Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a stereoscopic image is displayed without specialized glasses, then the viewer can recognize the stereoscopic image, but the viewer cannot achieve a feeling of directly operating on the stereoscopic image
Solution Approach 1:
The patent uses an operating body (such as a pen or pointer) as an intermediary between the viewer and the virtual stereoscopic image. The operating body is tracked in three-dimensional space and used to interact with the stereoscopic image, allowing the viewer to perform operations like pointing, selecting, and manipulating virtual objects without wearing specialized glasses, thereby achieving a direct operation feeling while maintaining reliable stereoscopic image recognition
Solution Approach 2:
The patent replaces the mechanical system of specialized glasses with an optical display system that directly presents stereoscopic images to both eyes. Instead of using polarized or shutter-based mechanical mechanisms in glasses, the system uses a display screen with specific optical properties to create the stereoscopic effect, eliminating the need for wearable optical components while enabling direct hand interaction with the virtual image space
2Reliability
If specialized glasses are used to display stereoscopic images, then the viewer can recognize the stereoscopic image, but the viewer cannot directly operate on the stereoscopic image
Solution Approach 1:
The patent extracts the stereoscopic display function from the specialized glasses and transfers it to the display screen itself. By removing the glasses from the system, the viewer's hands and operating bodies are no longer blocked by optical components, enabling direct interaction with the virtual stereoscopic image while the display screen maintains the stereoscopic effect through its optical design
Solution Approach 2:
The patent introduces an operating body as a mediator that bridges the gap between the physical hand and the virtual stereoscopic image. The operating body is tracked in three-dimensional space and used to interact with the virtual objects, allowing the viewer to perform operations like pointing and selecting without the interference of specialized glasses, thereby achieving both reliable stereoscopic recognition and direct operation capability
3Ease of operation
If the operating body is tracked in three-dimensional space, then the viewer can directly operate on the stereoscopic image, but the device complexity increases
Solution Approach 1:
The patent replaces complex mechanical tracking systems with optical and computational methods. Instead of using mechanical sensors and actuators to track the operating body, the system uses image processing and coordinate transformation algorithms to calculate the three-dimensional position of the operating body based on two-dimensional image coordinates, significantly reducing mechanical complexity while maintaining accurate tracking
Solution Approach 2:
The patent creates a virtual copy of the operating body's position and orientation in the three-dimensional virtual space. By calculating corresponding three-dimensional coordinates from two-dimensional image coordinates and maintaining the spatial relationship between the operating body and virtual objects, the system enables direct operation without requiring complex physical tracking mechanisms

AI summary
An image display device of an embodiment includes an image display means for displaying a parallax image on a display screen, a first coordinate calculating means for calculating virtual spatial coordinates of a stereoscopic image recognized by a viewer of the parallax image, a second coordinate calculating means for calculating spatial coordinates of an operating body to be operated by the viewer, and an event generating means. The event generating means generates a certain event accompanying a change of at least one of the parallax image or an image on the display screen other than the parallax image when a distance between the spatial coordinates of at least one point of the stereoscopic image calculated by the first coordinate calculating means and the spatial coordinates of at least one point of the operating body calculated by the second coordinate calculating means is equal to or less than a certain threshold.
