Navigation System • A navigation system is used to guide s to a certain location.

Types of Navigation System • Automotive navigation system • Marine navigation system • GPS Based navigation system • Surgical navigation system • RFID-based navigation system

RFID-based navigation system • Proposed system is for indoor environment that utilizes only RFID system for location information retrieval. • Using Radio Frequency Identification (RFID) tags is a new way of giving location information to s. • RFID tags can be embedded almost anywhere without an energy source. • The tags stores location information and gives it to any reader that is within a proximity range which can be up to 0.1-1meters for LF & HF RFID systems. • We propose an RFID-based system for navigation in a room for blind people or visually impaired.

• The system relies on the location information on the tag, a ’s destination, and a routing server where the shortest route from the ’s current location to the destination.

• The routing system is also used to help lost s to find a new route to the same destination.

• A blind traveler can learn the route either by being guided by a sighted escort, or by verbal instructions. Once a route has been learned, successful travel requires that the individual be able to: (1) Detect and avoid obstacles and (2) Follow the route

Block diagram of proposed system

Voice recognition system • A speech analysis is done after the speaks in a microphone and inputs are thus taken. • The manipulation of the input audio signal is done at the system level. • Different operations are performed at different levels on the input signal such as Pre-emphasis, Framing, Windowing, Recognition (Matching) of the spoken word. • The speech recognition system consists of two distinguished phases. • Training session (speaker has to provide samples of their speech to train the system.) • Operation session / testing phase (speaker has to give samples of his speech to match with existing database and provides exact match) • The voice recognition module used here is Easy VR.

APR 9600 • It is low cost, high performance sound record/replay IC, incorporating flash analogue storage technique. • The IC is nonvolatile. (Recorded sound is retained even after the power supply is removed from the module.) • The device offers true single chip voice recording and play back capability for 40 to 60 seconds. • The replayed sound exhibits high quality with the low noise level. • Total sound recording time can be varied from 32 seconds to 60 seconds by changing the value of a single resistor.

ADVANTAGES & APPLICATIONS • • • •

Setting the destination is easy Less space friendly Applicable in Indoor environment like home , tourist places etc

DISADVANTAGES

• Since it is made for indoor purpose so it cannot be used in public places • Obstacle detection relies on ability

CONCLUSION • When the blind person carries this device during his journeys this gives alerts to him by voice when he reaches his destination. As this device has the selectable message options thus the can record the location name and he can directly hear the location name. It gives that how much far is his destination point up to date. It is also useful for those persons who don’t know the route for their destination points. • This is also useful for other than blind persons during journeys. Firstly integrating features of all the hardware components used have developed it. Presence of every module has been reasoned out and placed carefully thus contributing to the best working of unit. Secondly using highly advanced IC’s and with the help of growing technology the project has been successfully implemented. In this project an effort has been made to study and implement monitoring and controlling of real time industrial applications.
