Space Droids Using Sign Language?, earlier post on 15 November 2011
"Background: I worked for more than a decade as a professional certified (educational) sign language interpreter. This idea occurred to me when I was looking at this picture and instantly wondered what Robonaut-2 "wanted" or why it was seemingly in the process of saying "here" or maybe "give". Imagine how fast a video of Robonaut-2 saying something in American Sign Language from space would go viral. NASA could have a competition wherein people submit questions for it to answer. NASA already has a signing astronaut and SMD and NLSI already put out books in Braille. Just a thought."
Keith's note: @AstroRobonaut just tweeted: "Did you catch that? I don't have a voice, but I sent you a message -- Hello world ... in sign language!"
