Touch Mode User Terminal for Visual Distraction Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing navigation devices in vehicles require users to visually interact with the screen while driving, leading to a high risk of accidents due to the distraction, and there is a need for a method to mitigate this risk while enhancing user convenience.
Innovation Solution
A user terminal system that allows users to manipulate a User Interface (UI) screen without visually watching it by using a touch mode where touch manipulations, such as the number of touch points and gestures, are translated into commands to navigate menu items on an external apparatus, enabling remote control of the UI screen.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If users visually interact with the navigation screen while driving, then users can accurately manipulate the UI screen, but the risk of car accidents increases due to visual distraction
Solution Approach 1:
The patent introduces a mobile terminal as an intermediary device between the user and the navigation system. The mobile terminal provides a touch interface that can be operated without visual attention, acting as a mediator that transfers control commands to the navigation system while keeping the user's eyes on the road.
Solution Approach 2:
The patent replaces the traditional visual-mechanical interaction (watching and touching the navigation screen) with a tactile-auditory system. Users receive audio feedback and tactile responses from the mobile terminal, substituting the need for visual confirmation during UI manipulation.
2Object-affected harmful factors
If users do not watch the UI screen while manipulating it, then visual distraction risk is reduced, but the precision of touch manipulation decreases
Solution Approach 1:
The patent implements audio feedback mechanisms that provide real-time information about the current menu state and selection status. This auditory feedback compensates for the lack of visual feedback, allowing users to accurately manipulate the UI without watching the screen by hearing the system respond to their touches.
Solution Approach 2:
The patent segments the interaction process into distinct tactile and auditory components. The mobile terminal provides segmented feedback for different menu levels and selection states, allowing users to understand the current state through tactile patterns and audio cues rather than visual information.
3Adaptability or versatility
If the navigation device provides multiple menu items and functions, then user convenience is enhanced, but the complexity of the UI screen increases
Solution Approach 1:
The patent applies segmentation by dividing the complex navigation UI into hierarchical menu levels and providing systematic audio feedback for each level. This allows the system to handle multiple functions and menu items while presenting them in an organized, manageable sequence that reduces perceived complexity for the user.
Data Source
AI summary
A method for controlling a user terminal is provided. The user terminal controlling method includes, when an external apparatus providing a UI screen is connected, providing a touch mode where a touch manipulation to navigate menu items provided on the UI screen is input, and when a predetermined touch manipulation is input in the touch mode, transmitting information corresponding to the input touch manipulation to the external apparatus.
