4.4. Sequence Diagram
The sequence diagram Location Detection shows the classes interactions in the detection of user’s current location. It involves the SUNDAY LBS web services call to access the location information. It is my original design for location detection. However, since my program is integrated with another student [24] for obtaining destination information, the Location Detection function is enhanced by him to provide validation checking of the received location information and re- detection of the current location.
