Ring Menu Interface for Arm Rotation Input
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Information processing apparatuses are difficult for users with limited mobility or dexterity to control due to complex and precise input operations, especially for those with medical conditions like arthritis, making it hard to access menus and perform tasks.
Innovation Solution
An information processing apparatus with a user interface that displays items in a ring, allowing users to select items by rotating their arm, with the system analyzing the rotation to update the interface and highlight options, reducing the complexity of input operations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional input operations are used, then precise control is achieved, but ease of operation deteriorates for users with limited mobility
Solution Approach 1:
The patent changes the parameter of input method from fine motor finger movements to gross motor arm rotations. The system detects arm rotation angle and uses it to control menu navigation, allowing users with limited hand dexterity to operate the device through larger, more manageable arm movements while maintaining sufficient precision for selection.
Solution Approach 2:
The patent replaces the mechanical finger-based input system with an optical/electronic arm rotation detection system. Sensors detect arm rotation and convert it into digital signals for menu navigation, substituting the need for precise manual dexterity with a more accessible movement-based interface.
2Adaptability or versatility
If complex input operations are required, then functionality is comprehensive, but device complexity increases
Solution Approach 1:
The patent creates a universal input mechanism that can handle multiple functions (menu navigation, selection, scrolling) through a single arm rotation gesture. This multi-functional approach reduces the need for multiple specialized controls, simplifying the overall input system while maintaining comprehensive functionality.
Solution Approach 2:
The patent extracts the essential control function from complex multi-button interfaces and condenses it into a single arm rotation input. By taking out only the necessary rotational movement and mapping it to menu navigation, the system reduces input complexity while preserving access to all functions.
