Vehicle Display Icons for Touch and Non-Touch Switch Recognition
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Vehicle occupants may mistakenly identify switch types due to indistinguishable visual cues for touch and non-touch switches in existing display systems, leading to unease and potential incorrect operations while driving.
Innovation Solution
A display control device that displays icons for both touch-sensor-type and non-touch-sensor-type switches on a front dashboard display, with dynamic visibility adjustments based on switch operations, emphasizing visual cues for touch switches and reducing visual information for non-touch switches to enhance tactile perception.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If icons for both touch and non-touch switches are displayed with the same visual appearance, then the display is simple and clear, but the vehicle occupant cannot distinguish between different switch types, leading to mistaken identification
Solution Approach 1:
The patent applies different visual qualities to icons representing different switch types. Touch switch icons display with visual indicators (such as highlighted borders or specific colors) to distinguish them from non-touch switch icons. This local differentiation allows the vehicle occupant to identify switch types through visual cues while maintaining a unified icon design system.
2Loss of information
If visual information is provided for all switches, then the vehicle occupant can easily identify switch locations, but the tactile sensation of non-touch switches becomes less noticeable
Solution Approach 1:
The patent dynamically adjusts the display state of icons based on the operational context. When a non-touch switch is being operated, its corresponding icon is set to a non-displayed state or reduced visibility state, allowing the vehicle occupant to focus on tactile feedback. When not in use, the icon is displayed to provide location information. This dynamic adjustment balances visual guidance with tactile perception.
3Loss of information
If the display shows information for multiple switches simultaneously, then comprehensive information is available, but the vehicle occupant may feel unease due to information overload
Solution Approach 1:
The patent extracts and prioritizes information display based on the currently active switch. When a specific switch is being operated, only the icon corresponding to that switch remains visible, while other icons are set to non-displayed states. This extraction of relevant information reduces cognitive load and eliminates the unease associated with information overload, while still providing complete operational feedback for the active switch.
Data Source
AI summary
A display control device for a vehicle includes a memory, and at least one processor connected to the memory. The processor displays, on a display portion provided at a front side of a driver's seat, plural icons corresponding to a steering switch group that has a touch-sensor-type first switch and a non-touch-sensor-type second switch. The plural icons include a first icon corresponding to the first switch and a second icon corresponding to the second switch. In a case in which a touch operation of the first switch is sensed, the processor displays both the first icon and the second icon, and, in a case in which a non-touch operation of the second switch is sensed, the processor sets both the first icon and the second icon in non-displayed states.
