There are a wide variety of mobile phone emergency response applications exist for
both indoor and outdoor environments. However, outdoor applications mostly provide
accident and navigation information to users, and indoor applications are limited
to the unavailability of GPS positioning and WiFi access problems. This work describes
the proposed mobile augmented reality application (MARA) that allows indoor users
to retrieve and manage information for emergency response and navigation that is spatially
registered with the real world. The proposed MARA utilizes feature extraction for
location sensing in indoor environments as during emergencies GPS and WiFi systems
might not work. The MARA delivers critical evacuation information to smartphone users
in the indoor environment and navigation information in the outdoor environments.
MARA is designed specifically for acquiring spatial analysis, situational awareness,
and visual communication. The MARA uses existing permanent features such as room numbers
and signage in the building as markers to display the floor plan of the building and
show navigational directions to the exit. Through the visualization of integrated
geographic information systems and real-time data analysis, our mobile AR application
provides the current location of the person, the number of exits, and user-specific
personalized evacuation routes. The Mobile AR application provides information to
support effective decision-making during emergencies for both building occupants and
emergency responders.
Decision Making System
During emergencies, accurate and timely dissemination of information plays a critical
role in saving lives and minimizing damage. As technology continues to advance, there
is an increasing need to explore innovative approaches that enhance situational awareness
and facilitate efficient decision-making in emergency scenarios.
