Eye Tracking Based VR Scene Modification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
As the field of view of virtual reality and augmented reality head mount displays increases, the space for dynamic changes in virtual scenes decreases, leading to potential disruption of the immersive experience for users.
Innovation Solution
A method and apparatus that utilize eye tracking data to determine a user's gaze area and modify scene data in non-gaze areas or areas within a preset range around the gaze area, ensuring dynamic modifications are made in a hidden state to maintain immersion.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the field of view of head mount displays is increased to improve immersion, then the immersive experience is improved, but the space available for dynamic scene changes decreases
Solution Approach 1:
The patent applies local quality by making different regions of the virtual scene have different modification characteristics. The scene is divided into a first region (where the user is gazing) and a second region (non-gazed area), with the second region allowing dynamic modifications while the first region maintains stability. This spatial differentiation resolves the contradiction by enabling scene changes only in areas where they will not be perceived by the user.
2Quantity of substance
If scene information is updated or added in the virtual scene, then the scene content is enriched, but the user's sense of immersion is broken due to detectable changes
Solution Approach 1:
The patent implements dynamics by making the scene modifiable based on real-time eye tracking data. The system dynamically determines whether a region is gazed or non-gazed and adjusts the modifiability of scene elements accordingly. This temporal and spatial dynamic control allows scene information to be updated only when and where the user is not looking, preventing immersion breaks while still enriching scene content.
3Productivity
If dynamic changes are made in the gaze area, then the scene can be updated in the user's field of view, but the user may discover the changes and break immersion
Solution Approach 1:
The patent applies preliminary action by using eye tracking to predict where the user is looking and proactively determining which regions are safe for modification before making changes. The system performs preliminary assessment of gaze data to identify non-gazed regions, then updates scene information in those areas. This prevents immersion breaks by ensuring changes occur only in areas the user is not currently observing.

AI summary
The present disclosure relates to a dynamic changing method and apparatus for a virtual reality scene, and an electronic device, which relate to the technical field of virtual reality. The dynamic changing method for the virtual reality scene comprises: acquiring eye tracking data of a user; acquiring a gaze area of the user in the virtual reality scene according to the eye tracking data; determining a scene modifiable area according to the gaze area; and modifying the scene data of the scene modifiable area.
