Mobile Terminal Touch Trajectory Recognition for Edge Operability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Mobile terminal devices face low operability due to small operation images displayed at the edge of the screen, making touch operations cumbersome, especially on devices with limited display area.
Innovation Solution
A mobile terminal device with a display unit showing an image of an operation unit, a detecting unit to track touch operations, and a control unit that changes the image based on the touch trajectory, allowing operations to be recognized even when performed outside the primary display area, thereby enhancing user interaction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If the operation image is displayed at the edge of the display area, then the display area for content is maximized, but the operability of touch operations deteriorates
Solution Approach 1:
The patent extends the operation recognition from a two-dimensional small image area at the edge to the entire display screen by recognizing touch trajectories across the full display area. This dimensional expansion allows users to perform operations anywhere on the screen while maintaining full content display area.
Solution Approach 2:
The display screen serves multiple functions: it displays content information and simultaneously serves as the entire operation area. The operation image is not just a visual indicator but defines the complete interaction space, allowing the screen to function both as information display and control interface.
2Area of stationary object
If the operation image is made small to fit the display, then the display area is maximized, but the ease of operation deteriorates
Solution Approach 1:
The patent transforms the operation area from a small localized image to the entire display screen by utilizing touch trajectory recognition. This allows the operation space to expand dimensionally across the full display area while keeping the operation image small for content display purposes.
3Device complexity
If the operation image is displayed in a limited area, then the device complexity is reduced, but the ease of operation deteriorates
Solution Approach 1:
The touch panel serves dual purposes: it displays the operation image and simultaneously recognizes operations performed anywhere on its surface through trajectory detection. This multi-functionality eliminates the need for separate operation areas while maintaining simplicity in the display structure.
Solution Approach 2:
The operation image itself serves as the operation area by defining the interaction space. The trajectory recognition system uses the displayed image coordinates to interpret touch operations, allowing the image to self-define its functional area without requiring additional structural elements.

AI summary
A mobile terminal device, method, and program that displays, on a display unit, an image indicating an operation unit corresponding to a physical operation unit and used to navigate in place of the physical operation unit, detects a touch operation performed on the display unit, and changes the image indicating the operation unit according to a trajectory of the touch operation.
