gloves
A pair of gloves that reads sign language and speaks it. Flex sensors measure how far each finger bends, a gyroscope carries the hand's angle and acceleration, a Kalman filter cleans the signal, and Bluetooth pairs both gloves to an app that prints and says the meaning. Intended as a substitute voice, not a demo.
Four questions,
four answers
A flex sensor along each finger changes resistance as it curls. Read the change, get a bend level per finger.
An MPU-6050 gyroscope records the hand's angle and acceleration, so a gesture is a path, not a pose.
Bluetooth 4.2 — the only option that pairs both gloves to one device at the same time. WiFi and NFC were tried and dropped.
An Arduino Nano packs both streams into one format and a Kalman filter smooths them before anything is matched.
Teachable,
out loud
The app shows the meaning on screen and speaks it, so a hearing person needs no training to be part of the conversation. New signs are added by recording the live glove data against a word — the vocabulary grows by use rather than by a firmware release.
Out in the world
Carrying a project is half the work. I captained the team through eight international competitions, presented at exhibitions and technology conferences, and handled ten media interviews about the gloves.
