			===Affordance===
			The word "affordance" was originally invented by the perceptual psychologist J. J. Gibson (1977, 1979) to refer to the actionable properties between the world and an actor (a person or animal). To Gibson, affordances are a relationship. They are a part of nature: they do not have to be visible, known, or desirable. Some affordances are yet to be discovered. Some are dangerous. I suspect that none of us know all the affordances of even everyday objects.

			In product design, where one deals with real, physical objects, there can be both real and perceived affordances, and the two need not be the same. In graphical, screen-based interfaces, all that the designer has available is control over perceived affordances.

			The computer system, with its keyboard, display screen, pointing device (e.g., mouse) and selection buttons (e.g., mouse buttons) affords pointing, touching, looking, and clicking on every pixel of the display screen. Most of this affordance is of no value. Thus, if the display does not have a touch-sensitive screen, the screen still affords touching, but it has no result on the computer system. Mind you, the affordance still has impact: it is useful in multiple-person communication, and it helps aid the sale of screen-cleaning tissues and fluids.

			All screens afford touching: only some detect the touch and are capable of responding. But the affordance of touchability is the same in all cases. Touch sensitive screens often make their affordance visibly perceivable by displaying a cursor under the pointing spot.

			The cursor is not an affordance; it is visual feedback.

			===Berrypicking===

			Berrypicking: goal-oriented search with an unfocused and more relaxed mode of browsing. Or rephrased in the context of this article, Berrypicking unites explicit and implicit search modes. The latter is the space which allows users to explore experiment and actively change direction. Therefore Berrypicking is an example of an emerging user journey, that views browsing as the space for discovery, and even serendipity, and as we see later, for implicit learning which supports users’ active creativity.

	While not the most pleasantly named concepts, "The Rat Factor" refers to a principle by which computer users expect consistency in interface/interaction design. In a lab, rats can be trained to push a button in order to receive a food pellet or reward. The Rat Factor describes the optimal state of training a user to return to the same place in order to execute a command in the interface. The Rat Factor principle keeps order in the UI and provides consistency for the end user's experience.

	===~~Fitt~~'s Law===		===Fitts's Law===

	Fitts's law (often cited as Fitts' law) is a model of human movement in human-computer interaction and ergonomics which predicts that the time required to rapidly move to a target area is a function of the distance to and the size of the target. Fitts's law is used to model the act of pointing, either by physically touching an object with a hand or finger, or virtually, by pointing to an object on a computer display using a pointing device. It was proposed by Paul Fitts in 1954.
