Touch Panel Button Gray-Out Mechanism for Unintended Input Prevention
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing image processing devices with touch panels often result in unintended operations due to accidental multiple touches at the same position, leading to incorrect selection of buttons, which conventional technologies cannot effectively prevent.
Innovation Solution
An image processing device that disables the specification operation of selection buttons within a predetermined range around the touched coordinates for a set period of time, preventing unintended inputs by making the operation unavailable, such as through a grayed-out indication.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the touch panel allows continuous selection of buttons, then the user can freely change selections, but accidental multiple touches cause unintended operations
Solution Approach 1:
The system performs a preliminary action by disabling the selection function of buttons in the vicinity of the touched position for a predetermined period after detecting a touch operation. This preventive measure is taken before any accidental second touch can occur, thereby eliminating the problem of unintended selections while maintaining normal operation freedom during the disabled period.
2Reliability
If the selection button operation is disabled for a predetermined period, then accidental multiple touches are prevented, but the user cannot quickly change selection
Solution Approach 1:
The disabling effect is applied locally only to buttons within a predetermined range around the touched position, not to the entire screen. This allows users to freely select buttons in other areas of the screen, maintaining operational efficiency while preventing accidental selection of nearby buttons that could cause unintended operations.
3Speed
If the touch panel responds to every touch, then the system is responsive, but wrong operations occur due to accidental touches
Solution Approach 1:
The system applies a preliminary counter-action by disabling the selection function of buttons near the touched position before any harmful accidental operation can occur. This creates a protective effect that prevents wrong operations while maintaining the touch panel's responsive nature, as the system still responds to touches but controls the outcome to prevent errors.

AI summary
A display unit displaying an image and selection buttons on a display screen is provided, and a touch panel in which a desired position on the display screen can be specified is provided on the display unit. Furthermore, a coordinate detection unit and a button processing unit are provided. The coordinate detection unit detects coordinates of a position where a touch operation is performed on the touch panel. The button processing unit operates a tool corresponding to a selection button located at the coordinates and displayed on the display screen and performs a process of disabling a specification operation of a selection button newly displayed in a predetermined range including the coordinates and the vicinity thereof for a predetermined period of time.
