All signs point to our heading towards a future in which we will exist surrounded by software-enabled touchscreens. Why this could be a grave mistake, via Slate:
What touchscreens lack is something called affordance — an object’s built-in ability to tell you how it works. A doorknob affords turning. The button on a car stereo affords pushing. A touchscreen affords nothing. It relies on software for any affordance, which in turn relies on total immersion for the user.
What we want, apparently, is to surround ourselves with touchscreens of varying size—tiny ones in our pockets, medium-size models for our laps and dashboards, and massive versions for our walls. We want tomorrow’s vintage shops to be lined with identical, blank, anonymous slabs. We want things to be vessels for software, and nothing more. Immersion is a fantastic quality while flicking virtual birds at digital pigs in your smartphone. Immersion at 80 mph is less desirable.
