Dual-Projector Display Device with Dynamic Viewer Tracking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current display technologies lack the ability to effectively connect people by dynamically adjusting image projection based on viewer presence and interest, leading to inefficient communication and engagement.
Innovation Solution
A display device with dual projectors and a controller that switches between rear and front projection modes, using sensors to detect viewer presence and interest levels, and adjust image display accordingly, allowing for dynamic image projection on a double-sided transparent screen.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a single projector is used to project images on a screen, then the device complexity is reduced, but the ability to display images on both sides of the screen simultaneously is lost
Solution Approach 1:
The patent combines two projectors into a single integrated display system that projects images onto both sides of a screen simultaneously. The first projector projects an image on the first surface while the second projector projects an image on the second surface, merging their functions into a coordinated system controlled by a single controller that manages both projectors as a unified whole.
Solution Approach 2:
The display device achieves multi-functionality by enabling simultaneous image projection on both sides of the screen, allowing the system to serve multiple viewing purposes at once. The controller can independently manage the first and second projectors to display different images or the same image on both surfaces, providing universal adaptability for various display scenarios.
2Adaptability or versatility
If the projector continuously projects images on both sides of the screen, then the image display capability is maximized, but the energy consumption increases
Solution Approach 1:
The controller dynamically adjusts the operation of the first and second projectors based on detected viewer presence. When a viewer is detected on one side of the screen, the controller prioritizes image projection on that side while reducing or stopping projection on the opposite side. This dynamic operation allows the system to maintain full display capability when needed while minimizing energy consumption when only one side requires viewing.
Solution Approach 2:
The system employs periodic detection of viewer presence using sensors, and based on these periodic checks, the controller alternates or adjusts projection activity between the two sides. This periodic monitoring and responsive adjustment creates a rhythm of high and low energy consumption states, optimizing overall energy efficiency while maintaining adaptability.
3Adaptability or versatility
If dual projectors are used to project images on both sides of the screen, then the viewer engagement is improved, but the device complexity increases
Solution Approach 1:
The system incorporates sensors that detect viewer presence on either side of the screen and provide feedback to the controller. Based on this feedback, the controller automatically adjusts which projector is active and how images are projected. This feedback mechanism allows the complex dual-projector system to operate intelligently, managing its own complexity through automated responses to viewer conditions rather than requiring manual configuration.
Solution Approach 2:
The controller autonomously manages the operation of both projectors based on sensor input, performing self-service by automatically determining when and how to activate each projector without external intervention. The system serves itself by detecting viewer presence and independently adjusting its projection configuration, reducing the need for complex external control mechanisms.

AI summary
A display device includes a screen, first and second projectors, and a controller. The screen has first and second surfaces. The first projector projects a first horizontally non-inverted image as viewed from the first surface. The second projector projects a second horizontally non-inverted image as viewed from the second surface. The controller controls switching of an operation between the first and second projectors.
