Human and Computer can talk?

Computers use 0 and 1 -the binary system which is based on truth table- to execute whatever the user types out. To make it more clear there are some process like complier to interpreter to computer language computers can understand. Actually I am not the expert in this part, but it really has. the KEYBOARD is a medium to make people and computer can communicate each other. i mean keyboard is one of the result of HCI, the study how human interact with computer. It is often regarded as the intersection of computer science, design and several other fields of study. Interaction between users and computers occurs at the interface, which includes both software and hardware.Because human-computer interaction studies a human and a machine in conjunction, it draws from supporting knowledge on both the machine and the human side. On the machine side, techniques in computer graphics, operating systems, programming languages are relevant. On the human side, communication theory, linguistics,and human performance are relevant. And, of course, engineering and design methods are relevant.

Long years ago, looking at the history of HCI as tools people like
–Vannevar Bush: memex
–Doug Engelbart: mouse, GUI, word processing, etc.
–Ted Nelson: hypertext
–Alan Kay: object-oriented programming, laptops

are focused on implements: tools.

Here I have a silly question that which one came first, the egg or the chicken? you would not want to answer that. Then what do you think of this sentence that people often interact with media technologies as though the technologies were people. That is true, though. Some movies inspire people to have better ergonomical technologes, so with develped technology, people can make practical science fiction films.

The last thing, do you know what Ethnomethodology means? According to the ppt simply it means the study of the ways in which people make sense of their social world. Nowdays Ethnomethodology is a fairly recent sociological perspective, founded by the American sociologist Harold Garfinkel in the early 1960s. And Ethnomethodologists assume that social order is illusory. This clss was pretty hard to have a fully understanding, because of lots of confusing concepts and scientific terms. But good thing is, pro.Yoon revises what we've learned in korean before the class is dismissed. Thank you.^^
