Portable Device for Disaster Information Visualization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional devices for displaying disaster and safety information lack portability and mobility, requiring a workstation or desktop, and are difficult to use due to limited intuitive view changes and repeated user input.
Innovation Solution
A portable device equipped with a GPS module, information receiving module, sensor module, processor module, and display module that receives position information, detects inclination, and visualizes disaster and safety information in first or third person views, allowing for easy viewing and navigation without repeated user input.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a workstation or desktop is used for visualizing disaster and safety information, then the visualization capability is improved, but the portability and mobility deteriorate
Solution Approach 1:
The patent combines the disaster information visualization system with a portable mobile device (smartphone or tablet), merging previously separate functions of desktop visualization software with mobile computing capabilities. This integration enables high-quality 3D terrain and disaster information visualization while maintaining portability and mobility for field use during emergencies.
2Productivity
If conventional devices are used for disaster information display, then the information processing capability is improved, but the ease of operation deteriorates due to non-intuitive view changes requiring repeated user input
Solution Approach 1:
The system automatically detects the user's viewing direction using the device's sensor module (accelerometer/gyroscope) and adjusts the observation view accordingly without requiring manual input. The device serves itself by autonomously changing the viewpoint based on physical orientation, making the operation intuitive and eliminating the need for repeated user commands to switch between first-person and third-person views.

AI summary
A portable device is configured to display disaster and safety information and a method is configured to control the portable device to display the disaster and safety information. The portable device includes a global positioning system (GPS) module for receiving position information of the portable device and an information receiving module for receiving the disaster and safety information. A sensor module of the portable device detects an inclination of the portable device and the processor module of the portable device visualizes the disaster and safety information in a first person view or a third person view according to the sensed inclination. A display module of the portable device displays the disaster and safety information based on weather prediction information and/or forest fire damage prediction information.
