Display System Mirroring Screen Region for Accessibility
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Large-sized electronic whiteboards are difficult to operate, especially for users with short stature, as they require extensive movement, making it challenging to access and interact with the screen effectively.
Innovation Solution
A display system with a controller that captures and displays a part image of a frame in one region on a different region, allowing operations on one region to be mirrored on the other, enabling convenient access and interaction by allowing users to operate one region to affect the other, even if it's outside their arm's reach.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If the electronic whiteboard is made large-sized to provide sufficient display area, then the display area is increased, but the ease of operation deteriorates for users with short stature
Solution Approach 1:
The patent creates a virtual copy of the display content by projecting an image of the display screen onto a secondary surface (such as a table or wall). This allows users to interact with the displayed content from a closer distance and at a more convenient height, effectively copying the visual information to an accessible location without changing the physical display board itself.
2Shape
If the display board height is increased to provide better viewing angles, then the viewing angle is improved, but the accessibility for short users deteriorates
Solution Approach 1:
The patent introduces an intermediary device (such as a camera or image sensor) that captures the display content and transfers it to a projection system. This intermediary allows the content from the high-mounted display to be reproduced at a lower, more accessible position, mediating between the fixed display location and the user's reach.

AI summary
A display system includes a display module and a controller. The display module is configured to display a first frame including a part image, wherein the part image is located in a first region of the first frame. The controller is configured on the display module and is configured to capture the part image of the first frame and displays the part image in a second region different from the first region. The controller responds to an operation for one of the first region and the second region, the same operation for the other of the first region and the second region is performed.
