In three major steps, evaluation describes the entire operation of the application:
- The first and most important step is to fill out the contact information in the application that has been created. Those contacts could include our relatives, friends, and the police. When the app is first installed on the smart phone, the above contact information should be provided. The information you provide will be saved by the application.
- The second major step is to send GPS information (in the form of Co-ordinates or a URL that leads to the person's location, such as Google) to the registered contacts during dangerous situations or when the person needs to be rescued. This step is only performed when the application's rescue button is pressed. This step can only be completed when the device is connected to a proper mobile network and the device's location service is turned on (GPS).
- The work done in sending the message containing the location URL to the registered contacts is the third major step. An SMS is sent to the registered contacts with the location of the person. As a result, the application can track the person's exact location in real time, which is the primary goal of the proposed system, and the person can be rescued.
