4/23&4/25 Human-computer interaction


We used all about machine that usually has A.I?
what a wonderful world!
and what's that means "HCI?"
where does "HCI" meet "A.I"?

key point


People often interact with media technologies as though the technologies were people.
–related ideas
Clifford and Nash, “the media equation”
Freud, transference
–see also Sherry Turkle on computers as “second selves” and as “evocative objects”
surrealists, “automatic writing” (recall Tristan Tzara’s “recipe”)
Mannheim/Schutz/Garfinkel, the “documentary method”


related points: ethics

questions of ethics and “others”
–should we treat technologies as people or people as technologies?
–should we only treat others who are like us with care and respect? or, should we also extend our care and respect to others who are radically different?
–what makes believe someone or something is alive, thinking, or simply the same as us?


history of HCI as tools: people

people:
–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, ...



basic design question: should the computer act like a person?
–agents versus “direct manipulation”
e.g., Ben Schneiderman versus Pattie Maes (sigchi, 1997)
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
inspirations for ai: e.g., Paul Grice, pragmatics
–co-construction of meaning
ethnomethodology: e.g., Harvey Sacks, conversation analysis
Boring? ok.. let’s watch some movie related to HCI generally.
–hci lesson from “Sleeper”
»1) Reliability
»2) Personalization
»3) if it isn’t broken, don’t fix it
»4) intuitive UI design
