AR Collaboration System Using Radiation Emitters for Pose Tracking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current augmented reality collaboration systems fail to deliver sufficient visual quality, field of view, and user experience due to low image quality, lack of close-up views, incompatibility with users wearing eyeglasses, and complex input and control features, leading to a steep learning curve and incompatibility with existing collaboration systems.
Innovation Solution
The development of augmented reality collaboration systems featuring physical and virtual 'holopads' that use radiation emitters and sensors to determine user device poses, allowing for intuitive interaction with virtual content projected in a predetermined location, enabling geographically distributed users to collaborate as if around a shared table, with features like 3D videoconferencing and user-friendly input methods.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If traditional augmented reality systems are used, then users can view virtual content, but the visual quality and field of view are insufficient
Solution Approach 1:
The patent transitions from 2D display screens to 3D volumetric holographic displays, enabling virtual content to be projected in three-dimensional space. This dimensional change provides both high visual quality through realistic 3D rendering and expanded field of view by distributing content across multiple spatial dimensions, resolving the contradiction between image quality and viewing area.
Solution Approach 2:
The system divides the display into multiple radiation emitters arranged in patterns, creating segmented projection zones. Each emitter contributes to the overall holographic image, allowing the system to maintain high visual quality in each segment while collectively providing an expansive field of view through the combined emission zones.
2Adaptability or versatility
If conventional AR headsets are designed, then virtual content can be displayed, but users wearing eyeglasses cannot use them
Solution Approach 1:
Instead of requiring users to wear AR headsets that interact directly with their eyes, the system creates optical copies or projections of virtual content in physical space. Users can view these holographic projections with their naked eyes or through eyeglasses without any special optical requirements, making the system universally accessible to all users regardless of whether they wear corrective lenses.
3Ease of operation
If intuitive interaction methods are implemented, then user experience improves, but the system becomes incompatible with existing collaboration systems
Solution Approach 1:
The system implements multiple interaction modalities simultaneously - gesture recognition, voice commands, and traditional input devices can all be used with the holographic display. This multi-functional approach provides intuitive interaction through natural gestures and voice while maintaining compatibility with existing collaboration systems that rely on conventional input methods, allowing seamless integration across different platforms and user preferences.
