Touchscreen Border Controls for Blind In-Vehicle Operation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The use of touch screens in electronic devices, particularly in vehicles, leads to increased driver distraction due to the need for visual attention during operation, which can enhance the risk of accidents.
Innovation Solution
Implementing customizable border areas on touch screens with pressure sensors and customizable control functions and prompt tones, allowing users to perform operations without direct visual attention by using touch operations on these border areas.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If touch screen control is used to reduce physical buttons, then device complexity is reduced and functions are integrated, but driver distraction increases and safety decreases
Solution Approach 1:
The border area is divided into multiple independent touch zones, each capable of triggering different control functions. This segmentation allows specific functions to be assigned to different border regions, enabling selective control without requiring full screen interaction, thus reducing distraction while maintaining functionality.
Solution Approach 2:
The border area serves as an intermediary control zone between the main display and physical buttons. It provides a middle ground that offers tactile feedback and simplified interaction compared to full touch screen control, reducing the cognitive load and visual attention required while maintaining control capability.
2Measurement precision
If full touch screen operation is required, then control precision is improved, but operation time increases and productivity decreases
Solution Approach 1:
Common control functions are assigned to border areas that can be activated with simple touch gestures requiring minimal precision. This partial action approach allows frequent operations to be performed quickly at the border while maintaining the option for more precise control on the main display when needed.
Solution Approach 2:
Frequently used control functions are pre-assigned to border areas, allowing users to access these functions immediately without navigating through menus or performing complex touch sequences. This preliminary arrangement of controls accelerates common operations while preserving full control precision on the main display.

AI summary
A device control method implementing to blindly operate an electronic device through a border, comprises determining a control function corresponding to a first border area of the electronic device in response to the first border area receiving a first touch operation, outputting a prompt tone corresponding to the control function, obtaining operation information of the first touch operation, and performing a control task of the control function based on the operation information. The electronic device and a computer storage medium are also provided.
