When studying about the interaction you have to read on :-

1.Interaction Models

• Norman's Model of Interaction (Refer: http://everything2.com/e2node/Norman%2527s%2520model%2520of%2520interaction).
• Abowd & Beale Framework (Refer : http://projects.cs.luc.edu/comp390-490/hk/HCI/theory/abowdfig4/view)

Computer

A Computer system is made up of various elements. As an UI Engineer you have to have an idea about each of the element of the computer that affects the interaction. Those are:-

1. Input Devices
2. Output Devices
3. Virtual Reality
4. Physical Interaction
5. Paper
6. Memory
7. Processing
   

What is Human Compter Interaction

Human Computer Interaction is the base of the User Interface Engineering.

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.

when studying about this Human-computer interaction we could organize the subject in to the following categories.

1. Human
2. Computer
3. Interaction Design Basics
   
4. The Interaction
5. Design Rules
6. User Support
7. Implementation Suppor

Human

When studying the human as an UI engineer you have to pay your consideration on the following.

1. Vision
2. How human Interpreting the signal?
3. How Human read?
4. How Human Hear?
5. Memory of Human
6. Thinking
