Joshua Harlan Lifton gives his talk 'Consumer Adoption of Cross Reality Systems'.
He presented about connecting the real and the virtual world through sensor networks. The real world events are reflected the the virtual world with different types of sensors (sound, network flow, usage of electoronic power, etc.). Many of his work is based on 3D virtual space, Second Life, which is good for visualization of an event.
However, 3D virtual space is not all. Building services on the existing consumer technologies is another future extension.
