It is often regarded as the intersection of computer science, aesthetics , teleology , design and several other fields of study. Interaction between users and computers occurs at the user interface (or simply interface), which includes both software and hardware, for example, general-purpose computer peripherals and large-scale mechanical systems, such as aircraft and power plants. HCI used at various fields. First, There are people using HCI as tools. For example Vannevar bush made memex. Second, There are people using HCI as systems. For example Macintosh powerbook was made in 1991. Third, There are people using HCI as funding. For example Military: Navy, Air Force, ARPA, DARPA. Another simple example is using webcam. Eliza is answer machine with human. But It doesn't answer everything. It does (or does not) behave like a huma...

In this week, we learned about 'Artificial Intelligence'. We knew a person, Alan Turing, who was known as founder of computer science, artificial intelligence, mathematician, philosopher, codebreaker, and a gay man. He dead early by suicide but he leave many works. one of them is imitation game. It is game to guess sex by only text. The result is exciting. No one predicts his/her sex only text. Turing thinks man acquired sex by environment. He says that gender. Gender is changed anytime. The second imitation game is that. Who is man or machine by text as before . The result is same too. So he thinks that Can MACHINE do think?? Marvin Minsky define AI as the science of making machines do things that would require intelligence as if done by humans. AI have many research areas : Knowledge Representation ,Programming Languages,Natural Language (e.g., Story) Understanding,Speech Understanding, Vision, Robotics, Machine Learning, Planning etc. AI is planning as a technical problem. G...

In this week We learn about social network in various angle. There are many network anywhere our background. Social networks have been more concerned by experts in various field in comparison with past. Thus Recently they contributed to an understanding of social networks too.
