The eButton’s reporting extends even further than food and exercise: It can determine the amount of time wearers spend watching TV or sitting in front of a computer screen and how much time they spend outdoors. It tracks where food is bought, how meals are prepared, which restaurants are visited, and what items are ordered.

Retrieving the results of eButton is convenient [...] it’s as easy as transferring pictures from a digital camera onto a computer. To protect participants’ privacy, the data are coded so they cannot be read until scanned by a computer to block human faces.

In other words, there will be no need to find that pen you keep misplacing — or even to dig your smartphone out of your pocket to record a note.

The system employs a depth-sensing camera, similar to the Microsoft Kinect, to track the user’s fingers on everyday surfaces.

This allows users to control interactive applications by tapping or dragging their fingers, much as they would with touchscreens found on smartphones or tablet computers.
The projector can superimpose keyboards, keypads and other controls onto any surface, automatically adjusting for the surface’s shape and orientation to minimize distortion of the projected images.

“First thing I should probably say here is that I built this without even thinking what its function would be. I just thought it would be cool to add a cam to the front of my Eye-Trek goggles. As it turned out these where ideal for use with augmented reality applications.  I am also working on putting them to use for other software. Such as gps overlays and night vision (like being the terminator, but more scrawny).” [...] “Other idea is to have it on all day and log on to chat roulette, give them that “being john malcovich” feeling.”

The idea is that the dog is trained to trek around disaster areas, and when they find a stranded straggler, they’ll sit in front of them. When he’s walking around, his jacket will play sounds to make nearby survivors aware of their doggy internet saviour. A hammy sounding American guy will then tell you, from the vest, that this dog is a messenger dog, and guide the rescued through recording a voice or picture message

The device created by Massachusetts Institute of Technology (MIT) scientists can turn any surface into a touch-screen for computing, controlled by simple hand gestures. The gadget can even take photographs if a user frames a scene with his or her hands, or project a watch face with the proper time on a wrist if the user makes a circle there with a finger.

The MIT wizards cobbled a Web camera, a battery-powered projector and a mobile telephone into a gizmo that can be worn like jewelry. Signals from the camera and projector are relayed to smart phones with Internet connections.

“Other than letting some of you live out your fantasy of looking as cool as Tom Cruise in ‘Minority Report’ it can really let you connect as a sixth sense device with whatever is in front of you,” said MIT researcher Patty Maes.

Maes used a Technology, Entertainment, Design Conference stage in Southern California on Wednesday to unveil the futuristic gadget made from store-bought components costing about 300 dollars (US).
