Auto-Delay Video Playback for Seamless Action Review
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional mirror alternatives, such as camera-screen combinations, fail to provide a reliable and natural image of oneself, especially in scenarios like trying on clothing or video conferencing, as they differ significantly from a traditional mirror reflection.
Innovation Solution
A computerized technique that enables real-time video processing to display both live and delayed video streams on a monitor, allowing users to see themselves from all angles without interrupting the flow of activities like training sessions, using a processor, camera, and memory to store and retrieve video frames for delayed playback.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a standard mirror is used, then the user can see real-time reflection, but the user cannot see how the clothing looks from the back or all angles
Solution Approach 1:
The patent uses a camera to capture the user's image and displays it on a screen, creating a visual copy that can be manipulated to show different angles including the back view, while maintaining the authenticity of the user's actual appearance
Solution Approach 2:
The system transitions from a 2D mirror reflection to a multi-dimensional viewing experience by capturing images from multiple angles and displaying them sequentially, allowing users to see themselves from front, back, and side views
2Loss of information
If a video recorder is used for training review, then the user can view the recorded action, but the user must interrupt the training flow to record and review
Solution Approach 1:
The system continuously records video in the background during training activities, so that when the user wants to review, the footage is already captured and ready for immediate playback without interrupting the training flow
Solution Approach 2:
The recording function operates continuously throughout the training session, maintaining the useful action of capturing training data without breaking the continuity of the user's training activity
3Loss of information
If delayed video mode is activated, then the user can review past actions, but the real-time feedback is interrupted
Solution Approach 1:
The system dynamically switches between real-time video feed and delayed replay modes based on user interaction, allowing seamless transition between immediate feedback and review of past actions

AI summary
A computer implemented method for automatic presentation of delayed video. During normal operation real-time video feed is sent to a digital screen for presentation and is also sent to memory for storage. When a delay trigger is issued, the system either freezes the frame presented in that instance or stores a time indicator. The system then monitors delay time and, when the delay time is reached, the system starts fetching frames from the memory, starting either from the frame immediately following the frozen frame or from the frame that was stored at the time indicator, and sends these frames to the digital screen for presentation. The system then monitors delay period and, when the delay period arrive, the system reverts to normal mode wherein real-time video feed is sent to a digital screen for presentation and is also sent to memory for storage.
