Touch Panel Cancel Button for Cleaning Disablement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional touch panel systems do not allow users to cancel input reception disablement at any timing, leading to inconvenience during cleaning, as all inputs are disabled simultaneously.
Innovation Solution
An information processing apparatus with a touch panel that displays a cancel button for disabling input reception, measuring depression time and position to enable cancellation only under specific conditions, and optionally making the button transparent or changing its position to prevent accidental cancellation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If input reception of the touch panel is disabled for a predetermined time during cleaning, then smears on the screen become more conspicuous and workability during cleaning is improved, but users cannot cancel the disablement at any timing which leads to inconvenience
Solution Approach 1:
The system dynamically changes the touch panel's input reception state between enabled and disabled modes. The cancel button provides a dynamic exit mechanism that allows users to transition from the disabled state back to the enabled state at any timing, resolving the contradiction between maintaining disablement for cleaning purposes and allowing flexibility for users who need to restore input reception earlier than the predetermined time expires.
2Ease of operation
If a cancel button is displayed to allow cancellation of disablement, then users can cancel at any timing improving convenience, but accidental cancellation may occur reducing reliability
Solution Approach 1:
The system requires the user to perform a preliminary action of pressing the cancel button before the actual cancellation occurs. This preliminary pressing action serves as a confirmation step that distinguishes intentional cancellation from accidental touches, thereby maintaining reliability while preserving the convenience of on-demand cancellation.
Solution Approach 2:
The system changes the operational parameters of the cancel button by requiring a prolonged press duration exceeding a threshold value. This parameter change transforms the button from a simple single-tap response to a duration-based activation mechanism, effectively preventing accidental cancellations while maintaining intentional ones.
3Ease of manufacture
If the cancel button is made transparent or position is changed, then smear detection on the touch panel is facilitated, but the button may become harder to locate reducing ease of operation
Solution Approach 1:
The cancel button's visual properties are dynamically adjusted based on the operational state of the touch panel. When the touch panel is in disabled mode, the cancel button becomes visible or changes position to guide users to the cancellation mechanism. When the touch panel is enabled or during active cleaning, the button becomes transparent or moves to minimize interference with smear detection, thus resolving the contradiction between visibility for operation and transparency for inspection.

AI summary
An information processing apparatus includes circuitry; and a memory storing computer-executable instructions that cause the circuitry to execute displaying, on a touch panel, a cancel button for canceling disablement of input reception of the touch panel; measuring a depression time during which the cancel button is pressed by a user; detecting a depression position at which the cancel button is pressed by the user; and cancelling the disablement in response to detecting that the depression time is longer than a cancel depression time defined in advance and that the depression position is continuously located at the same position.
