Remote Operator Video Replay for Vehicle Support Handover
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Operators in remote vehicle support systems cannot continuously check the surrounding situation of a vehicle due to the dynamic nature of the environment, leading to potential delays or inappropriate support.
Innovation Solution
A system that displays past vehicle footage in a shortened duration and switches to real-time footage upon completion, allowing continuous monitoring of the vehicle's surroundings.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If the operator monitors the vehicle surroundings in real-time only after assignment, then the system complexity is reduced, but the operator cannot check the surrounding situation from the past leading to delayed or inappropriate support
Solution Approach 1:
The system performs preliminary recording of surrounding situation videos before the operator is assigned. When remote support is requested, the system retrieves and displays the pre-recorded video from the time of request, allowing the operator to immediately see the situation as it was when support was needed, eliminating the delay of waiting for real-time camera activation.
2Loss of information
If the system displays the entire past video from request time to current time, then complete information is provided, but the display time becomes excessively long reducing productivity
Solution Approach 1:
The system extracts and displays only the critical portion of the past video - specifically the segment from the time of remote support request to a predetermined duration before the current time. This extraction approach provides the operator with the most relevant information (the situation when support was requested) while excluding unnecessary earlier footage, thus maintaining information quality while reducing display time and improving operational efficiency.
3Ease of operation
If the system continuously displays real-time video only, then the device complexity is minimized, but the operator cannot understand how the situation evolved leading to inappropriate support decisions
Solution Approach 1:
The system prepares and stores video recordings at different time points (real-time video at assignment moment, and historical videos from request time). When support is needed, it sequentially presents these pre-prepared video segments to the operator, enabling them to understand the evolution of the situation from the request moment through to the present, thereby improving decision-making accuracy.
Data Source
AI summary
A remote support system includes one or more processors configured to display a video acquired from a camera mounted on a vehicle or an infrastructure camera on a display device of a remote operator terminal. When a past video needs to be displayed on the display device, the remote support system shortens a first past video recorded from a past first timing to a current time to a second period shorter than a first period from the past first timing to the current time and displays the second period on the display device. After the display of the first past video corresponding to the second period is finished, the remote support system switches the display of the display device to a real-time video.
