HMD Image Scaling via Motion Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Head Mounted Device (HMD) type electronic devices face limitations in providing a realistic virtual environment service due to their inability to dynamically adjust images based on user movement, resulting in a less immersive experience.
Innovation Solution
An electronic device equipped with a sensor module to detect movement and a processor that changes the displayed image by searching for and applying image property information, allowing for real-time adjustments in image scale and content based on user movement, thereby enhancing the virtual environment experience.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If HMD provides static 3D images, then device structure is simple, but virtual environment realism is poor
Solution Approach 1:
The patent applies dynamics by transitioning from static 3D images to dynamic image adjustment based on user movement. The processor continuously modifies image scale and content according to real-time movement detection data, creating a dynamic virtual environment that adapts to user actions, thereby improving realism without requiring complex hardware changes.
Solution Approach 2:
The patent implements feedback by using movement detection data to continuously adjust the displayed image. The system detects user movement, processes this information, and modifies the virtual image accordingly, creating a closed-loop system where user actions directly influence the visual output, enhancing the immersive experience.
2Adaptability or versatility
If HMD displays fixed-scale images, then device operation is simple, but user movement responsiveness is poor
Solution Approach 1:
The system transitions from fixed-scale images to dynamic scaling based on movement detection. The processor adjusts image scale in real-time according to detected user movement, enabling the display to adapt to user actions while maintaining operational simplicity through automated processing.
Solution Approach 2:
The patent changes image display parameters (scale, content) based on movement detection data. By dynamically adjusting these parameters according to user movement, the system achieves movement responsiveness without requiring complex manual controls, as the parameter changes are automatically determined by the processing unit.
3Reliability
If HMD uses basic image display, then energy consumption is low, but virtual environment immersion is poor
Solution Approach 1:
The patent applies partial action by selectively adjusting only the necessary image parameters (scale and content) based on detected movement, rather than completely regenerating the entire virtual environment. This approach achieves improved immersion through targeted modifications while minimizing unnecessary energy consumption.
