Dynamic Virtual Adjusting Button Scaling for Precision
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The downsizing of electronic devices makes virtual adjusting buttons difficult to control due to their small size on the screen, leading to challenges in identifying scale counts and adjusting settings with precision.
Innovation Solution
A method that dynamically scales up or down the size of a virtual adjusting button based on the distance between an operating point and a reference point, allowing for increased precision in setting adjustments by changing the number of scale graduations displayed.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If the screen size is scaled down to make electronic devices slimmer and more compact, then the portability and compactness of the device is improved, but the size of the virtual adjusting button decreases making it difficult to control with precision
Solution Approach 1:
The virtual adjusting button dynamically changes its displaying size based on the distance between the operating point and the reference point. When the operating point moves away from the reference point, the button scales up to provide more visible scale graduations for precise adjustment. When the operating point moves closer, the button scales down to maintain a clean interface. This dynamic adaptation resolves the contradiction by making the button size variable rather than fixed.
Solution Approach 2:
The patent changes the displaying size parameter of the virtual adjusting button based on the distance parameter from the reference point. By using different size parameters at different distances, the system provides both compactness (when close) and precision (when far), resolving the contradiction between device compactness and adjustment precision.
2Measurement precision
If the virtual adjusting button is made larger to improve control precision, then the adjustment precision is improved, but the available screen space decreases and the interface becomes cluttered
Solution Approach 1:
The virtual adjusting button transitions from a static size to a dynamic size that adapts to user interaction. The button remains compact during normal display to preserve screen space, but expands when the user needs to perform precise adjustments by moving the operating point away from the reference point. This dynamic behavior resolves the contradiction between precision and screen space utilization.
3Loss of information
If fixed scale graduations are added to the virtual adjusting button to improve identification, then the scale identification is improved, but the button size increases and precision control becomes more difficult
Solution Approach 1:
The patent applies different visual qualities to different parts of the virtual adjusting button based on the operating point's position. When the operating point is far from the reference point, more scale graduations are displayed with higher visibility. When close, fewer graduations are shown to maintain control precision. This local adaptation of information density resolves the contradiction between scale identification and control precision.

AI summary
A method for operating a virtual adjusting button is provided. A virtual adjusting button is displayed. The virtual adjusting button is operated by an operating point of an operating unit for adjusting a setting value correspondingly. A movement of the operating point is detected when the operating point is located on the virtual adjusting button and the virtual adjusting button is selected. A dynamic virtual adjusting button corresponding to the virtual adjusting button is displayed with the movement of the operating point when detecting that the operating point moves toward a direction away from or close to a reference point of the virtual adjusting button. A displaying size of the dynamic virtual adjusting button is changed correspondingly with a change of a distance between the operating point and the reference point. A precision of the setting value for adjusting is changed by operating the dynamic virtual adjusting button.
