A blog about our Embedded Systems final project. We are building an American Sign Language decoder, essentially a glove that can sense ASL letters and print them on a screen.

Andddd We're Done!
With the final tweaks mentioned in previous posts, we were able to decode 24 of the 26 letters of the alphabet to some satisfactory degree of accuracy. Of course, some letters decode more robustly than others, and the letters O and V remain to be implemented. O is very similar to C and E in configuration, and V is very similar to R and U. With a couple more sensors, it would have been possible to decode these last two letters as well (and perhaps make some of the others more robust). However, we had maxed out the number of GPIO pins on the Firefly. With a change of platform, or additional pins, we would be able to decode the full alphabet.
The final product was demonstrated at the ESE350 Demo Day as well as an additional demo day for professors and other students. We had a great time showing our work and were glad that the final product was a success!
