MyAngel: An Auditory Android Mobile Application for Emergency with Location-based Service

This study is aimed to propose an emergency framework with the development of an
auditory android mobile application with location-based service called MyAngel.
MyAngel app serves the functionality as a location based notification tool and
annoyance producer by the high frequency noise for attention distraction purpose by
using only a single emergency alert button. Due to the steep increment of crime rate
especially on the robberies, the outlook of the country is grim and the number of
innocent victim is also increasing. Thus, this study is addressing the problem on
difficulty in getting immediate assistance from the outsiders as well as the insufficient
self-defense techniques of the robbery victim to fight against the robbers with or without
firearms. To develop the MyAngel app, several methodologies have been conducted.
The high frequency noise and location based services (LBS) related data have been
collected through online sources and further analysis on the information gathered have
been performed through literature survey. Besides, pre-survey questionnaires were
conducted to the citizens in Selangor and Kuala Lumpur to understand their opinions on
the robbery issues. The interview session was also being carried out with one of the
robbery victim to understand the victim‟s needs during emergencies. In addition,
another interview session was done with the Operational Inspector in Selangor to
investigate if the noise criterion has been considered and proposed within the Royal
Malaysian Police (PDRM). The results indicate that all the survey respondents and
interviewed robbery victim agreed with the increase of robbery rate and they had
showed their demand on the development of MyAngel mobile application. Moreover,
the noise concept has not been adopted in PDRM yet. Thus, it will be included in
MyAngel app as one of the main functions which will be integrated with the function of
LBS to meet the requirement of the users.
