I have thought of this considerably as a deaf writer that needs a better communication system. (I talk just don't hear.) However I was thinking more along the lines of speech recognition as a tool for pocket sized help. (you talk I read)seems more considerate of everyones needs. I never thought of the keypad idea, however I would probably use one if it became available and was portable.Roundtuit (talk) 15:17, 11 January 2008 (UTC)
I would have to wonder just how difficult it is to touch-type with this. IMHO that's rather important. --220.127.116.11 19:23, 15 October 2007 (UTC)

I don't think the projected image is actually a hologram. Projected holograms, AFAIK, are a very recent invention (last couple of years), and even then there's a bit of a trick to it. I'm thinking of the horribly expensive ones used famously in the stage shows of some singer or other.
Isn't the beamed image just a simple flat projection? The correct word would be something like "image" or "projection" over "hologram". Tho I haven't seen one of these in person so I can't say conclusively.
