Robotic Hand Teaches Sign Language and 'Rocks on'
From: Gadget New - 07/13/2009

The Sign Language Emulating Robotic Assistant teaches the deaf to speak and
rock 

Here's a robotic hand that teaches sign language, including the international
sign for "rock on." J.D. Ritchey and his fellow mechanical engineering
colleagues (Tim Campbell, Nick Haub, and Brian Taylor) from Colorado State
University created an acrylic hand to assist in teaching sign language. The
Sign Language Emulating Robotic Assistant features all the digits of a human
hand. Punch in a specific letter and the hand forms the sign language
position. The students take sign language a bit further than standard
letters. Punch in "rock on" and the hand forms the rock concert sign with the
index finger and the pinky showing the classic fan symbol for keep on rocking.
