Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current mobile head-mounted display units lack efficient location-based and orientation-based image rendering capabilities, which limits their ability to provide contextually relevant and augmented reality images to users in real-time, especially in dynamic environments.
Innovation Solution
A mobile computing system that includes a head-mounted display unit (HMD) and a network-based component, which uses location and orientation data to render location-based and augmented images by processing GPS coordinates and physical orientation, leveraging wireless communication and image processing modules to provide real-time, context-specific content.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If location-based image rendering is implemented in real-time, then the relevance and contextual accuracy of displayed images is improved, but the processing time and computational complexity increase
Solution Approach 1:
The system pre-processes and stores location-based image data in advance, so that when location data is received, the appropriate images are already prepared and can be displayed with minimal additional processing time, resolving the contradiction between rendering precision and processing time
Solution Approach 2:
A database serves as an intermediary between the location data and the image rendering process, storing pre-processed location-image mappings that enable fast retrieval and display without real-time computational complexity
2Adaptability or versatility
If augmented reality images are displayed in dynamic environments, then the user experience and contextual relevance are improved, but the device complexity and system requirements increase
Solution Approach 1:
The system uses a universal database structure and processing framework that can handle multiple types of location-based and augmented reality images through the same mechanisms, reducing the need for separate specialized systems for different display scenarios
Solution Approach 2:
The system creates virtual copies of real-world locations with augmented image data, allowing dynamic environment adaptation without requiring complex real-time processing of actual environmental conditions
3Productivity
If real-time location-based content is provided, then the responsiveness and user engagement are improved, but the energy consumption and data processing load increase
Solution Approach 1:
Location-based image data is pre-processed and stored in a database before actual display is needed, so that real-time content delivery involves only data retrieval rather than computationally intensive image generation, reducing energy consumption while maintaining responsiveness
Solution Approach 2:
The system replaces complex real-time image processing mechanisms with simpler data retrieval operations from pre-processed databases, reducing the computational energy required for content delivery while maintaining real-time responsiveness
