Variable Repeat Rate Touch Button Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Portable electronic devices with touch-sensitive displays face challenges in efficiently performing repetitive actions on limited screen space, requiring improvements in input control to maintain an effective graphical user interface.
Innovation Solution
A method to control the repeat rate of buttons on touch-sensitive displays by varying the input received, using touch gestures to proportionally adjust the repeat rate, with visual indications on the screen to guide users, allowing for single instance actions or repeated actions dependent on user input.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a touch-sensitive display is used on portable electronic devices, then user input and output efficiency is improved, but controlling repetitive actions on limited screen space becomes difficult
Solution Approach 1:
The repeat rate of the button is made dynamic and adjustable based on user input characteristics. When a user performs a touch gesture with greater speed or distance, the system automatically increases the repeat rate proportionally, allowing flexible control over repetitive actions without requiring separate configuration steps or additional interface elements.
2Productivity
If the repeat rate is increased for faster input, then productivity is improved, but user error increases
Solution Approach 1:
The system provides visual feedback through a visual indication that changes in real-time based on the detected touch gesture characteristics. This feedback loop allows users to monitor and adjust their input to achieve the desired repeat rate, reducing errors by making the system's response predictable and controllable.
3Device complexity
If traditional button repeat control is used, then device complexity is minimized, but ease of operation deteriorates
Solution Approach 1:
The system automatically determines the appropriate repeat rate based on the characteristics of the user's touch gesture itself. The speed and distance of the gesture naturally translate into proportional adjustments of the repeat rate, eliminating the need for separate control mechanisms, configuration menus, or additional interface elements while maintaining ease of operation.

AI summary
A method of controlling a repeat rate of a button displayed on a touch-sensitive display of a portable electronic device is described. In accordance with one embodiment, there is provided a method of operating a touch-sensitive display, comprising: displaying on the touch-sensitive display a user interface screen including a user interface element, the user interface element being activatable by first control input to perform a single instance of an action; when a variable repeat control mode is activated: in response to receipt of a second control input, repeating the action associated with the user interface element at a rate dependent on the second control input; and when the variable repeat control mode is not activated: disabling ability of the second control input to cause the repeating of the action and enabling the first control input to cause a single instance of the action.
