Tactility is the space of the interval; acoustic space is spherical and resonant.

Tactility is space of the interval.

As far as the customer is concerned, the interface is the product.

Las interfaces son procesos de filtrado y de unión con los que las ExO construyen puentes entre las externalidades SCALE y los marcos de control internos IDEAS.

An interface is humane if it is responsive to human needs and considerate of human frailties.

The Chinese used the intervals between things as the primary means of getting 'in touch' with situations.

Interaction is the mode of life of living organisms. Each must feed on its environment, ingesting chemicals or other organisms. This is something more than "interaction", it is activity directed towards the environment. Since the organism must be selective in what it ingests, it needs to discriminate among the entities in its environment. From very primitive forms of discrimination, the sensory mechanisms of organisms have evolved into the senses of man, interpreted by an internal cognitive apparatus, memories of past experiences, and an ability to take rational decisions. By "rational" I mean activity that achieves intended results because it is based on a reliable understanding of the nature of the environment. In interacting with each other to carry out tasks jointly, men have further developed language, leading to a shared understanding of the environment. This shared understanding is knowledge.

Recognition that art was located in an interactive system rather than residing in a material object... provid[ed] a discipline as central to an art of interactivity as anatomy and perspective had been to the renaissance vision.

One touches and, in the act of touching, one's touched.

There are no connections in resonant space. There are only interfaces and metamorphoses. (p. 75)

A body can only act immediately on what it is in contact with; it must be by the action of contiguous particles—that is, practically, through a continuous medium, that force can be transmitted across space.

The essence of any interpersonal relationship is interaction. Two individuals may be said to have formed a relationship when on repeated occasions they are observed to interact. By interaction it is meant that they emit behavior in each other's presence, they create products for each other, or they communicate with each other. In every case we would identify as an instance of interaction there is at least the possibility that the actions of each person affect the other.

Touching is a powerful act

Many programs don’t have well-defined interface. They should have.
