1. Human Computer Interaction HCI

2. In the last 20 years, the introduction of the graphical user interface (GUI) has revolutionised the ways in which users interact with computers, known as human computer interaction (HCI). After completing this unit, you should be able to achieve these outcomes:

3. Know about the impact of HCI on society, economy and culture. Understand the fundamental principles of interface design Be able to design and produce simple interactive computer input and output based on HCI principles Be able to compare and contrast, using HCI principles, the effectiveness of different designs of input and output.

4. Development Probably the most recognised graphical user interface (GUI) is that used on PCs (personal computer) Probably the most recognised graphical user interface (GUI) is that used on PCs (personal computer) Microsoft Windows was based on the earlier Macintosh model. Microsoft Windows was based on the earlier Macintosh model. Windows version was introduced in the mid-1980s. Windows version was introduced in the mid-1980s.

Command Line Editor DOS, operating system – C:\ prompt would appear on the screen, the user could create a structure such as copying, renaming and moving files (my computer) DOS, operating system – C:\ prompt would appear on the screen, the user could create a structure such as copying, renaming and moving files (my computer) However with CLE, typed text was ignored until the Return key was hit; then the computer interpreted the command and a response appeared on the screen (or not!)

8. Apple In 1984 the Macintosh computer appeared In 1984 the Macintosh computer appeared GUIs in the form of a computerised desktop, icons that were images, files, rubbish bin with the addition of a mouse, enabling the user to locate documents and put them in the bin and click on them to open them. This desktop design has truly influenced how users interact with computers today
