Adaptive Display Screen Positioning for 3D Viewing Regions
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
3D displays, including spatial reality displays, often break the illusion of depth and parallax when the viewer moves outside a limited 'sweet spot' or predetermined viewing region, restricting the viewer's mobility and creating a confined viewing experience.
Innovation Solution
An apparatus with an adjustment mechanism, such as a turntable capable of rotating and translating about multiple axes, is used to dynamically adjust the display screen's position and orientation based on location-tracking data, ensuring the viewer remains within the predetermined viewing region, thereby maintaining the 3D illusion and enhancing the viewing experience.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the viewer moves outside the predetermined viewing region, then the viewer's mobility is improved, but the 3D illusion breaks and the viewing quality deteriorates
Solution Approach 1:
The display screen is made dynamically adjustable through rotation circuitry and translation circuitry that can reposition the screen in real-time. The system continuously monitors viewer position and automatically adjusts the display screen's orientation and location to maintain optimal viewing conditions, transforming a static display system into a dynamic one that adapts to viewer movement.
Solution Approach 2:
The system employs location-tracking devices to continuously monitor the viewer's position and provides feedback to the control system. Based on this feedback, the system determines whether the viewer is within the predetermined viewing region and automatically adjusts the display screen accordingly, creating a closed-loop control system that maintains 3D illusion quality while permitting viewer movement.
2Adaptability or versatility
If the display screen position is fixed, then the device complexity is reduced, but the viewing area is limited and viewer experience deteriorates
Solution Approach 1:
The adjustment mechanism serves multiple functions: it rotates the display screen about a first axis to adjust viewing angle, translates the display screen along a second axis to adjust viewing distance, and can operate autonomously based on location-tracking feedback. This multi-functional mechanism expands the viewing area while consolidating adjustment capabilities into a single integrated system.
Solution Approach 2:
The system incorporates autonomous operation capability where the adjustment mechanism automatically adjusts the display screen position and orientation based on viewer location data without requiring manual intervention. The system self-regulates to maintain optimal viewing conditions, reducing the need for complex manual control interfaces while expanding adaptability.

AI summary
An apparatus for holding a display screen, the apparatus includes reception circuitry to receive, from at least one location-tracking device, location information indicative of a location of a viewer; position-tracking circuitry responsive to the location information to determine a relative position of the viewer relative to the display screen, viewing-region-checking circuitry to determine whether the relative position of the viewer is within a predetermined viewing region, and adjustment control circuitry responsive to the viewing-region-checking circuitry determining that the relative position of the viewer is outside of the predetermined viewing region to control adjustment circuitry to adjust the position and/or orientation of the display screen to place the relative position of the viewer in the predetermined viewing region.
