Augmented Reality Screen System Using Physical Markers
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing augmented reality systems require multiple physical screens to achieve a wider display range, which is costly and inconvenient due to weight, volume, and space limitations, and lacks portability.
Innovation Solution
An augmented reality screen system that uses a head-mounted display device to scan physical marks, determining their position and rotation information, and projects a virtual extended screen based on these markers, allowing for adjustable virtual screens that can replace physical ones and create new usage scenarios.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If multiple physical screens are used to expand display range, then the display area is increased, but the cost, weight, volume, and space requirements increase
Solution Approach 1:
The patent uses virtual copies of screens projected through augmented reality to replace physical screens. The AR device projects virtual display surfaces that can be positioned anywhere in the user's field of view, eliminating the need for multiple physical monitors while maintaining expanded display functionality.
Solution Approach 2:
The patent replaces the mechanical physical screen system with an optical/electronic AR projection system. Instead of physically placing multiple screens, the system uses cameras, processors, and display optics to generate and position virtual screens in three-dimensional space.
2Area of stationary object
If multiple physical screens are used to expand display range, then the display area is increased, but the device complexity and setup difficulty increase
Solution Approach 1:
The AR device serves multiple functions: it acts as a camera to capture physical markers, a processor to calculate marker positions and orientations, and a projector to generate virtual screens. This multi-functional approach consolidates what would otherwise require multiple separate physical devices into a single wearable unit.
Solution Approach 2:
The system automatically detects physical markers in the environment, calculates their spatial relationships, and generates appropriately positioned and oriented virtual screens without requiring manual configuration. The AR device self-adjusts to the user's viewing angle and automatically adapts the virtual screen placement.
3Reliability
If physical screens are used, then stable display is achieved, but portability and flexibility are reduced due to fixed screen size and location
Solution Approach 1:
The virtual screens in the AR system are dynamic and can be repositioned, resized, and reoriented in real-time based on user needs and environmental conditions. The screens are not fixed in position or size like physical monitors, allowing flexible adaptation to different usage scenarios while maintaining stable visual output through the AR optics.

AI summary
An augmented reality screen system includes an augmented reality device and a host. The augmented reality device is configured to take a physical mark through a camera. The host is configured to receive the physical mark, determine position information and rotation information of the physical mark, and fetch a virtual image from a storage device through a processor of the host. The processor transmits an adjusted virtual image to the augmented reality device according to the position information and the rotation information, and the augmentation device projects the adjusted virtual image to a display of the augmented reality device. The adjusted virtual image becomes a virtual extended screen, and the virtual extended screen and the physical mark are simultaneously displayed on the display of the augmented reality device.
