Invisible design leads us towards the horrors of Reality Clippy. Does my refrigerator light really go off? Why was my car unlocked this morning? How did my phone go silent all of a sudden? Without highly legible systems for managing and understanding all of this ‘smartness’ we are going to get very lost and highly frustrated. The tricky business of push notifications and the Facebook privacy train wreck is just the tip of the iceberg.

The example of the Nest thermostat invisibly ‘learning’ your habits to control your home temperature is a good one. But the Nest has a highly visible interface that reassures you as to its status, tells you when it is learning, and a large dial for adjusting temperature. Beautiful, legible microinteractions. A Nest without these visual and direct manipulation interfaces would be useless, uncanny and frustrating. Nest wants UI.
