Implicit interactions could be broken down as: something “that does not require explicit commands from a user, i.e., a system can take appropriate actions to support a user’s primary task or related tasks autonomously.1” This idea is something that is not as fully fleshed out when it comes to computer human implicit interactions because those small interactions often are overlooked and we do not notice them ourselves.
Figure 1 diagram shows a group of people in their physical space coming up with a “context” to start the implicit input implicit output cycle. Within the square is someone who cycles explicit input into a computer system which gives an explicit output. This is repeated and eventually leaves the user with implicit interactions in their day to day. It is not possible without the input of some information though. Human centered computing,“weaves computation and communication technologies into the background of people’s working and living spaces, and changes the interactions between human and computers into implicit mode.2” The prior to human computer interaction was just human-human interaction. The implicit interaction between this group could even be found between a doorman and a passerby. The doorman in Figure 2 is opening the door not because the user is asking him to, but because he knows that the user is part of either the hotel the doorman is working for or the user is entering the car from the hotel. “An interaction designer designing an automatic door can use the doorman pattern to motivate questions such as how the door draws attention to itself, how it communicates its role as a portal, and how it introduces its affordances.3”
