Show & TellSign Language Translator Glove Saron Paz Zvika Markfeld Tomer Daniel Oleg Imanilov
What is it? An open source software & hardware Combining: • Arduino • Sensors • Android ADK • Android
What it does? • A glove that translates a predefined vocabulary of the deaf and mute sign language into text
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
What is Lily-pad? Arduino compatible microcontroller board designed for wearablesand e-textiles
Glove sensors Flex Sensors measure finger bending WiiNunchuck= Accelerometer + Gyros Conductive tape detects fingers touching
Flex sensor • Flex Sensor changes resistance when bent • Using a voltage divider the voltage is read by Arduino ADC (10 bits)
WiinunchuckSensors Joystick Accelerometer (X,Y,Z) Gyros (Roll, Pitch) 2 Buttons I2C & Power
What is a neural network? • Interconnected group of artificial neurons • Good at pattern recognition
Software view GUI Artificial Neural Network Sensor Control Relay ADK library ADK library Serial Serial
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
