This paper describes the implementation of a wireless sensor network for a multimedia guidebook scenario incorporating a pointer-sensor system for the selection of locality-aware information. An Information Point Station Network (IPSN) was developed and consists of several Information Point Stations (IPSs) placed at locations of significance, with access to information items on a centralized server. In the multimedia guidebook scenario, a user selects a particular information item to view, either by way of a menu system appearing on their mobile computing device (MCD) or a more intuitive pointer-sensor system as described in this paper. Laser sensors are placed next to prominent or relevant objects, and can be either directly connected to an IPS, or function as isolated sensor nodes. The pointer is attached to the MCD by way of a serial port and the user points the pointer at the laser sensor next to the object for which they require information. The information is then sent to the MCD via Bluetooth. The implementation was found to be successful and was tested with multiple users accessing information items from a given IPS as well as multiple IPSs attached to the centralized server. Still, there is further work to be done on the isolated sensor nodes.
