Dual-View In-Vehicle Display Preventing Erroneous Passenger Touch
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In-vehicle image display apparatuses of dual-view type fail to prevent erroneous manipulations by passengers in one visual recognition direction while the driver in another direction is performing a manipulation, due to the inability to determine the origin of touch panel interactions, leading to potential misunderstandings and incorrect actions.
Innovation Solution
An image display apparatus with a display portion showing multiple images from different visual recognition directions, a manipulation reception portion, an action detection portion, and a control circuit that detects and corrects manipulations by displaying cautionary images to prevent erroneous interactions, ensuring that only the intended person can perform actions on the touch panel.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If separate icon positions are used for different visual recognition directions, then each direction can access its own icons, but persons in other directions cannot understand which icon is being manipulated, leading to erroneous manipulations
Solution Approach 1:
The system provides visual feedback by displaying the currently manipulated icon at its original position and at additional positions corresponding to other visual recognition directions. This feedback mechanism ensures that persons in any direction can identify which icon is being manipulated, preventing erroneous manipulations while maintaining easy access to icons for the active user.
2Adaptability or versatility
If touch panel does not determine manipulation origin, then any person can access icons, but causes confusion and erroneous manipulations by persons not intending to manipulate
Solution Approach 1:
The system performs preliminary action by displaying cautionary images at positions corresponding to visual recognition directions before actual manipulation occurs. When a person in one direction manipulates an icon, the system proactively displays cautionary images for persons in other directions, preventing them from accidentally manipulating the screen while maintaining their ability to access icons intentionally.
3Adaptability or versatility
If dual-view display is implemented, then both driver and passenger can see their respective images, but prevents clear identification of manipulation source across directions
Solution Approach 1:
The system adds a dimensional aspect by displaying icon positions and manipulation information across multiple spatial dimensions corresponding to different visual recognition directions. The manipulated icon is displayed not only at its original position but also at additional positions that correspond to other directions, providing spatial information about manipulation origin to persons in any direction.

AI summary
An image display apparatus includes a liquid crystal panel with a dual-view function to display two different first and second screen-sized images that are visible in a driver-seat direction and a passenger-seat direction, respectively. The first screen-sized image in the driver-seat direction contains a guidance image and a guidance manipulation image; the second screen-sized image in the passenger-seat direction contains a video image and a video manipulation image. When an occupant in the driver seat manipulates an icon within the guidance manipulation image on the liquid crystal display panel, the same guidance manipulation image is also displayed in the passenger-seat direction by replacing the video manipulation image.
