Researchers show off 'flex' interface for touchscreens No, it's not an actual flexible touchscreen, but this so-called "flex" interface developed by some researchers at Osaka University is still pretty novel. Rather than simply moving content off the screen when you're browsing something like Google Maps, it treats what's on the screen as an elastic, flexible material and squishes the content as it gets closer to the edge of the screen, which still lets you see it while you focus on a different area. That, the researchers say, would be just as effective on phones and other devices in addition to large touchscreens, and it would obviously be fairly easy to implement. Check it out in action in the video above.
