Vehicle Display Cursor Control via Peripheral Region Segmentation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Vehicle display devices often face issues with inadvertent cursor movement between screens, leading to operation errors and increased user burden, especially when screens with low correlation are displayed together, requiring a solution to limit such movement while allowing for free navigation.
Innovation Solution
A vehicle display device with circuitry that controls cursor movement between screens, restricting movement if the cursor is outside a predefined peripheral region and allowing movement if within this region, ensuring accurate operation and reducing errors.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the display device allows free cursor movement between screens, then navigation freedom is improved, but inadvertent cursor movement and operation errors increase
Solution Approach 1:
The display screen is segmented into multiple regions: a peripheral region near the boundary and a non-peripheral region in the interior. This segmentation allows different cursor movement behaviors in different areas, enabling free movement when intended while preventing inadvertent transitions.
Solution Approach 2:
Different quality characteristics are applied to different parts of the screen. The peripheral region has the property of allowing cursor transition to adjacent screens, while the non-peripheral region restricts cursor movement to the current screen. This local differentiation resolves the contradiction between free navigation and error prevention.
2Adaptability or versatility
If screens with low correlation are displayed together, then information diversity is improved, but operability difference and operation errors increase
Solution Approach 1:
By segmenting the screen into peripheral and non-peripheral regions, the system maintains consistent operability rules across different screen types. The peripheral region always allows transition, providing a predictable interaction pattern regardless of screen content diversity.
3Speed
If the cursor can move freely across the entire screen, then operation speed is improved, but operation errors increase
Solution Approach 1:
The screen is given different quality characteristics in different regions. The peripheral region permits rapid cursor transition to adjacent screens for efficient navigation, while the non-peripheral region restricts movement to prevent errors. This local quality differentiation maintains speed where safe and accuracy where needed.

AI summary
A vehicle display device includes a display configured to show a first screen and a second screen and circuitry configured to control a position of a cursor on the first screen, on the second screen, and between the first and second screens. The circuitry moves the cursor from the first screen to the second screen if the cursor is located in a peripheral region when the user performs an operation to move the cursor from the first screen to the second screen. The circuitry restricts movement of the cursor from the first screen to the second screen if the cursor is located outside the peripheral region when the user performs an operation to move the cursor from the first screen to the second screen.
