Display Control Device Gesture Feedback via Layered Transparency
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display control systems for devices with music playback functions, especially those with visualizer functions, face challenges in providing high visibility feedback for gesture operations, often requiring adjustments such as reducing brightness or changing button layouts.
Innovation Solution
A display control device that includes a display control unit displaying decoration images distinct from operational images, detecting user touch operations, and processing units that create feedback images by moving or transforming these decoration images to indicate gesture operations, thereby providing high visibility feedback without altering the visualizer's brightness or layout.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the visualizer function displays images during music playback, then the aesthetic appeal and user experience are improved, but the visibility of feedback for gesture operations deteriorates
Solution Approach 1:
The display screen is segmented into multiple layers: the visualizer layer displaying aesthetic images during music playback, and the feedback layer displaying gesture operation feedback. These layers are superimposed with different transparency levels, allowing both the visualizer content and feedback information to be simultaneously visible without interfering with each other.
Solution Approach 2:
The patent introduces a new dimension of display by using layered superimposition with varying transparency. Instead of choosing between displaying visualizer images or feedback (single dimension), the system uses multiple transparent layers stacked together, creating a multi-dimensional display structure where both elements coexist and are simultaneously perceivable.
2Difficulty of detecting and measuring
If the brightness of the visualizer is reduced to improve feedback visibility, then the visibility of feedback is improved, but the overall visual quality and aesthetic appeal deteriorate
Solution Approach 1:
The display is segmented into separate transparent layers: the visualizer layer maintains its original brightness and visual quality, while the feedback layer is displayed with higher transparency to ensure visibility. This segmentation allows each layer to maintain its optimal display characteristics without compromising the other.
Solution Approach 2:
Different regions of the display have different transparency characteristics. The visualizer layer maintains high brightness and low transparency to preserve aesthetic appeal, while the feedback layer uses high transparency to ensure visibility. Each layer is optimized locally for its specific function rather than uniformly adjusting the entire display.
3Difficulty of detecting and measuring
If button layouts are changed to improve feedback visibility, then the visibility of feedback is improved, but the device complexity and operation difficulty increase
Solution Approach 1:
The user interface is segmented into distinct functional layers: the visualizer layer for aesthetic display and the feedback layer for operation confirmation. This segmentation eliminates the need to reconfigure button layouts or operational structures, as feedback is provided through the transparent overlay layer without altering the underlying interface design.
Solution Approach 2:
Instead of changing the layout of operational elements (buttons, controls) to improve feedback visibility, the patent inverts the approach by placing feedback information on top of the existing layout through a transparent overlay. This maintains the original intuitive operation layout while adding visible feedback confirmation.

AI summary
A display control device including a display control unit that displays a decoration image on a display unit, the decoration image being different from images used for operation, a detection unit that detects a user's touch operation made on the display unit, and a processing unit that executes a process associated with the touch operation involving a predetermined trajectory. When the touch operation involving the predetermined trajectory is detected while the decoration image is displayed, the display control unit displays a feedback image that is made up of the decoration image and indicates that the touch operation involving the predetermined trajectory has been detected.
