Apart from being a mobile solution (instead of the Microsoft Surface that is attached to a table), what I found very interesting in this TED Talk was the fact that this solution accommodates the use of physical paper in our daily lives in very different contexts of daily life and also the border less notion of work and non-work situations in individuals life, thus addressing support for information space transitions.
I'm listing this future technology as something that will change present PIM needs if, like it is said, the costs can be reduced with mass fabrication. Somethings where not said and need to be better understood namely, system requirements that allow the system to recognize so many different actors. I imagine that there is a need for individuals to «feed» some of this information in the background, like the information that allows to «recognize» the actors that we cross with (considering that not all the people we meet are public figures ;)
More details on the Sixth Sense Project in a short paper describing the prototype, Mistry, P., Maes, P., and Chang, L. (2009). WUW - wear Ur world: a wearable gestural interface. In Proceedings of the 27th international Conference Extended Abstracts on Human Factors in Computing Systems (Boston, MA, USA, April 04 - 09, 2009). CHI EA '09. ACM, New York, NY, pp. 4111-4116:
"Information is traditionally confined to paper or digitally to a screen. In this paper, we introduce WUW, a wearable gestural interface, which attempts to bring information out into the tangible world. By using a tiny projector and a camera mounted on a hat or coupled in a pendant like wearable device, WUW sees what the user sees and visually augments surfaces or physical objects the user is interacting with. WUW projects information onto surfaces, walls, and physical objects around us, and lets the user interact with the projected information through natural hand gestures, arm movements or interaction with the object itself."
