Vehicle Touch Display Scroll Control for Icon-Tile Parallax
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display control technologies fail to effectively emphasize the parallax effect of icons displayed in front of tiles on a screen, leading to insufficient rendering of this visual cue.
Innovation Solution
A display control device that detects user scrolling triggers to increase the relative position between tiles and icons with acceleration and decrease it with deceleration, enhancing the parallax effect and visual distinction between tiles and icons.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If the scroll display is controlled to move at a slower speed when an item matching search condition is displayed, then the user can observe the displayed item more carefully, but the parallax effect rendering between icons and tiles becomes insufficient
Solution Approach 1:
The patent applies dynamics by making the relative position between icons and tiles change dynamically during scrolling. The controller increases the relative position at a prescribed acceleration when scrolling starts, and decreases it at a prescribed deceleration when scrolling stops. This dynamic adjustment creates a parallax effect that enhances visual distinction between icons and tiles during the scrolling operation, resolving the contradiction between scroll speed and parallax effect rendering.
2Quantity of substance
If icons are displayed overlapping tiles on a screen, then information density is improved, but visual distinction between front-layer icons and background tiles becomes insufficient
Solution Approach 1:
The patent applies dimensionality change by introducing a relative position dimension between icons and tiles. Instead of only displaying icons overlapping tiles in a static two-dimensional layout, the system dynamically adjusts the relative position in the horizontal direction during scrolling. This creates a perception of depth and layering, allowing users to distinguish between front-layer icons and background tiles while maintaining high information density.
3Manufacturing precision
If the relative position between tiles and icons is increased during scrolling, then the parallax effect is enhanced, but the complexity of the display control system increases
Solution Approach 1:
The patent applies parameter changes by dynamically adjusting the relative position parameter between icons and tiles during scrolling operations. The controller increases the relative position at a prescribed acceleration when scrolling starts, and decreases it at a prescribed deceleration when scrolling stops. This parameter adjustment is implemented through software control, which manages the complexity while achieving enhanced parallax effect rendering.

AI summary
A display control device includes a display and a controller. The display is configured to be installed in a vehicle and capable of touch operation. The controller configured to control an image displayed on the display. The controller detects a start trigger indicating that a user has started scrolling to the left or right on the display, and increases a relative position between a tile and an icon at a prescribed acceleration with a passage of time from detection of the start trigger. The controller detects a stop trigger indicating that the user has stopped scrolling, and reduces the relative position between the tile and the icon at a prescribed deceleration with a passage of time from detection of the detected stop trigger.
