Solution Overview
Problem
Virtual reality (VR) headsets face challenges in meeting stringent performance requirements such as resolution and refresh rate due to the characteristics of conventional displays, which are not ideal for VR applications.
Innovation Solution
A VR system with a display that includes a dual-row driver configuration, eye tracking, and selective scaling circuitry to adjust the resolution dynamically based on user gaze direction, allowing for regions of the display to operate in full or reduced resolution, thereby optimizing bandwidth usage without compromising image quality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If the display operates at full resolution across the entire screen, then image quality is maintained, but bandwidth requirements increase significantly
Solution Approach 1:
The patent applies local quality by differentiating resolution across different regions of the display. A first region (e.g., central area) operates at full resolution to maintain image quality for the user's focal point, while a second region (e.g., peripheral areas) operates at reduced resolution to decrease bandwidth requirements. This spatial differentiation of quality levels directly resolves the contradiction between maintaining image quality and reducing bandwidth.
Solution Approach 2:
The display is segmented into multiple resolution regions based on gaze direction. The system divides the display screen into a first region for full resolution and a second region for reduced resolution, allowing independent control of resolution characteristics in different segments. This segmentation enables the system to optimize bandwidth while maintaining quality where needed.
2Productivity
If the display uses conventional characteristics, then device complexity is low, but performance requirements for resolution and refresh rate are not met
Solution Approach 1:
The patent implements dynamics by making the display resolution configurable based on real-time gaze detection. The system dynamically switches between full resolution and reduced resolution modes in different regions of the display, allowing the display characteristics to adapt to current usage requirements. This dynamic adjustment enables the system to meet performance requirements when needed while maintaining lower complexity during reduced resolution operation.
Solution Approach 2:
The system changes the resolution parameter dynamically based on gaze direction and user focus. By modifying the resolution setting from full to reduced in specific regions, the system optimizes performance for critical visual areas while reducing overall bandwidth consumption. This parameter change strategy allows the display to meet stringent VR performance requirements without requiring the entire display to operate at maximum complexity.
3Adaptability or versatility
If the resolution region is fixed, then device complexity is reduced, but adaptability to user gaze direction is lost
Solution Approach 1:
The patent employs feedback by continuously monitoring gaze direction and using this information to dynamically adjust the resolution configuration of the display regions. The system receives gaze data, determines the user's focal point, and accordingly configures which regions operate at full versus reduced resolution. This feedback loop enables high adaptability to user behavior while managing complexity through automated, algorithm-based decision making.
Data Source
AI summary
A virtual reality system and a display device that can be used, for example, as part of the virtual reality system. The display device can have more than one data driver, such as an even row data driver and an odd row data driver. The display device can have a configurable resolution such that one region of the display device operates at full resolution while another region of the display device operates at a reduced resolution. The virtual reality system can also track an eye gaze and adjust the full resolution region of the display device to track the eye gaze.
