VR Video Playback Resumption Using Recorded Gaze Position
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing VR technologies fail to maintain the user's view point continuity during transitions between pass-through and video playback, leading to potential missed content.
Innovation Solution
An information processing apparatus equipped with a gaze acquisition unit to record gaze information during video pause, allowing seamless video resumption based on recorded gaze data.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the video is stopped during pass-through function, then the user can check the real space scene, but the viewpoint changes and critical video content may be missed
Solution Approach 1:
The system performs preliminary actions by recording the viewpoint information and video playback position before the pass-through function is activated. This allows the system to restore the exact previous state after pass-through, preventing any loss of video content while still allowing the user to check the real space scene.
Solution Approach 2:
The system creates a copy of the viewpoint information and playback position data before pausing the video. This copy is stored and used to restore the original viewing state after pass-through, ensuring that no video content is missed while enabling the adaptability of the pass-through function.
2Ease of operation
If the viewpoint is automatically changed according to HMD movement, then the user experience is enhanced, but the video playback position becomes inconsistent with user expectations
Solution Approach 1:
The system records the playback position and viewpoint information before automatic viewpoint changes are applied. When the pass-through ends, the system restores the original playback position and viewpoint, ensuring reliability and consistency with user expectations while still allowing ease of operation during normal viewing.
3Ease of operation
If the video is automatically resumed after pass-through, then convenience is improved, but the video may resume at an incorrect viewpoint
Solution Approach 1:
The system creates and stores a copy of the original viewpoint information and playback position before pausing. When resuming the video automatically after pass-through, this copied data is used to restore the exact original viewpoint and position, ensuring both convenience and measurement precision in the resumption process.
