Figure 24 Data obtained in the testing of Location Detection. The testing was carried out on 10th March 06 from am to pm in Tsim Sha Tsui. Some invalid samples including the inability of location detection or the return of NULL address information are not shown in the table. 5.3. Optimality The evaluation of optimality discusses the route found according to the user’s current location and the selected destination.
Two strategies, hill-climbing search and A search have been attempted for route finding. Although A search should take a longer time in computerization than hill-climbing, there is not much different in the testing. It may due to the small size of database for coordinates while the bottleneck of the application is due to the GPRS connection. As A search strategy give a more satisfying route (Figure 25), it is used in the project.
