The world’s thinnest transparent screen isn’t really a screen at all, but something more like a soap bubble. An international team of researchers claims its display--which uses ultrasonic sound waves to change the properties of a soap-like film to display both flat and 3-D images--is the world’s thinnest transparent screen, and that using several of them together can even produce a holographic projection.
We caught a preview of Sony's odd, space-agey head-mounted viewer (appealingly named the HMZ-T1) back at CES in January, but we were pretty surprised to learn that not only is it not a mere demo, Sony's actually planning on, like, putting the thing in stores, where you can exchange currency for it and then take it home. Sony claims it offers an incredibly immersive 3-D experience, better than any TV. We've now played with it twice, and in some ways, that's true.
Back in 2009, we wrote about a little robotic dashboard companion called AIDA (for Affective Intelligent Driving Agent), an MIT creation that essentially read a driver's facial expressions to gauge mood and inferred route and destination preferences through social interaction with the driver.
