Display Terminal Magnification via Pointer Tracking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional presentation systems using a single large screen and distributed display terminals struggle with displaying detailed images, as the image on terminals is often too small and magnifying only parts of the original image, making it difficult for viewers to locate specific details.
Innovation Solution
A display system where a display terminal and a display device work together, with the terminal displaying a partial area of the device's image and a pointer mark, allowing the image to be magnified around the pointer's position, ensuring the intended part of the image is always visible and easily accessible.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the same image is displayed on the display device and the display terminals, then the display system is simple, but the displayed image on the display terminals is too small for viewers to discern detailed parts
Solution Approach 1:
The display terminal screen is divided into a magnification display area and a pointer mark display area. The magnification display area shows an enlarged view of the specific region indicated by the pointer, while the pointer mark display area shows the corresponding position on the original image. This segmentation allows viewers to see both the detailed magnified content and its location in the overall context simultaneously.
Solution Approach 2:
The pointer mark display area is nested within the magnification display area. The pointer mark shows the corresponding position on the original image, which is essentially a miniaturized version of the full display device image. This nested structure allows the terminal to display both the magnified detailed view and the context of the original image in a compact manner.
2Measurement precision
If the display terminal has a magnifying function, then detailed parts can be viewed, but just a part of the original image is displayed making it difficult to find the intended part
Solution Approach 1:
The pointer mark display area provides visual feedback by showing the corresponding position on the original image. When the magnification display area shows a detailed view, the pointer mark simultaneously indicates where this magnified region is located in the full image, giving viewers immediate feedback about the context and location of the displayed details.
Solution Approach 2:
The pointer mark acts as an intermediary element that connects the magnification display area with the original image context. It serves as a visual mediator that helps viewers understand the relationship between the magnified detailed view and its position in the overall image, eliminating the need to search for the intended part.
3Measurement precision
If the image is magnified on the display terminal, then detailed contents become visible, but the operation becomes cumbersome as users must manually locate and adjust the view
Solution Approach 1:
The system automatically performs the magnification action based on the pointer position without requiring manual intervention. When the pointer indicates a specific region on the display device image, the display terminal automatically magnifies that region and displays it in the magnification display area, eliminating the need for users to manually locate and adjust the view.
Solution Approach 2:
The display terminal automatically adjusts the magnified view to correspond with the pointer position. The system serves itself by detecting the pointer location and automatically updating both the magnification display area and the pointer mark display area, removing the burden of manual operation from the user.

AI summary
Since a display device is used in a relatively large room, it often displays images on a large screen. On the other hand, a display terminal often displays images on a small screen. Therefore, when the same image is displayed on the display device and the display terminal, the displayed image on the display terminal is so small that the viewer has difficulty in discerning details of the image, which poses a problem that the display terminal is disadvantageous. In a display system including a display terminal and a display device, the display device detects position coordinates optically pointed out by a pointer on a displayed image, and displays a given pointer mark at the detected position coordinates. The display terminal displays a magnified version of the displayed image approximately around received position coordinates serving as a center thereof, and displays a given pointer mark at the position coordinates.
