This demo, from the Fluid Interfaces Lab of Pattie Maes at MIT, and spearheaded by PhD student Pranav Mistry, was the buzz of TED. SixthSense [pranavmistry.com] is a wearable device with a projector that paves the way for profound interaction with our environment. The innovative device allows to literally overlay everyday objects with real-time visualizations, in order to inform users about normally invisible information relevant to the objects in view. Imagine ingredient pie charts beamed on top of apple pies. Imagine Facebook comments projected on people's foreheads.
