American Sign Language Interpreting Gloves

For the Olin College Principles of Engineering course, a team of students wanted to create positive interaction between people who use American Sign Language (ASL) to communicate and people who don't understand ASL. The glove interprets fingerspelling and prints onto a Bluetooth-connected Android app to allow for seamless communication between two individuals. 

By using a variety of electronic materials including flex sensors, accelerometers, and an Android app conected with a Bluetooth reciever, the team created a glove that senses the motion of the hand of someone using fingerspelling and then interpret these letters into text so that other people can understand.

How To: 

You will need access to a 3D-printer to make the band that houses the electrical components. If you don’t have access to one, any material with a housing attached should work. The team also used CAD,  STL, and X3G. There is more "how to" information on the team's website

The teams used Arduino Pro Mini because it has 8 analog pins, 5 for the flex sensors and 3 for the accelerometer. 

They stitched pockets for the flex sensors on the inside of the glove, on the palm-side of the hand so that the sensors are inside of a closed fist. This makes the globe more flexible, than having the sensors on the outside, and looks better as well. The team also used small pieces of velcro to hold the tops of the flex sensors at the top of the fingers inside the gloves.
