Touch Input System with Symmetrical Indicator Feedback
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional touch input systems lack innovative input operations that provide intuitive and reflective positional feedback, limiting user interaction and engagement, especially in gaming applications where mirrored or symmetrical input reflections can enhance user experience.
Innovation Solution
A touch input system that includes a touch input portion and a display portion where the information processing unit generates an indicator image with a positional relationship in line symmetry or point symmetry to the input position, allowing for innovative input operations by reflecting the input position on the display, enabling users to perform input operations with the input surface turned towards the display.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a conventional touch input system displays input position directly on the touch panel, then the display and input surfaces are integrated, but the user cannot perform input operations with the input surface turned toward the display
Solution Approach 1:
The system separates the display portion and touch input portion into distinct components. The display portion shows the indicator image while the touch input portion receives user input, allowing the input surface to be oriented toward the display without requiring direct integration between input and display areas.
Solution Approach 2:
The system creates a reflected copy of the input position as an indicator image on the display portion. This copied representation allows the user to see feedback on the display while maintaining the ability to orient the input surface toward the display, effectively decoupling the physical input orientation from the visual feedback location.
2Loss of information
If no positional feedback is provided, then the system structure is simple, but the user lacks intuitive understanding of input position and intended touch points
Solution Approach 1:
The system provides immediate visual feedback by displaying an indicator image at a position corresponding to the detected touch input position. This feedback mechanism helps users understand where their input is being registered and what actions will result, reducing information loss without requiring complex additional processing systems.
Solution Approach 2:
The system renders the indicator image with a positional relationship in line symmetry or point symmetry with respect to the input position. This inverted or reflected positioning provides intuitive feedback that mirrors the input action, helping users understand the correspondence between their touch and the resulting display position.
3Measurement precision
If the indicator image is displayed at the exact input position, then the feedback is direct, but the user cannot distinguish between the input surface and display surface positions
Solution Approach 1:
The system deliberately inverts the positional relationship by displaying the indicator image in line symmetry or point symmetry with respect to the input position. This inversion preserves precise position correspondence information while simultaneously providing spatial relationship context that helps users understand the mapping between input and display surfaces.
Solution Approach 2:
The system creates an asymmetric relationship between the input position and indicator image position through reflection symmetry. This asymmetric mapping allows users to distinguish between the physical input location and the visual feedback location while maintaining a mathematically precise correspondence between them.

AI summary
A non-limiting example game system includes a game apparatus which is connected with a television. Furthermore, there is provided with an input terminal device which functions as an input device for the game apparatus. A game screen is displayed on a screen of the television, and a player draws a locus in accordance with a predetermined course from a start to a goal included in the game screen by performing an input operation using the input terminal device. At this time, an inputting surface of a touch panel provided on the input terminal device is turned toward the television. Accordingly, the locus by a slide operation is depicted on the game screen as if the locus is reflected in a mirror.
