Video conferencing solved the "you talkin' to me?" problem ages ago, when business execs first started using sophisticated telepresence suites to share moisturizing tips. The thing is, catching a person's eye somehow has greater instinctive impact when you actually see them turn around to face you. That's exactly the sensation that NTT engineers have tried to replicate with the MM-Space conferencing system. It's demoed after the break by a pleasant-looking (Oil of Olay?) Japanese woman -- and even though you can't hear a word she says, the rotating, nodding translucent screen definitely lends her some extra gravitas.
