Design interfaces, not screens

We hear so much about mobile first. It took us few years and still we debate over methodologies how to compensate for the size of display.

Soon we’ll have trillions of connected devices in the world with the Internet of Things.

Our homes will be flooded with countless things that will be interconnected and communicate with us.

If we have problem with downscaling screen size, what will we do when we’ll have to design voice and TTS only interfaces or tactile and hectic only interfaces?
