Display Device Attribute Setting via Sample Image Selection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display devices that allow pen or finger input on a screen for drawing require separate designation frames for each attribute setting, leading to increased operation load as the number of attributes increases, making user interaction cumbersome.
Innovation Solution
A display device with a detection unit and control unit that displays two images with different attribute settings based on user input, allowing the user to set both attributes with a single operation by selecting from a sample image group, reducing the number of operations required.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If separate designation frames are displayed for each attribute setting, then each attribute can be set individually, but the number of operations increases and user operation load increases
Solution Approach 1:
The patent combines multiple attribute settings (color, thickness, line type) into a single integrated sample image selection operation. Instead of requiring separate designation frames for each attribute, the system displays sample images that represent combinations of multiple attributes, allowing users to set all attributes simultaneously by selecting one sample image, thereby reducing the number of operations and time required
Solution Approach 2:
The patent uses sample images as visual copies or representations of the actual attribute settings. Each sample image serves as a template that pre-defines multiple attribute values, allowing users to quickly apply complex attribute combinations without manually configuring each attribute separately, thus improving operation efficiency
2Adaptability or versatility
If multiple designation frames are displayed for different attributes, then comprehensive attribute settings are available, but the interface complexity and device complexity increase
Solution Approach 1:
The patent merges multiple attribute designation functions into a single sample image selection interface. Instead of displaying separate designation frames for color, thickness, line type, and other attributes, the system presents integrated sample images that embody multiple attribute settings simultaneously, maintaining versatility while reducing interface complexity
Solution Approach 2:
The sample image selection mechanism serves multiple functions simultaneously: it displays visual previews, represents multiple attribute settings, enables selection, and applies settings all in one interface element. This multi-functional approach replaces multiple specialized designation frames, reducing overall interface complexity while maintaining comprehensive attribute setting capabilities

AI summary
A display device includes: a display unit displaying an image on a display surface; a detection unit detecting a position on the display surface pointed by a pointing unit; and a control unit causing the display unit to display an image based on the position detected by the detection unit. The control unit causes the display unit to display a first image and a second image having a different setting of a first attribute and a second attribute from the first image. The control unit decides a setting of the first attribute and the second attribute used for the image based on the position detected by the detection unit, according to an operation on the first image or the second image.
