Summary-6

Key point:
-People often interact with media technologies as though the technologies were people.

If we view objects, technologies and natural phenomenon as if they do, in fact, have goals and intentions, then we will design like an artificial intelligence researcher.
On the other hand, if we view objects, technologies and natural phenomenon as if the just look like they have goals and intentions, then we will design like a tool builder for human “users” or “operators” of our tools.

We can find HCI in the history, for example:
Vannevar Bush: memex
J.C.R. Licklider: computer networking, agents
Ivan Sutherland: sketchpad
Doug Engelbart: mouse, GUI, word processing, etc.
Ted Nelson: hypertext
Alan Kay: object-oriented programming, laptops, ...

Where does HCI meet AI?
basic design question: should the computer act like a person?
- agents versus “direct manipulation” even “direct-manipulation” interfaces are based on a “conversation” metaphor: the computer responds immediately to each action or command from the “user” but, there are (at least) two models of conversation information/intention transmission.

- hci lesson from “Sleeper”

1) Reliability
2) Personalization
3) if it isn’t broken, don’t fix it
4) intuitive UI design

A definition of ethnomethodology:
Ethnomethodology simply means the study of the ways in which people make sense of their social world. Ethnomethodology is a fairly recent sociological perspective, founded by the American sociologist Harold Garfinkel in the early 1960s. The main ideas behind it are set out in his book "Studies in Ethnomethodology" (1967). Ethnomethodology differs from other sociological perspectives in one very important respect: Ethnomethodologists assume that social order is illusory. They believe that social life merely appears to be orderly; in reality it is potentially chaotic. For them social order is constructed in the minds of social actors as society confronts the individual as a series of sense impressions and experiences which she or he must somehow organize into a coherent pattern.
