When we use adapters, we are trying to accomplish some kind of goal or need. This kind of gesture comes in three forms: self-adapters, alter-adapters and object-adapters. Self-adapters are gestures that are self-touching movements, such as scratching an itch on our arm or removing something that got into our eyes. Alter-adapters are gestures directed toward someone else; an example of this would be fixing someone’s tie or removing lint from his clothes. Object adapters are focused on objects, like poking holes into a soda can.
