I’m reminded of that future-gazing video that Microsoft released a few years ago…
…which struggled to see beyond the current trend of smartphones as the user-interface.
Instead of a visionary future of new methods of interactions, the video just placed smart screens and touch-devices everywhere!
You’re right that we need to think beyond the screen, but I believe that where we are heading we will actually rely on output devices less-and-less.
Taxis will arrive when you leave the building, already knowing where you are heading. Heating will turn on as you approach your home. Door locks will open when you arrive. Lights will turn on when you enter a room.
All of these interactions are powered by the internet of things, yet the user remains passive.
