Traditionally, people have interacted with things like elevators, thermostats, security systems and door locks by pressing buttons, adjusting dials or using a smartphone app. Technologies are emerging so that the need to control these items in the same way may change. You may soon be able to give them cues without making those  physical interactions.  One might define these emerging technologies as  “user interaction technologies” or “touchless interaction technologies."

We want to explore the ways that people can prompt these technologies to complete actions, whether it's  calling an elevator that takes you to the correct floor, the hotel or home door unlocking for the right person, or knowing what room temperature makes you comfortable. We want to understand how we can easily let a user recognize that the technology is present and know how to prompt the technology.

You didn't have to touch them, and you didn't consciously think about whether you were about to walk face first into a door.
