5. Evaluation After the application has been implemented, it is evaluated according to different areas which are discussed below.
5.1. Interface Design Since the application requires no users input except the main page for functions selection and all the processes are done on the server side, user interface is only required for displaying the
current location information, the informative map and the photo (Figure 23). Due to the small screen size of the PDA-phones, there are 2 views, default view and desktop view provided for users viewing webpage on the devices. According to the default view
of webpage on the PDA-phones, the oversized elements on the webpage is condensed to suit the screen display such that no horizontal scrolling is required. On the other hand, the desktop view shows the original webpage size as the desktop. The maps used in the project are of size X pixels (retrieved from centamap) which are over the size of the screen. However, the condensation of the map into a small one in default view leads to all the details on the map cannot be viewed by users. It should be viewed as desktop view in order to let users understand clearly about the route details.
Nonetheless, the display of the photo needs not be that clear or accurate which default view should be used. Concerning the audio instruction, it is embedded as background sound on webpage. Since the time taken for loading a page with
sound is long in PDA phones, it is separated into a page such that the informative map display can be with or without the audio instruction.
