Wearable Interface Control via Dynamic Input Adaptation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wearable device control systems are limited by requiring fixed input actions, which can be difficult for users to perform when both hands are occupied or in cramped spaces, restricting the ability to input information effectively.
Innovation Solution
A wearable user interface control system that includes an input action setting unit and an input accepting unit, which selects and sets an appropriate input action based on the user's environment and working actions, allowing for flexible input methods such as head or arm movements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a fixed input action (such as finger operation on keyboard image or predetermined gesture) is used in wearable device control, then the system structure can be simple, but the ease of operation deteriorates when both hands are occupied or in cramped spaces
Solution Approach 1:
The input action is changed from a fixed predetermined gesture to a dynamic action that adapts to the user's current state. The system detects whether the user is wearing gloves and automatically adjusts the input method - using voice recognition when gloves are detected, and gesture recognition when they are not. This dynamic adaptation resolves the contradiction by making the system easy to operate in various conditions without requiring complex manual configuration.
Solution Approach 2:
The system automatically detects the user's environment (glove wearing status) and selects the appropriate input method without user intervention. The wearable device itself performs the adaptation by monitoring sensor data and switching between input modes, eliminating the need for the user to manually change settings or choose input methods, thus improving ease of operation.
2Adaptability or versatility
If multiple input actions are provided for selection, then the adaptability to different environments improves, but the device complexity increases
Solution Approach 1:
The wearable device incorporates multiple input capabilities (voice recognition and gesture recognition) within a single unified system. Rather than requiring separate devices or complex configuration, the system provides universal input functionality that adapts to different user needs and environments. This multi-functionality is achieved through integrated sensors and processing that can handle both voice and gesture inputs, resolving the contradiction between adaptability and complexity.
Solution Approach 2:
The system changes the operational parameters (input method) based on detected environmental conditions (glove wearing status). By monitoring the state of the user and adjusting the input mode accordingly, the system achieves high adaptability to different conditions while maintaining a relatively simple structure through automated parameter adjustment rather than complex user-configurable options.

AI summary
An input action setting unit selects an action of a user to be accepted as an input operation. An input accepting unit accepts an output from a sensor that is worn by a user and detects a movement of at least one region of the user. When detecting based on the output of the sensor that the user has performed the action selected by the input action setting unit, the input accepting unit accepts the action as an input operation performed by the user. The input action setting unit selects an action of the user to be accepted as the input operation from among preset multiple kinds of action of the user based on at least one of an environment in which the user is placed and a working action of the user other than the input operation, and sets the action in the input accepting unit.
