  1. Show & TellSign Language Translator Glove Saron Paz Zvika Markfeld Tomer Daniel Oleg Imanilov

  2. What is it? An open source software & hardware Combining: • Arduino • Sensors • Android ADK • Android

  3. What it does? • A glove that translates a predefined vocabulary of the deaf and mute sign language into text

  4. How does it work? Lily-Pad Arduino samples sensors attached to glove ADK board relays data from the Lily-Pad to Android Android uses a back propagation Neural Network to analyze data

  5. What is Lily-pad? Arduino compatible microcontroller board designed for wearablesand e-textiles

  6. Glove sensors Flex Sensors measure finger bending WiiNunchuck= Accelerometer + Gyros Conductive tape detects fingers touching

  7. Flex sensor • Flex Sensor changes resistance when bent • Using a voltage divider the voltage is read by Arduino ADC (10 bits)

  8. Wiinunchuck

  9. WiinunchuckSensors Joystick Accelerometer (X,Y,Z) Gyros (Roll, Pitch) 2 Buttons I2C & Power

  10. What is Android ADK?

  11. What is a neural network? • Interconnected group of artificial neurons • Good at pattern recognition

  12. Software view GUI Artificial Neural Network Sensor Control Relay ADK library ADK library Serial Serial

  13. How we built it?

  14. Prototyping Flex sensors

  15. Prototyping Flex sensors

  16. Flex sensor output

  17. Adding nunchucksensors

  18. The problem with ASL

  19. The final glove

  20. Challenges • How to position flex sensors? Fix tip to top and pass through sewn loops • How to distinguish between R,U,V,S,E,T,N? Conductive tape detects fingers touching • How to distinguish between each letter? Time based • How to record movement? Freeze in the middle

  21. Demo

  22. Who are we?
