions freely, but the user cannot accurately gauge changes in line of vision to virtual objects
Solution Approach 1:
The system provides explicit visual feedback in the form of position symbols that appear at predefined observation positions. When the user activates a position symbol, the system displays a standard line of vision indicator that clearly shows the user's new line of vision to virtual objects, providing immediate and accurate feedback about the change in observation position.
Solution Approach 2:
The system pre-calculates and displays the standard line of vision for each predefined observation position before the user actually moves to it. This allows the user to understand in advance what their line of vision will be like at each position, eliminating uncertainty about spatial orientation.
3Ease of operation
If predefined observation positions are provided with visual indicators, then the user can clearly see position options, but the system complexity increases
Solution Approach 1:
The system uses simple visual indicators such as position symbols with distinct colors or patterns that appear at predefined observation positions. These color-coded markers provide clear visual information about available positions without requiring complex interfaces or additional hardware, maintaining ease of operation while managing system complexity.

AI summary
A method for operating virtual reality spectacles, having the steps of: display of at least one virtual object, arranged in virtual surroundings, by means of the virtual reality spectacles from a first observation position that is prescribed within the virtual surroundings; display of at least one position symbol at a position within the virtual surroundings that corresponds to a second observation position prescribed within the virtual surroundings; identification of a virtual standard line of vision to the virtual object from the second observation position; selection of the displayed position symbol as soon as a predetermined selection action has been sensed; and display of the virtual object from the second observation position as soon as a predetermined confirmation action for the selected position symbol has been sensed. Furthermore, the invention relates to a system having virtual reality spectacles.
