Hi iam xiaoyu zhou. this is my week1-week2 works.
what is HCI?
HCI full name is Human Computer Initiative.
Short for human-computer Interaction, a discipline concerned with the study, design, construction and implementation of human-centric interactive computer systems. A user interface, such as a GUI, is how a human interacts with a computer, and HCI goes beyond designing screens and menus that are easier to use and studies the reasoning behind building specific functionality into computers and the long-term effects that systems will have on humans.
HCI is a very broad discipline that encompasses different specialties with different concerns regarding computer development: computer science is concerned with the application design and engineering of the human interfaces; sociology and anthropology are concerned with the interactions between technology, work and organization and the way that human systems and technical systems mutually adapt to each other; ergonomics is concerned with the safety of computer systems and the safe limits of human cognition and sensation; psychology is concerned with the cognitive processes of humans and the behavior of users; linguistics is concerned with the development of human and machine languages and the relationship between the two.
As computers become more and pervasive in culture, designers are increasingly looking for ways to make interfacing with devices easier, safer and more efficient.
what is Interaction design ?
Interaction design is "the practice of designing interactive digital products, environments, systems, and services." Like many other design fields Interaction Design also has an interest in form but its main focus is on behaviour.(form http://en.wikipedia.org/wiki/Interaction_design)
Interaction design is heavily focused on satisfying the needs and desires of the people who will use the product. Where other disciplines like software engineering have a heavy focus on designing for technical stakeholders of a project.
