History

• According to WHO, 37 million people are blind
  throughout the world
• We would like to aid this population with the use
  of Modern Technology.

4
Old Ways

• The blind mostly rely on
• Sighted Guides
• Guide Dogs
• Drawback Dependence

5
Modern Ways

• Electronic Travel Aid (ETA)
• Drawback limited range
• GPS (Trekker by the Sendero Group)
• Drawback Outdoor use only
• Other Methods
• RFID
• Ultrasonic
• Expensive to implement

6
Our Goal

• Our goal is to help a visually impaired person
  navigate in and get acquainted to their
  surroundings as a sighted person would giving
  them independence through self reliance.

7
Assumptions

• Client cannot see but can hear
• Precision problem
• Failure to detect moving objects
• Map updated according to real situation
• Ability to use the device after short training
• Client has to move by himself

How it works GPS?
13
Routers

• A set of wireless routers are used to realize a
  positioning system, like that of GPS
  Triangulation.

14
Routers

• -Placed asymmetrically all over the building,
  covering entire floor.
• -At any location, the receiver must detect at
  least 3 routers.
• -Using router strengths, calculations can be made
  to locate user position based on MAC addresses.
• -MAC addresses map to XYZ
• coordinates of the floor-plan/map.

Database

• The Router Information table will contain the
  following columns
• macAddress is the primary key
• roomNo is the foreign key
• hardwareID is the secondary key

18
Database

• The Building Information table will look like the
  following
• roomNo is the primary key

19
Database

• The Room Information table will look like the
  following
• objectNo is the primary key

20
Database

• The Event Information table will store all the
  events that have happened
• eventNo is the primary key

21
Database

• Finally we have the user table that will store
  all the users
• userID is the primary key.
