Many people around the world suffer from speech problems, and can't communicate with others in the same way we do it. To solve that problem, I, Bruno Moraes, and my research partner, Pedro Jorge, developed a Sign Language Translation Glove. Acctually, it only works with Brazillian Sign Language.
The Glove is also able to control a LEGO Wheelchair wirelessly with the movement of your fingers.
We're both 15, we don't know that much about electronics and programming, so go easy.
For this project, we made use of flexible potentiometers (available at sparkfun) to measure each finger's position. This potentiometer, together with a 10K resistor form a Voltage Divider, that feeds de Arduino ADC. We used an Arduino Mega 2560, but UNO or similars is ok.
Bill of Materials:
1 - Glove ( We used a Nike Dry Fit Tour Golf )
1 - Arduino Mega 2560 (http://www.sparkfun.com/products/9949)
1 Arduino UNO ( Optional, used for the wheelchair side control)
5 - Flexible potentiometers (http://www.sparkfun.com/products/8606)
5 - 10K Resistors
2 - 2.2K Resistors (Optional, used for the wheelchair side control)
2 - 2N2222 Transistors (Optional, used for the wheelchair side control)
1 - Breadboard
2 - XBee Series 1 Modules
2 - XBee Explorer Regulated
1 - Soldering Iron
1 - Solder
1 - Stranded wire
Step 1: Attach the Sensors
After, solder 15cm stranded wire pieces to each of the sensor leads.
Remember to reinforce de pin-end of the sensor, this area is susceptible to kinking and eventual failure. Electrical tape ou heatshrink is fine.
