Tourism plays an important role in the economies of many countries. It is important to provide correct and relevant information to the tourist. Visitors are not always given a guided tour at the museums and other places of importance. It is infeasible to provide personal human guides to each visitor due to shortage of personnel and language constraints. Not just in tourism, providing location guidance is important in many areas like schools, colleges, companies, hospitals, exhibitions to guide people and provide them with relevant information. Audio tours using handheld devices is a solution to this problem. But traditional audio tour devices are time based, where information is displayed based on time and user has to pause and play accordingly; or they are interactive devices where users have to choose the current location to receive relevant information. This lead to development of location aware audio tour systems. But these systems rely on GPS signals for location information which is highly unreliable in indoor locations as GPS signals does not pierce through the solid walls or structures. The proposed system uses Radio Frequency Identification (RFID) which relies on radio waves. Each location or artefact is embedded with an NRF24L01 module, which is a radio frequency transceiver with limited range, that acts as a transmitter and the handheld unit given to the user also has an NRF24L01 module that acts as our receiver. Based on the signal received by the receiver unit relevant information is given via text, images and audio.
