Midterm Review

Interaction

2. Terminologies (Chapter 1)
HCI is a multi-disciplinary field: computer science and technology, psychology, graphic design, etc.
HCI= {Craft, Science}
Ergonomics, Human Factors, Man-Machine Interaction, etc.

3. Memory (Chapter 1) There are three types of memory function:
Sensory memories
Short-term memory or working memory
Long-term memory
Attention
Rehearsal

4. Deductive Reasoning (Chapter 1)
Deduction:
derive logically necessary conclusion from given premises.
e.g. If it is Friday then she will go to work
It is Friday
Therefore she will go to work.
Logical conclusion not necessarily true:
e.g. If it is raining then the ground is dry
It is raining
Therefore the ground is dry

5. Inductive Reasoning (Chapter 1)
Induction:
generalize from cases seen to cases unseen
e.g. all elephants we have seen have trunks therefore all elephants have trunks.
Unreliable:
can only prove false not true
… but useful! .

6. Donald Norman’s model (Chapter 3)
Seven stages
user establishes the goal
formulates intention
specifies actions at interface
executes action
perceives system state
interprets system state
evaluates system state with respect to goal
Norman’s model concentrates on user’s view of the interface

7. execution/evaluation loop
system
evaluation
execution
goal
user establishes the goal
formulates intention
specifies actions at interface
executes action
perceives system state
interprets system state
evaluates system state with respect to goal

8. execution/evaluation loop

12. four golden rules for design
knowing where you are
knowing what you can do
knowing where you are going (or what will happen)
knowing where you’ve been (or what you’ve done)
