future of computer

I already know a interesting computer!! I saw it on TV! Surprisingly, the computer didn\'t have the key boad. How can I type letters on computer? That's what I wanted to say. The comuter has skelton keyboard, rather it better to say that the computer doesn't have a keyboad physicall, but actually, there are key borad. The key bord is made by laser beam. I can use the laser beam in anywhere such as on the desk. I think it's difficult to explain it by words, so I'll introduce its details. See this site!!
As my expectation, I really hope computer will be able to use without losing eyesight. Seriouslly, I really hope they can make it!
In addition,omputer will be able to send things,,except e-mail... like Kuronekoyamato.. Then, we can sent anything usung computer!!
I always think computer would be able to send smell...when I see some picture of cake and seet...I want to sniff these smell!!!!!!!!!!!!!
