Gestures and Unicode Input

[Ben Burdette]

I don't want to discourage you guys, I'm all for developing a motion
recognition system.  It would be cool for using with a speakerphone
output to spell words when you don't want to look at the screen.  Using
gestures to navigate an audio based UI would be great for the blind too.

But for password entry it seems very insecure.  I mean, wouldn't
entering a password with gestures be like sending secret messages with
signal flags? Anyone who knows the system could just read what you were
entering.
