  3. Our Project 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.

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

  6. How Does It Work? Traverse the aisle

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

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

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

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

  11. How Does It Work? Detecting objects to avoid.

  13. System Description

  14. Navigation System Necessary Components of a Navigation System:

  15. Navigation System Voice Communication • Using Microsoft SAPI • Text To Speech • Speech Recognition • Programming Language: C# • Speaker Independent • Custom Lexicon

  16. What is RFID? Radio Frequency IDentification

  17. RFID System Alien Higgs “Squiggle” RFID Tag 3.9” M10 RFID Reader and Directional Antenna 0.5”

  18. Collision Avoidance

  19. Collision Avoidance

  20. Collision Avoidance

  21. Collision Avoidance

  22. Collision Avoidance

  23. Collision Avoidance

  24. Collision Avoidance

  25. Hall Effect Sensor Usage

  26. Microcontroller Function 1 Microcontroller Hall-Effect Sensor M10 RFID Reader Server Radio Unit 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.

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

  28. Backend Server Software • Calculates the best route for the shopper • Contains all RFID tag information in database • Scalable for different grocery store layouts • 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

  29. Testing and Verification • Accuracy of RFID reader at various distances • Range testing of wire replacement module • Accuracy of navigation system • Range testing for collision avoidance • Overall product testing after integration

  30. RFID/Communication Board Circuit Boards Partitions • PIC18F26J11 Microcontroller • M10 RFID Reader • PB6-915 Directional Antenna • Wire Replacement Radio • Hall Effect Sensors Sensor/Feedback Board • PIC16F616 Microcontroller • Ultrasonic Sensors • Dualshock2 Motors

  31. Development Cost

  32. Production Cost

  33. Our Engineering Team • Navigation System: • David Shullo • Tatsani Inkhamfong • RFID System: • Vinty Siev • Alain Iamburg • Collision Avoidance System: • Andres Flores • Kevin Eichholz • Hardware: • Joseph O’Neill
