3 There are 15 million blind and visually impaired people in the U.S., according to Research to Prevent Blindness. The National Science Foundation is funding the exploration of technologies that can benefit disabled persons. One major problem for visually impaired people is finding their way around unfamiliar places. Our team has developed a method to assist the visually impaired in navigating and locating products in a grocery store setting. Our Project

4 Problems Facing the Visually Impaired: Independently Locating Products Avoiding Obstacles Our Solutions: Shopping Cart Navigation System Collision Warning System Navigation in a Grocery Store

6 How Does It Work? Traverse the aisle

7 Press the Push-to-Talk button How Does It Work?

8 Shopper inputs a voice command into the headset How Does It Work?

9 Shopper inputs a voice command into the headset How Does It Work?

10 Route is generated by the backend server How Does It Work?

11 Detecting objects to avoid.

25 Hall Effect Sensor Usage

26 Microcontroller Function 1 Hall-Effect sensor causes the MCU to issue a “read” command to the M10. The RFID tag info is sent to the server via the Xbee radio. Hall-Effect Sensor Microcontroller M10 RFID Reader Server Radio Unit

27 Microcontroller Function 2 To set a destination, the user presses the push-to-talk button then speaks into the headset. Microcontroller Server Radio UnitPTT Button Headset

28 Backend Server Software Calculates the best route for the shopper Contains all RFID tag information in database Provides a Graphical User Interface (GUI) to inform the manager/cashier of any problems  A computer monitor can be placed at the clerks counter to alert them if the shopper needs help  Scalable for different grocery store layouts
