Swiping and tapping on flat screens is something we’ve learned to deal with in smartphones, tablets and other touchscreen gizmos, but it doesn’t come close to the ease of typing on a hardware keyboard or playing a game with a physical controller. To that end, researchers Craig Shultz and Chris Harrison with the Future Interfaces Group (FIG) at Carnegie Mellon University have created a display that can protrude screen areas in different configurations. It’s a concept we’ve seen before, but this version is thinner, lighter and more versatile.FIG’s “Flat Panel Haptics” tech can be stacked under an OLED panel to create the protrusions: imagine screen sections that can be inflated and deflated with fluid on demand. This could add a new tactile dimension for things like pop-up media controls, keyboards and virtual gamepads you can find without fumbling around on the screen.
