In-Vehicle Display Control to Block Misread Touch Input While Driving
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display devices in vehicles may lead drivers to incorrectly perceive that they have accepted an operation while driving, due to warning images not being clearly recognized as such in peripheral vision.
Innovation Solution
A display device with a detection unit and display control unit that prevents information changes and attention calling notifications when an operation is detected while the vehicle is driving, ensuring the driver does not mistakenly recognize the device as accepting input during driving.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If warning information is displayed to alert drivers of operations during driving, then driver awareness is improved, but the driver may still fail to recognize it as a warning and mistakenly believe the operation was accepted
Solution Approach 1:
The patent applies color changes by displaying warning information in red when an operation is detected during driving. This color change creates a strong visual contrast that immediately captures the driver's attention and clearly communicates the warning nature of the message, preventing misinterpretation as a normal operation confirmation.
Solution Approach 2:
The patent implements preliminary action by displaying the warning information before the system actually executes or confirms the operation. This advance warning gives the driver time to react and prevents the operation from being processed while the vehicle is moving, eliminating the risk of erroneous operation acceptance.
2Ease of operation
If the display device accepts operations while driving, then ease of operation is improved, but safety deteriorates due to potential driver distraction and erroneous operation acceptance
Solution Approach 1:
The patent applies preliminary anti-action by proactively preventing operations from being accepted during driving through the warning display mechanism. The system detects the driving state and blocks operation acceptance before it can occur, counteracting the potential harmful effect of driver distraction and erroneous operation acceptance.
3Reliability
If the display device provides continuous operation feedback, then operational reliability is improved, but driver distraction increases while driving
Solution Approach 1:
The patent implements dynamics by making the display behavior adaptive to the vehicle's operating state. The system dynamically adjusts its feedback mechanism based on whether the vehicle is detected to be driving or stationary, providing operation feedback only when it is safe to do so, thereby eliminating unnecessary driver distraction while maintaining operational reliability.

AI summary
An embodiment provides a display device including a display unit, a storage unit, a detection unit configured to detect an operation on the display device, and a display control unit configured to cause the display unit to display information, the display control unit being configured to not change information displayed by the display unit to information corresponding to the operation detected by the detection unit and to not cause the display unit to display attention calling information indicating attention calling regarding the operation when the detection unit detects the operation while the vehicle is driving.
