Annular Knob Interface for Electronic Device Interaction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional human machine interfaces are not designed to effectively utilize knob switches, limiting user interaction and experience compared to keyboard or touchpad interfaces.
Innovation Solution
A control method for an electronic device that includes a screen and a knob module, where a trigger signal enables the knob module, and an operating interface with annularly arranged functional regions is displayed on the screen, allowing users to switch and select options using input signals from the knob module.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional human machine interfaces (keyboard or touchpad) are used, then the interface design is straightforward, but the user interaction diversity and experience are limited
Solution Approach 1:
The interface is segmented into multiple annular functional regions, each representing different function options. This segmentation allows the knob switch to interact with distinct zones for different operations, enhancing interaction diversity while maintaining clear visual organization and manageable complexity
Solution Approach 2:
The interface transitions from traditional flat 2D layout to an annular/circular dimension that matches the knob switch's rotational motion. This dimensional change enables natural mapping between physical knob rotation and interface navigation, improving adaptability without significantly increasing design complexity
2Ease of operation
If a knob module is implemented without a dedicated operating interface, then the device structure remains simple, but the knob switch functionality is limited and user experience deteriorates
Solution Approach 1:
The annular operating interface serves multiple functions: displaying function options, indicating selection state through marking, and providing visual feedback during rotation. This multi-functional design enhances knob usability without requiring separate components, maintaining relatively simple device structure
Solution Approach 2:
The interface provides real-time visual feedback by marking the currently selected functional region and updating display content according to knob position. This feedback mechanism significantly improves ease of operation by allowing users to see their selection state and make informed decisions
3Loss of information
If multiple function options are displayed without clear visual indication, then the interface information density is high, but the user cannot easily identify the selected option
Solution Approach 1:
The interface uses marking indicators (such as highlighted colors or visual emphasis) to distinguish the selected functional region from others. This visual differentiation ensures users can easily identify the selected option among multiple functions without increasing overall display structure complexity

AI summary
A control method is provided, applied to an electronic device. The electronic device includes a screen and a knob module. The control method includes: receiving a trigger signal to enable the knob module, and displaying an operating interface corresponding to the knob module on the screen according to the trigger signal, where the operating interface includes a plurality of functional regions that is arranged annularly, and the functional regions are configured to display a plurality of function options, where one of the functional regions shows a marked state; switching the functional region corresponding to the marked state according to a first input signal from the knob module; and selecting the functional region corresponding to the marked state according to a second input signal from the knob module.
