1. ObjectiveOur objective is to build an automatic tracking application using android technology. The problem arises when people need to keep track of each others location during a trip. Manually, it is being done by calling each other or asking somebody about specific person that can waste a lot of time. So, a handy approach to automatically keep track every member in the group is required. Our focus is to develop such an android application which can help in quick tracking of each member. Our final goal is to publish this application in Android market.

2. DescriptionThe following description shows one of a scenario where this application can be used:A group of friends want to go out for hiking (or anywhere else for a trip). They all need to be in touch by keeping track of each other. One of the group members takes the role of a supervisor and rest act as members of group. They all need an android application on their physical android devices to stay in touch with each other.

3. End usersSuppose a group of school students along with their teacher go for a trip. In this case:(i) Supervisor:can be that teacher.(ii) Members: are the rest of students.

Suppose an owner of a transport business needs to keep track of all of his bus drivers:(i) Supervisor:can be that owner.(ii) Members: are all of the drivers.

4. Functional RequirementsThe basic functional requirements of our application are highlighted below:4.1. Group CreationThe supervisor can create a group and add all other members in that group including their names and cell numbers. This list of members will be stored in a single table of SQLite database.4.2. Group ValidationThe supervisors device will send requests to all group members. It will then receive response from all other group members as a confirmation.4.3. Coordinate MappingThe current coordinates of members will continuously be sent to supervisor device and vice versa. The locations will be shown by plotting coordinates on Google Maps.4.4. Defining BoundariesThe supervisor will define a distance from its location or any other location. All members are allowed to be in this specified distance only.4.5. Distance CalculationThe supervisor can find distance of each group members device from its location & vice versa.

5. Non-Functional RequirementsThe major non-functional requirements of our application are:

5.1. Time Span The total time for registering all members to the group will be less than 30secs. The time for map loading and plotting indicators on Google map will also be less than 30secs (depends upon internet connection speed). All members locations will be gathered after a time interval of 1min. 5.2. Sending NotificationsAny member will be able to send a notification to the supervisor in case of any emergency.5.3. Maintaining Activity Log A log for distances and locations of all members will continuously be maintained in SQLite Database on supervisors device. Log can also be cleared at any time. Log will be deleted if supervisors device gets inactive.6. Use case Diagram

8. Project Timeline Till Fall 2012-13 MidtermMaking group and adding members on supervisor device. Till Fall 2012-13 FinalMessage parsing during sending and receiving as well as showingGoogle maps in application. Till Spring 2013 MidtermComplete mapping of co-ordinates, distance calculation and applying limitations on distance ranges. Till Spring 2013 FinalComplete documentation and fully working and tested project The testing will be carried out regularly while developing during each phase.

9. Compatibility & Application Requirements Compatible with android devices having minimum Android OS version 2.1 (or higher). Internet access or data connection for Google Map loading.

ScopeThe supervisor and each other group member will need an android device having Track My Group android application installed and running on it. All devices are required to have internet access or data connection for running the Google maps.
