Good design is invisible—meaning the user doesn’t notice the design while they are using it. Users only need to focus on the task at hand. Nest takes this a step further using learning algorithms to allow their thermostat to set itself without being programmed by the user. Nest is invisible because the design is literally unseen by the user. Unfortunately, there were reports of users sensing a loss of control with early versions of Nest. Smart technology is great in principle, but sometimes it fails, and when it does, users need to have override control. With the recent Google acquisition of Nest, hopefully these issues will be resolved because the concept of Nest and other invisible devices like it are promising of web design.
