In contrast with conventional cassette audio tape exhibition tours, the presented museum guide system is implemented on palm-based personal digital assistants (PDAs), so as to provide a multimedia touring experience for visitors. and then automatically retrieves the related multimedia information of the exhibit that the visitor is gazing at. As the visitor walks up to another exhibit, without any clicks or operations, the screen on the PDA will be changed to the related multimedia information of that exhibit automatically. Basically, the developed museum guide system plays the role of a personal guide assistant, so as to construct the mobile learning environment in museums.
Block Diagram:
The system will consist of ARM-7 32 bit processor. It consists of inbuilt DAC inside it. The audio files will be stored in flash memory in “WAV” format. The processor will read these files and play them back using audio amplifier circuit. The information will be also stored in memory, which will be displayed on LCD at particular exhibit. The RFID reader will be used to detect particular exhibit. Passive RFID tags will be placed at every exhibit.
Optional:
Moreover, the museum guide system is capable of being aware of the current position of the visitor, by using GPS receiver.
