Smart SignHand

Here is my idea: an anthropomorphic hand made with LEGO technics, mindstorms and a magic brick who can hear and understand vocal commands, resting on a base that also reproduces the mobility of the wrist.

The system is able to understand the sounds and when I pronounce a letter the hand translates it into sign language.

It could be a fun model to build and to code. Also a mode to learn sign language in a fun way, especially for people who can hear, to reduce the distance with deaf people.

In many countries the sign language has some differences, so american sign language (ASL) is a bit different from italian sign language (LIS) but thanks to coding possibilities of mindstorms it is not a problem to code the right position to the hand.

You could program different games:

GAME 1. the hand "says" a letter and it is necessary to guess it, if you give the correct answer the system recognizes it and the hand gives a positive feedback, otherwise a sign of error.

GAME 2. I pronounce a letter and the hand shows me how it translates into language of signs.

GAME 3. the hand "says" a whole word (one letter at a time) and I have to guess it. Again the brick that listens is able to determine whether I have guessed it or not, and the hand gives the feedback.

it could be a way to make people more sensitive to disability, fun to build for children or students in the range 11-15 years old, useful to learn coding and useful for society. ;-)

PS: in the image, an example of how GAME 1 might work.
