Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current simulation apparatuses face difficulties in simultaneously displaying view screens for multiple directions of a camera's field of view, limiting user ability to identify and adjust the capturable region effectively.
Innovation Solution
The simulation apparatus determines first and second user interface regions based on map and camera performance information, calculating the field of view and maximum working distance to display the camera's capturable range, allowing for simultaneous display of multiple direction views on a single UI screen.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the simulation apparatus displays view screens for multiple directions of camera field of view, then the user ability to identify and adjust capturable region is improved, but the device complexity and calculation complexity increase
Solution Approach 1:
The display screen is divided into multiple UI regions, with each region showing the field of view for a specific camera direction. The determination unit divides the display area into first UI region for map image and second UI region for field of view, allowing simultaneous display of multiple directional views without overwhelming the user with a single complex view.
Solution Approach 2:
The patent overlays the second UI region (field of view) on top of the first UI region (map image), utilizing the z-dimension (layering) to display multiple information layers simultaneously. This allows the field of view to be displayed in relation to the map background without requiring separate full-screen displays for each view.
2Loss of information
If the simulation apparatus calculates and displays field of view and maximum working distance for multiple directions, then the comprehensiveness of camera coverage information is improved, but the calculation complexity and processing time increase
Solution Approach 1:
The determination unit extracts only the essential parameters needed for field of view calculation (camera position, lens focal length, image sensor dimensions) from the camera performance information, and calculates only the maximum working distance rather than the entire coverage area. This selective extraction reduces calculation complexity while maintaining the comprehensiveness of coverage information.
Solution Approach 2:
The patent calculates the field of view based on maximum working distance (the outermost distance from camera to boundary) rather than calculating for every possible distance and angle. This partial calculation approach provides sufficient coverage information without the excessive computational burden of complete geometric analysis.
3Loss of information
If the simulation apparatus displays detailed map information and camera field of view simultaneously, then the information completeness is improved, but the display efficiency and user comprehension speed decrease
Solution Approach 1:
The display is segmented into distinct UI regions: first UI region for map image and second UI region for field of view. This spatial segmentation allows users to quickly locate and process different types of information separately, improving display efficiency and comprehension speed while maintaining information completeness.
Solution Approach 2:
Different regions of the display are assigned different visual characteristics and information densities appropriate to their function. The map region provides geographic context while the field of view region provides camera-specific coverage information, allowing users to process each region according to its local quality and purpose.
