Portable 3D Projector Sharing Stereo Content to Multiple Viewers
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current portable electronic devices, including wearable eyewear, lack effective methods for capturing and sharing visual content in a three-dimensional format that can be simultaneously viewed by multiple users, limiting immersive experiences in applications like virtual reality and gaming.
Innovation Solution
A visual content sharing system that utilizes stereo cameras integrated into eyewear devices to capture overlapping images, which are then processed and projected using a projector control device to display three-dimensional content, enabling synchronized viewing with active shutter 3D glasses.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If stereo cameras are integrated into wearable eyewear devices to capture three-dimensional visual content, then the immersive viewing experience is improved, but the device complexity and portability are worsened
Solution Approach 1:
The system divides the 3D content delivery into separate components: stereo cameras in wearable eyewear capture the content, while a separate portable projector handles the projection. This segmentation allows each device to be optimized independently, reducing overall system complexity while maintaining immersive viewing capability
Solution Approach 2:
The patent introduces a portable projector as an intermediary device that receives captured visual content from wearable eyewear and projects it for multiple viewers. This intermediary solves the complexity problem by offloading the projection function from the wearable device, allowing the eyewear to remain simple and portable while still enabling immersive 3D experiences
2Adaptability or versatility
If visual content is captured and projected for multiple users to view simultaneously, then the sharing capability is improved, but the synchronization precision between multiple viewers is worsened
Solution Approach 1:
The system employs feedback mechanisms where the portable projector receives captured visual content and projects it with timing information, allowing multiple viewers to synchronize their viewing experience. The feedback loop ensures that all users receive the same 3D content at the same time, maintaining synchronization precision across multiple devices
3Manufacturing precision
If portable electronic devices capture visual content in three-dimensional format, then the content quality is improved, but the processing and storage requirements are worsened
Solution Approach 1:
The patent extracts the heavy processing and storage requirements from the wearable eyewear device and places them in the portable projector system. The eyewear only captures the 3D content, while the projector handles the computationally intensive tasks of processing and displaying the content, reducing the data burden on the wearable device

AI summary
Systems, devices, media, and methods are presented for capturing and sharing visual content, especially three-dimensional video, with a plurality of users with compatible devices. The methods in some implementations include transmitting the visual content to a portable projector, generating a unique invite and broadcasting it to a plurality of eyewear devices, and projecting the visual content onto a screen for viewers who accepted the invite and are wearing a compatible eyewear device. For projection in 3D format, the eyewear devices include an active shutter mode. The portable projector may be housed in the interior of a case. In some configurations, the case interior is sized and shaped to support the projector and an eyewear device. The system may include multiple projectors at remote locations directed to project the visual content simultaneously.
