Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display technologies fail to effectively reflect the motion of a user in a three-dimensional space onto a user image displayed on a screen, limiting the level of immersion and engagement in 3DCG applications.
Innovation Solution
A display apparatus and method that includes an image acquisition unit, image extraction unit, registration unit, display control unit, coordinate generation unit, and motion detection unit to acquire, process, and display user-drawn images in a three-dimensional space, allowing the motion of objects to be detected and reflected in the user image's operation on the screen.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional display technologies are used to show user images in 3DCG screens, then the display can be maintained with standard functionality, but the motion of the user's body cannot be reflected in the user image operation
Solution Approach 1:
The system divides the display functionality into separate modules: a motion detection unit that captures body movements, a coordinate generation unit that converts movements to screen coordinates, and a display control unit that renders the user image. This segmentation allows motion reflection capability to be added without completely redesigning the display system.
Solution Approach 2:
The patent introduces coordinate information as an intermediary element that bridges the physical motion detection and the digital display rendering. The coordinate generation unit creates intermediate coordinate data from detected motion, which then guides the positioning and operation of the user image on the screen, enabling motion reflection without direct coupling between detection and display systems.
2Adaptability or versatility
If motion detection and coordinate generation systems are added to reflect user body motion in user images, then the level of amusement and immersion is improved, but the device complexity increases
Solution Approach 1:
The display control unit is designed to perform multiple functions: it not only controls the standard display rendering but also integrates motion detection results, generates coordinate transformations, and adjusts user image operations based on detected movements. This multi-functionality reduces the need for separate dedicated components for each function.
Solution Approach 2:
The system transitions from traditional two-dimensional screen coordinates to three-dimensional spatial coordinates by incorporating depth information from motion detection. The coordinate generation unit maps three-dimensional body movements into three-dimensional display space, adding a spatial dimension to user interaction that enhances immersion without requiring completely new display hardware.

AI summary
A display apparatus includes an image acquisition unit, an image extraction unit, a registration unit, a display control unit, a coordinate generation unit, and a motion detection unit. The coordinate generation unit generates, based on a detection result of a detection unit configured to detect the position of an object in a three-dimensional space, coordinates of the object in a screen. The motion detection unit detects a motion of the object based the coordinates in the screen generated by the coordinate generation unit. The display control unit displays a first image on the screen. When the motion is detected by the motion detection unit, the display control unit further displays a second image on the screen based on coordinates corresponding to the detected motion, and changes the display of the first image.
