Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If augmented reality techniques are implemented to provide map information and real-world view combination, then user information access and situational awareness are improved, but device complexity increases due to integration of camera module, wireless communication unit, and image processing systems
Solution Approach 1:
The patent combines the camera module, wireless communication unit, and image processing systems into an integrated augmented reality system. The camera captures real-world images, the wireless unit retrieves map data, and the processor merges these elements to display combined augmented reality views, thereby improving information accessibility while managing system complexity through functional integration
Solution Approach 2:
The mobile terminal is designed to perform multiple functions including camera capture, wireless communication for map data retrieval, image processing, and display of augmented reality content. This multi-functional approach allows a single device to provide comprehensive location-based information services without requiring separate specialized devices
2Measurement precision
If real-time camera preview images are processed and combined with map data, then navigation and location-based information are enhanced, but processing time and computational resources increase
Solution Approach 1:
The system pre-loads map data and prepares processing templates before capturing images. By having map information and processing algorithms ready in advance, the system reduces real-time computational burden and accelerates the image processing workflow while maintaining high location information accuracy
Solution Approach 2:
The processor dynamically adjusts processing parameters such as image resolution, map data density, and overlay effects based on the user's location, device capabilities, and processing speed. This adaptive parameter adjustment optimizes the balance between processing time and information accuracy
Data Source
AI summary
A mobile terminal and an operating method thereof are provided. The operating method includes displaying a preview image provided by a camera module on a display module; obtaining position information of the mobile terminal; obtaining a map of an area displayed in the preview image and its relevant areas based on the obtained position information; and displaying an image into which the preview image and the map are combined on the display module. Therefore, it is possible for a user to view a preview image and a map at the same time and determine his or her location with an enhanced sense of reality.
