Radial Gesture Menu for Touchscreen Interface Elements
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional user interface methods on portable devices require multiple steps and selections, which can be cumbersome and prone to errors, especially on small screens, and may lead to increased screen debris and decreased user experience.
Innovation Solution
Implementing a radial menu system where users can perform actions by contacting or hovering over an interface element and swiping in a specific direction to select options, eliminating the need for multiple touch actions and reducing the number of inputs required.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If conventional multi-step interface interaction methods are used, then interface elements can be selected and actions can be performed, but the number of steps required increases user frustration and reduces efficiency
Solution Approach 1:
The patent combines multiple interaction steps into a single continuous gesture. The radial menu system allows users to access multiple functions through one continuous sweeping motion rather than requiring separate taps for each function or menu level. This merging of steps directly addresses the contradiction by reducing interaction complexity while maintaining full functionality.
Solution Approach 2:
The patent introduces a radial dimension to the interface interaction. Instead of linear or hierarchical menu structures requiring multiple taps, the radial menu allows users to access functions by sweeping in different directions from a central point. This dimensional change enables multiple selections to be made within a single interaction sequence, improving productivity without adding steps.
2Ease of operation
If multiple touch actions are required to perform tasks, then interface functionality can be accessed, but screen debris increases and user experience decreases
Solution Approach 1:
By combining multiple selection actions into a single continuous gesture, the radial menu system reduces the frequency of finger-to-screen contacts. Users perform what would traditionally require multiple separate taps in one sweeping motion, thereby reducing oil and debris deposition on the screen while improving ease of operation.
3Area of stationary object
If interface elements are made small to fit on portable device screens, then device portability is maintained, but selection accuracy and ease of use deteriorate
Solution Approach 1:
The radial menu introduces a directional dimension to selection. Instead of relying solely on precise tapping of small elements, users can sweep their finger in different directions from a central point to select functions. This directional approach provides a larger effective target area while maintaining the compact screen size, thereby improving selection accuracy without compromising portability.

AI summary
A user interface (UI) enables a user to access a set of options relating to an element of the UI by contacting a region of a touchscreen, or hovering a feature over the region, associated with that element. Upon contacting or hovering for at least a determined period of time, an arranged set of options is displayed and the user can swipe or move the feature in a specified direction to select a specific option. The options can be the same for each instance of a type of item. When a user learns the direction of one of these options, the user does not have to contact or hover long enough to bring up the menu, but can contact or hover long enough to indicate the element of interest and then perform the appropriate motion, which can cause the action to be performed without first displaying the menu.
