HUMAN COMPUTER INTERACTION
What is Human Computer Interaction?
Human-computer interaction is a discipline concerned with the design, evaluation and implementation of interactive computing systems for human use.
What is Human?
Humans are limited in their capacity to process information.
Information is received and responses given via a number of input and output channels
Visual Channel
Auditory Channel
Haptic Channel
Movement
Information is stored in memory

Importance of HCI
Human reponses: satisfaction, no machine stress
Improve productivity of individuals and organizations - cost reduction, improve support, organizational enchancement
Organization: quality and initiative, flexibility
The importance of User Interface Design
The interface is the the system designer,s way of representing the system to the user
If the interface is confusing, then the user may chose not to use the system at all or will use it incorrectly
At the very least, a frustrating interface can cause stress and discomfort
A well-designed interface can increase productivity
