Dynamic Input Mode Switching for Mobile User Terminal Devices
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electronic devices, such as navigation systems, often distract users when used while moving, increasing the risk of accidents due to inadequate input methods that do not consider the user's condition or environment.
Innovation Solution
A user terminal device that dynamically switches input modes based on the moving state of the object it is attached to and user profile information, prioritizing voice input over touch or motion inputs in hazardous conditions to maintain user focus on the environment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If multiple input methods (touch, motion, voice) are provided, then user accessibility is improved, but user distraction and safety risk increase when used in moving environments
Solution Approach 1:
The patent dynamically switches between different input modes (touch, motion, voice) based on the detected moving state of the device. When the device is stationary, touch and motion inputs are enabled for full accessibility. When motion is detected indicating the device is being used while moving, the system automatically switches to voice-only input mode, reducing distraction while maintaining operational capability.
Solution Approach 2:
The system changes the operational parameters of the input interface based on the moving state. By detecting acceleration and motion patterns, the system adjusts which input methods are active, transitioning from multiple input methods in stationary conditions to voice-only input when moving, thereby balancing accessibility with safety.
2Ease of operation
If touch and motion input interfaces are enabled, then user interaction capability is improved, but driver safety deteriorates when used while driving
Solution Approach 1:
The input interface dynamically adapts its capabilities based on the detected operating condition. When the device detects that it is being used while driving through motion sensors, it automatically disables touch and motion input methods and enables only voice recognition, thereby maintaining interaction capability while eliminating safety hazards associated with manual input while driving.
Solution Approach 2:
The system extracts and removes the problematic input methods (touch and motion controls) from active use when driving conditions are detected, retaining only the safe voice-based interaction method. This selective removal of dangerous input modalities preserves essential functionality while eliminating safety risks.
3Adaptability or versatility
If input methods do not adapt to user condition and environment, then device functionality is maintained, but user convenience and accessibility deteriorate
Solution Approach 1:
The system continuously monitors the moving state through sensors and uses this feedback to automatically adjust the available input methods. This closed-loop feedback mechanism ensures the interface adapts to the current context (stationary vs. moving), providing optimal convenience and accessibility without requiring manual user configuration.
Solution Approach 2:
The device autonomously determines the appropriate input mode based on its own sensor data without requiring user input or configuration. The system self-adjusts by detecting its own motion state and automatically enabling or disabling specific input methods, making the adaptation process transparent and convenient for the user.
