In-Vehicle Touch Panel Display Control for Incoming Call Isolation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The operability of in-vehicle touch panel buttons during an incoming call is compromised due to the complexity and arrangement of various operation buttons, leading to potential erroneous operations and decreased user convenience, especially for first-time or unfamiliar vehicle users.
Innovation Solution
A display control device that detects incoming calls and controls the touch panel to display answer and ignore buttons in a dedicated area, while setting other buttons in a primary area to an inoperable state, thereby preventing accidental operations and improving usability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple operation buttons for various devices are displayed on the touch panel, then the functionality and information quantity provided to the user is improved, but the operability and ease of operation deteriorates due to button arrangement complexity and potential erroneous operations
Solution Approach 1:
The touch panel display is segmented into multiple regions: a first region for displaying buttons related to the incoming call (answer button, ignore button) and a second region for displaying buttons related to other devices. This spatial segmentation allows critical call-related buttons to be isolated from other functional buttons, improving operability during incoming calls while maintaining full functionality across different display regions.
2Loss of information
If the display area for operation buttons is increased to provide more information during incoming call, then the information quantity is improved, but the risk of erroneous operation increases due to more buttons being displayed
Solution Approach 1:
The first region dedicated to incoming call buttons is provided with distinct visual characteristics (different background color, positioning) to differentiate it from the second region containing other device buttons. This local quality enhancement ensures that call-related information is prominently displayed while the distinct visual separation helps users quickly identify and operate only the relevant buttons, reducing erroneous operations.

AI summary
A display control device includes an incoming call detection unit and a display control unit that controls a display by providing a first display area and a second display area on a touch panel, and when the incoming call is detected, the display control unit displays an answer button and an ignore button of the incoming call in the second display area and sets at least one of starting buttons displayed in the first display area to an inoperable state.
