Indoor Positioning System [indoor location system for PDAs]

Everybody has experienced the trouble and frustration of having to find a location in an unfamiliar building. Whether it is a particular store in a shopping mall, a subject section in a library, the lecture hall for writing an exam, the meeting room of a job interview, or the hospital room of a sick relative, receptionist and directories do not provide adequate guidance to your destination. In this age of information technology, the tools are available for a better solution to this problem.Hikari Systems Corp proposes an Indoor Positioning System (IPS) for guiding users in an unfamiliar building. A handheld electronic organiser, known as a PDA, communicates with a network of beacons installed in the building to determine the location of the user and guide the user to the desired destination. We have chosen the PalmOS PDA platform due to its increasing popularity, allowing most of the PDAs currently in use to run IPS software and locate their owners without specialised hardware.
