The Kinected Conference by MIT Media Lab uses all kinds of tricks to help improve people's focus and discussions through video conferencing. For instance, if you are faced with a few people around a table on the screen, the Kinect can pick up which person is talking and blur the other faces out, keeping focus on the speaker (demonstrated above). It also times how long someone has been speaking (useful for timed presentations), freeze frame if you want to do something else but make it look like you are listening, and use augmented reality for making projects.

It's done by using C++ software and openFrameworks library, plus two networked locations with video screens, the Kinect, calibrated microphones, and a lot of algorithms (see the map plan). Check out the video below and convince yourself that you don't wish you could use this at work.

third video down: Helicopter Taxi, is awesome. At first I thought the idea of a "digital toy" that's so close to a physical one—but just on an iPhone screen—was whack. But after watching the video my mind is spinning the storytelling possibilities of simple augmented reality.

Spot-on production values in this video by @Coudal for Field Notes: (filed under: good design can sell *anything*)

Like the telephone game for drawing.

Salman Khan talks about how and why he created the remarkable Khan Academy, a carefully structured series of educational videos offering complete curricula in math and, now, other subjects. He shows the power of interactive exercises, and calls for teachers to consider flipping the traditional classroom script -- give students video lectures to watch at home, and do "homework" in the classroom with the teacher available to help.
