Technology can communicate, but doesn’t need to speak. Create ambient awareness through different senses. Communicate information without taking the wearer out of their environment or task.

A person's primary task should not be computing, but being human. Give people what they need to solve their problem, and nothing more.

A calm technology will move easily from the periphery of our attention, to the center, and back. The periphery is informing without overburdening.

Design for people first. Machines shouldn't act like humans. Humans shouldn't act like machines. Amplify the best part of each.

Does your product need to rely on voice, or can it use a different communication method? Consider how your technology communicates status.

Think about what happens if your technology fails. Does it default to a usable state or does it break down completely?

What is the minimum amount of technology needed to solve the problem? Slim the feature set down so that the product does what it needs to do and no more.

Technology takes time to introduce to humanity. What social norms exist that your technology might violate or cause stress on? Slowly introduce features so that people have time to get accustomed to the product.
