Use-ability has been and will always be a key aspect of a valuable product because it helps us get things done. Besides Doing, there is also the need for Being, which I believe interactive products of the future will support. For the lack of a better word, I call it Pause-ability — the ability to bring people mindful Pauses.
Products we create are already present in the here and now. They are doorways that can guide us into the present moment. We can design interactions to emphasize that.
Here is a brief comparison of Usa-ability & Pause-ability: the two sides of the same product/object.
