Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The limited battery capacity and processing power of information processing devices, such as augmented reality head-mounted displays, lead to a decrease in display frame rate when the processing demand for virtual objects increases, causing discomfort and disrupting real-time interaction.
Innovation Solution
The device dynamically adjusts the display detail level of virtual objects based on sensed processing capacity, including changing resolution and effect processing, to maintain a stable frame rate by reducing processing load when capacity is exceeded.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If the processing amount of display of the virtual object is increased to improve display quality, then the display detail level is improved, but the display frame rate decreases due to limited processor capacity
Solution Approach 1:
The patent applies dynamics by making the display detail level adjustable and changeable in real-time based on processing capacity conditions. The control unit dynamically modifies display parameters (such as resolution, polygon count, texture quality) of the virtual object according to the current frame rate and processing load, allowing the system to adapt between quality and performance requirements.
Solution Approach 2:
The patent implements parameter changes by modifying display-related parameters of the virtual object (resolution, geometric complexity, texture details, shading quality) based on the detected processing capacity. When the frame rate drops below a threshold, the control unit changes these parameters to reduce processing load, thereby restoring the frame rate while maintaining acceptable display quality.
2Productivity
If the processing capacity is increased to maintain display frame rate, then the display frame rate is maintained, but the power consumption increases reducing battery life
Solution Approach 1:
The patent applies partial action by selectively reducing the display detail level only when and where necessary (when frame rate drops below threshold), rather than maintaining full processing capacity continuously. This allows the system to consume less power during periods when high performance is not needed, while still maintaining acceptable frame rates.
Solution Approach 2:
The patent implements feedback by continuously monitoring the display frame rate and using this information to adjust the processing load. The control unit detects the frame rate, compares it with a predetermined threshold, and adjusts the display parameters accordingly, creating a closed-loop control system that optimizes power consumption based on actual performance needs.
3Productivity
If the display detail level is reduced to maintain frame rate, then the display frame rate is maintained, but the display quality deteriorates
Solution Approach 1:
The system dynamically adjusts display parameters based on real-time processing capacity assessment, allowing the display quality to be optimized for current conditions rather than being fixed. This enables the system to maintain high quality when processing capacity allows and reduce quality only when necessary to maintain frame rate.
Solution Approach 2:
The patent changes display parameters (resolution, geometry complexity, texture quality, shading details) based on processing capacity conditions. These parameter changes are designed to reduce processing load while minimizing the impact on perceived display quality, maintaining an optimal balance between frame rate and visual fidelity.
