For designers, one of the most important things to understand is that design is only one step in the product development process.
Ideally, you’d be able to point at different objects around your home and tell them what to do—turn lights off and on, preheat your oven, mute the TV. This is a classic vision of the Internet of Things, where most of the time there are no screens involved at all. It’s hard to imagine this vision becoming a commercial product without some sort of combinations of hand gestures and voice input. After all, we don’t always want to be surrounded by screens that help us do simple things—we’d like things to respond directly.
Often, it's the smallest details that matters the most.
