Forehead Headgear with Dual Cameras for 3D Video Capture
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current technologies for image and audio data transmission, such as online services like Skype and Facetime, limit the ability to present realistic three-dimensional representations of events due to the use of two-dimensional video streams and restrict the wearer's range of action, lacking interaction capabilities and comprehensive communication management.
Innovation Solution
A headgear device with two cameras arranged horizontally on the forehead, stabilized at three points on the head, allowing for three-dimensional image data capture and transmission without restricting the wearer's movement, combined with a system for interactive communication that includes a server for connection management and real-time data processing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If two-dimensional video streams are used for image transmission, then bandwidth requirements are reduced and compatibility is improved, but realistic three-dimensional representation of events cannot be achieved
Solution Approach 1:
The patent transitions from two-dimensional video transmission to three-dimensional image data transmission by positioning cameras at specific spatial coordinates (x, y, z) to capture depth information. This dimensional enhancement allows realistic 3D representation while managing bandwidth through selective data transmission and compression techniques.
2Reliability
If the transmitter's range of action is restricted to achieve stable image capture, then image quality is improved, but the sender's freedom of movement is limited
Solution Approach 1:
The headgear is stabilized at three distinct points on the head (forehead, temples, or cheeks), segmenting the stabilization function across multiple anchor points. This distribution of stabilization points provides mechanical redundancy that maintains image stability while allowing the wearer natural head and body movements.
Solution Approach 2:
The stabilization system adapts dynamically to the wearer's movements rather than restricting them. The three-point stabilization mechanism flexes and adjusts with head motion, maintaining consistent image capture geometry while preserving the sender's freedom of movement and natural behavior.
3Loss of information
If three-dimensional image data is transmitted in near real-time with interaction capabilities, then communication realism is improved, but system complexity and infrastructure requirements increase
Solution Approach 1:
A central server acts as an intermediary between multiple transmitters and receivers, managing the complex tasks of receiving three-dimensional image data, performing transcoding and compression, routing data streams, and coordinating interaction capabilities. This centralized mediation handles system complexity while maintaining simple client devices.
4Stability of the object's composition
If the headgear is stabilized at multiple points on the head, then wearing stability is improved, but the device structure becomes more complex
Solution Approach 1:
The headgear divides the stabilization function into three separate attachment points distributed across the head (forehead, temples, or cheeks). This segmentation provides mechanical stability through triangular geometry while keeping each individual attachment point simple and modular, avoiding a single complex stabilization mechanism.
