This concept video shows how 2-D and 3-D graphics could be combined in a real-time map display: As you tilt the phone, it shifts from a 2-D map to a 3-D rendering of the real world, with labels superimposed over the images of the buildings in front of you. Select your destination by tapping on it, tilt the phone back to horizontal, and a 2-D map reappears, with directions to the spot you want to go.

TAT's concept video for an enhanced 3-D display makes it look as if the icons and dialog boxes on your smartphone are "floating" above the display. As you tilt the phone back and forth, the shadows move appropriately, emphasizing the sense of depth. (To everyone else, it just looks like you're wiggling your phone back and forth while staring at it with a curious intensity.)

TAT's "Glassy" user interface is a demonstration of how even midrange feature phones can have snazzy, Apple-like user interfaces. In this video, someone with a generic Nokia phone gets a spiffy Cover Flow-like album browser.

The "Juggle" user interface from TAT is a way of making it easy for users to switch from app to app, via a sort of floating desktop. Once you're inside an app, you can bring up a curved list of other apps by swiping your finger along the edge of the screen.

TAT's concept for "augmented identity" would use face recognition to identify people, then superimpose links to their social networking profiles so you can find out more about them. Usefully, the concept would let you select which of your social networks appear at any given time, so you could highlight your YouTube channel when you're out partying, but replace it with your LinkedIn profile when you're giving a presentation at work.

Most of TAT's design work involves custom user interfaces and widgets for phone manufacturers. But the company recently released three live wallpaper schemes for Android devices: Artemia, an undersea landscape; Blue Range, an isometric landscape with cartoon bears and foxes (shown here); and Retro Pixels, a wallpaper reminiscent of an old videogame. All three are free and are available in the Android Market.
