Touch Control System with Visual Area Indication
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional touch panels fail to notify users of touch valid areas, leading to unintended touch restrictions and power consumption issues due to invalid touch operations on areas other than intended touch valid areas.
Innovation Solution
An electronic apparatus with a detection unit to invalidate touch operations outside specific areas, a control unit to release restrictions upon detecting a predetermined touch operation on those areas, and a display control unit to indicate the specific touch valid areas, allowing users to recognize and interact with them.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If touch operations are restricted to specific areas only, then erroneous operations are prevented, but users cannot recognize where to perform valid touch operations
Solution Approach 1:
The patent applies visual indication (color changes or display differentiation) to highlight valid touch areas on the display screen. When a touch operation is detected in an invalid area, the system displays visual cues that change the appearance of valid touch areas, guiding users to the correct locations for interaction while maintaining the restriction that only those areas accept touch operations.
2Ease of operation
If the display continuously shows valid touch areas, then users can easily recognize them, but power consumption increases
Solution Approach 1:
The patent implements periodic or on-demand display indication rather than continuous display. The visual indication of valid touch areas is activated only when needed - specifically when an invalid touch operation is detected or when the system transitions to a state requiring touch input guidance. This intermittent display approach reduces overall power consumption while maintaining usability when required.
3Stability of the object's composition
If touch restriction is applied to prevent unintended operations, then system stability is improved, but user experience deteriorates due to confusion
Solution Approach 1:
The patent implements a feedback mechanism where the system provides visual information about valid touch areas in response to user interactions. When a touch operation is detected, the system analyzes whether it occurred in a valid area and provides appropriate feedback - either by displaying visual cues indicating where valid areas are located or by providing haptic/visual confirmation. This feedback loop maintains system stability through consistent touch restriction while improving user experience by reducing confusion about where to interact.

AI summary
An electronic apparatus comprises: a detection unit configured to detect a touch operation on a display unit; a control unit configured to control the electronic apparatus, in a touch operation restriction state in which a touch operation on a position different from a specific area on the display unit is invalidated, to release the restriction state and make a transition to a state in which a touch operation on a position different from the specific area is accepted upon detecting a predetermined touch operation on the specific area; and a display control unit configured to control the display unit to perform display to indicate the specific area upon detecting a touch operation on a position different from the specific area on the display unit in the restriction state.
