Wearable Image Capturing Device for Accident Viewpoint Diversity
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing image collection systems for traffic accidents are limited to in-vehicle camera viewpoints, lacking diverse perspectives and only activate after an accident occurs, failing to provide suitable and timely images from the viewpoints of drivers and pedestrians.
Innovation Solution
An image capturing device worn by users, equipped with a display, communication, image capturing, positional information acquisition, and control sections, which determines a dangerous state based on user and environmental data to capture and transmit images of accident sites, along with positional and attribute information.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If images are collected only from in-vehicle cameras, then the system complexity is reduced, but the viewpoint diversity and analysis precision deteriorate
Solution Approach 1:
The system segments the image collection function across multiple independent sources: in-vehicle cameras, wearable devices, and fixed monitoring cameras. Each segment operates independently but contributes to the overall accident analysis, providing diverse viewpoints without requiring a single complex integrated system
Solution Approach 2:
The wearable image capturing device serves multiple functions: it monitors the driver's state (drowsiness, distraction), captures surrounding environment images, and provides positional information. This multi-functionality replaces the need for separate systems while enhancing analysis precision through diverse data sources
2Use of energy by moving object
If the system activates only after accident detection, then the energy consumption is reduced, but the response time for providing prevention information deteriorates
Solution Approach 1:
The wearable device continuously monitors driver state and environmental conditions before an accident occurs. By detecting dangerous states such as drowsiness or distraction in advance, the system can provide warning information and alerts before the accident happens, enabling preventive action rather than just post-accident analysis
Solution Approach 2:
The system employs periodic monitoring of driver state through sensors and intermittent image capture based on detected dangerous conditions. This periodic activation pattern reduces energy consumption compared to continuous operation while maintaining timely response to emerging hazards through regular state assessments

AI summary
An image capturing device includes: a display section attached to a head or a face of a user, and configured to display an image; a communication section configured to communicate with an external device; an image capturing section; a positional information acquisition section configured to acquire current positional information of the user; and a control section configured to capture an image of a dangerous place by the image capturing section in accordance with determination of a dangerous state, and transmit a captured image from the communication section to the external device together with the positional information acquired by the positional information acquisition section.
