Wireless Video Training System with Head-Mounted Display
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional training systems lack instant visual feedback, making it difficult for individuals to observe and modify their physical expressions and movements in real-time, which hampers effective training in disciplines that require precise movement and form.
Innovation Solution
A video training system that uses a camera and a head-mounted display with a wireless video link to provide a real-time, mirrored self-image, along with a video processing system that selects the optimal camera perspective and incorporates features like Chroma-Key color replacement for multiple camera perspectives and remote instructor involvement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If conventional training systems are used, then training can be conducted without complex equipment, but instant visual feedback is unavailable making it difficult to observe and modify physical expressions
Solution Approach 1:
The system implements real-time video feedback by capturing the subject's movements via camera and displaying them on a head-mounted display, enabling immediate observation and adjustment of physical expressions and movements during training
Solution Approach 2:
A wireless video transmission system acts as an intermediary between the camera and head-mounted display, transmitting video signals without physical cables to provide feedback while maintaining subject mobility and reducing system complexity
2Productivity
If a camera and head-mounted display system is implemented, then real-time visual feedback is provided, but the system complexity and equipment requirements increase
Solution Approach 1:
The head-mounted display allows subjects to independently observe and evaluate their own movements in real-time without requiring constant instructor intervention, enabling self-directed training and improving training effectiveness
Solution Approach 2:
The system replaces oral feedback from instructors with electronic video feedback through wireless transmission and head-mounted display, providing more precise and immediate feedback while reducing the need for complex mechanical training apparatus
3Ease of operation
If oral feedback from instructor is used, then simple equipment is required, but instant visual observation of behavior is difficult preventing real-time modification
Solution Approach 1:
The system adds a visual dimension to feedback by displaying video images on the head-mounted display, allowing subjects to observe their movements from multiple angles and perspectives that are not available through oral feedback alone
Data Source
AI summary
A self-viewing environment and an apparatus enabling unrestricted movement of a subject within the self-viewing environment are disclosed. A subject wears a head mounted display that receives a video signal by wireless transmission. The subject is positioned within the field of view of a video camera that sources a video image for transmission to the subject. Video mirror-imaging and signal-processing are employed to adapt the perceived self-viewing environment for the benefit of the subject.
