A successful lab project designed to provide experience of working with the Wireless Application Protocol (WAP) is described. The resulting prototype, WAPcam, demonstrates how an interactive camera can be controlled remotely via mobile phones. The establishment of functionality requirements for WAPcam leads to an identification of the various new technologies--HTML, CGI, Perl, PHP, Java, servlets, applets, XML, and so on--that were needed for the building of the prototype. Cost considerations dictated that the development phase would be on a WAP simulator. The need to reduce a 640x480 pixel jpeg image provided by the interactive camera to a 100x70 pixel black and white display while maintaining acceptable image quality provided a special challenge, as did the concurrency problem, which was inherent in a decision to allow multiple users to access the camera concurrently. The authors also report on the special efforts taken to keep a high level of motivation among the students, efforts that minimized the problems introduced by flaws in the current WAP implementations and the limitations in the standard. The paper concludes with a report of responses to the prototype and a discussion of applications in which its use would be appropriate.
