Transcript of Human-computer Interaction

Computer Science, Psychology, Anthropology, Education, Design, Engineering, Math and even Physics. Human-computer Interaction Definition: Human-computer interaction is a discipline concerned with the design, evaluation and implementation of interactive computing systems for human use and with the study of major phenomena surrounding them. Who is involved? The ideal designer of an interactive system would have expertise in a range of topics. However, this is not possible to achieve by one person only, so this is done by a team. What's important? Usability - ability to carry out a task
