Virtual Image Display Position Switching to Limit Driver Distraction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Virtual image display devices that switch display areas can cause annoyance and distraction to vehicle occupants, particularly when the display area is moved to a different position.
Innovation Solution
A virtual image display device that includes an actuator to switch the display area between positions, with a processor controlling the display of content based on a display rule associated with the type of content and position, minimizing distraction by adjusting the display characteristics such as size, duration, and overlap with the driver's view.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the display area is switched to a different position to provide additional information to the occupant, then the information display capability is improved, but the occupant is caused annoyance and distraction
Solution Approach 1:
The patent applies local quality by implementing different display rules for different display area positions. When the display area is at the first position (normal position), standard display rules apply. When switched to the second position (different position), specific display rules are applied that limit display characteristics such as prohibiting pop-up windows, limiting full-screen displays, or restricting certain content types. This ensures that the additional information provided at the second position does not cause annoyance or distraction to the occupant.
2Adaptability or versatility
If the virtual image is displayed in a switched position to expand display options, then the display versatility is improved, but the driver's focus on the road is disrupted
Solution Approach 1:
The patent applies parameter changes by dynamically adjusting display parameters based on the display area position. When the display area is switched to the second position, the system changes display parameters such as disabling pop-up windows, limiting full-screen content, or restricting certain content types. These parameter adjustments ensure that while display versatility is improved, the driver's focus on the road is not disrupted, as the displayed content does not cause annoyance or distraction.
3Loss of information
If the display area position is switched to provide context-aware information, then the information relevance is improved, but the display complexity increases
Solution Approach 1:
The patent applies preliminary action by pre-defining specific display rules for the second display area position. Instead of complex real-time analysis, the system has predetermined rules that are automatically applied when the display area is switched to the second position. These rules include limitations on pop-up windows, full-screen displays, and certain content types. This preliminary preparation simplifies the display control mechanism while still providing context-aware information relevant to the occupant.

AI summary
A virtual image display device is configured to display a virtual image and includes an actuator and at least one of a circuit and a processor. The actuator switches a position of a display area between a first position and a second position. The at least one of the circuit and the processor is configured to display the virtual image of a corresponding content for each of the first position and the second position according to switching of the position of the display area by the actuator. The content for the second position includes a filled background. The at least one of the circuit and the processor is configured to limit a display duration of the filled background on displaying the filled background at the second position.
