AR Presentation Device with Dynamic Depth Tracking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current augmented reality presentation devices in medical environments face challenges with limited transmission bandwidth, reduced image quality, and miscoordination during interventional procedures due to inadequate registration of virtual and real data, and issues with stereoscopic viewing that lead to unrealistic depth perception and data identification among multiple monitors.
Innovation Solution
A presentation device with a recording unit, a first display unit, and a processing unit that captures the relative positioning of display units and generates augmented reality by virtual mapping, allowing for content-based adjustment of graphical presentations to ensure precise overlay and alignment of virtual and real data, even when displayed simultaneously across multiple monitors.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If image data is supplied to multiple augmented reality presentation devices simultaneously through a supply unit, then multiple viewers can access the data, but the transmission bandwidth is limited and image quality is reduced
Solution Approach 1:
The patent divides the image data processing into separate pathways: a first pathway supplies visible image data to multiple second display units for simultaneous viewing, while a second pathway supplies hidden graphical information (including depth data) to recording units for later retrieval. This segmentation allows multiple viewers to access data without competing for the same bandwidth, maintaining image quality in both pathways.
Solution Approach 2:
The patent introduces a hidden graphical information layer as an intermediary that carries depth and positional data separately from the visible image data. This intermediary pathway allows the system to convey additional spatial information without increasing the bandwidth requirements of the main visible data stream, thereby maintaining image quality while enabling multi-viewer accessibility.
2Adaptability or versatility
If stereoscopic filter glasses are used with a 3D monitor to enable multiple viewers to see three-dimensional image data, then depth perception is provided, but the individual stereoscopic images cannot be adjusted to current viewing points resulting in unrealistic depth perception
Solution Approach 1:
The patent makes the depth information dynamic by continuously tracking the positions of multiple viewers and adjusting the hidden graphical information accordingly. The recording units capture depth data that is updated in real-time based on viewer locations, allowing the system to adapt to changing viewing points and maintain accurate depth perception throughout the presentation area.
Solution Approach 2:
The system implements feedback by using recording units to continuously monitor viewer positions and adjust the hidden graphical information to match current viewing points. This closed-loop approach ensures that depth perception remains accurate even as viewers move, correcting the static limitation of traditional stereoscopic filter glasses.
3Adaptability or versatility
If multiple monitors display different image data without communicative coupling, then data can be displayed across multiple devices, but it is not possible to identify the data displayed by the monitors
Solution Approach 1:
The patent merges the visible image data with hidden graphical information that contains identification and contextual data. By combining these data types into a unified system where monitors and recording units communicate through the common platform, the system maintains multi-monitor display capability while preventing information loss through the integrated identification layer.

AI summary
A presentation device for displaying a graphical presentation of an augmented reality is disclosed. The presentation device includes a recording unit, a first display unit, and a processing unit. The recording unit is configured to capture a relative positioning of the first display unit in respect of a presentation area and capture a second set of graphical information. The processing unit is configured to generate an augmented reality based on a received dataset, supply a graphical presentation of the augmented reality by virtual mapping to the presentation area, and adjust the augmented reality and/or the graphical presentation thereof as a function of the second set of graphical information. The first display unit is at least partially transparent and is configured to display the graphical presentation of the augmented reality.
