INTERFACE AND ITS METAPHORS What is an interface?
is a device capable of securing the exchange of data between two systems.
is a kind of physical bridge that connects two systems.
generates a bidirectional exchange of information between the two systems.
1984: First computer-based graphical operating system in the desktop metaphor.
1987: IBM internal document defines the interface of a program with "an instrument through which men and computers communicate with each other."
80's: as a tool interface.
1995: Apple: 'rules and conventions by which a computer system communicates with the operator. " note that while maintaining the idea of \u200b\u200bsharing information interface is no longer considered a hardware device but a set of processes, rules and conventions that allow communication between man and machines
digital Pierre Lévy, 1992: "cognitive network of interactions."
Conclusion: There is no unambiguous definition of interface. Therefore turns out to be a wildcard interface semantics, a concept-umbrella.

2. Interface metaphors
The metaphor is necessary to understand things around us.
are effective rhetorical devices of persuasion.
Borges: if metaphor is well done is not noticeable.
The disappearance of metaphor leads us to believe that they, too, as the interfaces suffer from the syndrome of transparency. Eco
: the metaphor is an instrument of understanding additive.

2.1. The conversational metaphor
human beings and computers are considered as partners in a dialogue. Interfaces
alphanumeric (command interpreters).
Project: machine dialogue with men.
Apple GUI, the proposed change: dialogue with smart objects.

2.2. The man and its extensions: the metaphor instrumental arise
operating systems characterized by a graphical environment interaction (Macintosh, Windows, OS / 2). The spread of the proposed graphical interfaces direct manipulation of objects on the screen. The digital world is about millions of users.
New metaphor: the metaphor of the instrument.
"It allows people to feel they are directly controlling the objects represented by the computer."
McLuhan: the media are extensions of our nervous system. Prosthetics
invisible: Mouse, extending our hand.

2.2.1. Transparencies
transparent interface: allows a task without having to operate at lower levels of operation of the machine. You forget
interface and focuses on the work to be performed.

2.3. The interaction space: the spatial metaphor
"Humans use language not only actually live in it," says Castoriadis.
The interface is the site of interaction. Perspective
theater: the interface is transformed into a "staging" in which the designer assumes the role of director.
Critical approach:
instrumental metaphor does not contribute to the theoretical reflection on interactivity. Exacerbated instrumentalism leads to an epistemological obstacle.
conversational metaphor has been applied in a superficial way, users do not talk. Participate in a "conversation" with the drill the designer. Tendency to hide behind the interactive device simulated natural.
