Dynamic Virtual Object Resolution for VR Display Load Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Information processing apparatuses face increased drawing loads and resource demands when expressing objects in a more realistic manner, leading to reduced display frame rates, increased processor resource usage, and power consumption, particularly when users are in motion.
Innovation Solution
An information processing apparatus that acquires motion information from users and adjusts the image quality of virtual objects based on this information, reducing resolution when the user is in motion to control display loads and maintain realistic expressions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If image quality of virtual objects is maintained at high resolution, then realistic visual expression is achieved, but drawing loads increase and frame rate decreases
Solution Approach 1:
The patent applies dynamics by making the image quality of virtual objects adjustable based on user motion state. The system dynamically switches between high resolution (when user is stationary) and low resolution (when user is moving), allowing the display parameters to adapt to real-time conditions rather than remaining static
Solution Approach 2:
The patent changes the resolution parameter of virtual objects based on detected motion information. When motion is detected, the system reduces the resolution parameter from high to low, directly addressing the contradiction by modifying key parameters to balance visual quality and processing performance
2Manufacturing precision
If image quality of virtual objects is maintained at high resolution, then realistic visual expression is achieved, but processor resource usage increases and heat generation occurs
Solution Approach 1:
The system dynamically adjusts processing demands by changing image quality based on motion state. When user motion is detected, the system reduces processing requirements by lowering resolution, thereby reducing processor workload and heat generation while maintaining acceptable visual quality during movement
Solution Approach 2:
The patent modifies the resolution parameter to control processor resource consumption and heat generation. By switching from high to low resolution based on motion detection, the system directly manages thermal output and resource usage to prevent overheating during active use
3Manufacturing precision
If image quality of virtual objects is maintained at high resolution, then realistic visual expression is achieved, but power consumption increases
Solution Approach 1:
The patent implements dynamic power management by adjusting image quality according to motion state. The system maintains high power consumption only when necessary (user stationary and high quality needed), and reduces power consumption when user is moving, optimizing energy usage based on actual display requirements
Solution Approach 2:
The system changes the resolution parameter to control power consumption. By reducing resolution from high to low based on detected motion, the patent directly manages energy consumption to extend battery life while maintaining acceptable visual quality during motion

AI summary
An information processing apparatus 1 acquires motion information regarding a user 700 who is a user, determines the image quality (for example, the resolution) of a virtual object on the basis of the acquired motion information, and controls the display of the virtual object on the basis of the determined image quality. The virtual object is displayed with low resolution, for example, when the user 700 is turning his/her head. On the other hand, the virtual object is displayed with high resolution when the user 700 is put in a stationary state, that is, when a change becomes zero. The information processing apparatus 1 makes it possible to reduce a drawing load, while maintaining a real expression.
