QR Code Based Indoor Navigation with Voice Response

Smart phone based navigation applications are very useful in the day-to-day life. Efficient and user friendly navigation can be provided to the user by many applications available in market. Using GPS unit of the Smart phone these navigation applications provide accurate navigation for outdoor locations. But providing an accurate navigation inside a closed building is still a challenge. It has become very difficult for the day-to-day visitors to remember the interior map of each of the places accurately with the rising number of buildings. Indoor guidance is becoming a significant issue with the increasing number of buildings. It is hence more convenient and appropriate if the visitors could simply view the interior map of the building on their mobile phone, wherever and whenever it is needed. The system describes an Android based indoor map guidance system that assists and guides visitors inside buildings. Indoor navigation with the help of QR codes is a cost effective smart phone solution to provide location information to the user optically. QR codes will be used all across the building to carry the information required for the navigation system. The user need to scan the nearest QR code inside the building. Then he can download the map of the indoor location. The navigation application decodes the geo location details from QR code and points the location in the Map. The user can find the current location and navigate to a targeted destination. The mobile application will use the QR codes to provide accurate indoor navigation for the user. The indoor navigation system uses QR codes for two purposes: to provide the user link to the map of the indoor location and to provide the current location details to the user. The system also provides a voice response module which allows blind people to determine their current position inside the building. In the implementation phase, the Android SDK is used to develop the client interface and the Apache Tomcat server is used for the web server. For the web based client interface JSP is used as the front end and MySQL is used as the database server.
