Friday, November 30, 2012: We all use table lamps at our study, but what if that lamp was able to transform your table into an interactive touch screen? Natan Linder, a PhD student in the Fluid Interfaces group at the MIT Media Lab has exactly done that. Linder has created an advanced light system named LuminAR that transforms any surface into interactive touch screen. LuminAR is an Augmented Reality system that projects images on any surface and can detect when anyone touches the projected image.


how much this can change today's touch screens cost?

Seems like it will be useful, but a desk lamp doesn't seem exactly mobile.

Like everything, miniturisation will happen over time. In fact, before long it will be so small it will be a choking hazard for small children and students trying to project a keyboard out of the end of their willie.

Something that projects almost parallel to a surface seems like it would be a lot better than a desklamp because when you move your fingers through the beam you would have horrible ahadows obacuring the view.
