Role of Psychology in Human-Computer Interaction -- II

Role of Psychology in Human- Computer Interaction

In my last blog I described the MHP( Model Human Processor).

Now, I will give some examples of the the same.

Example 1: Simple Reaction Time

Production rule "Programming" for simple reaction.

Pattern-action pair :

patterns are tested in parallel 

Actions are performed serially

Push the button as soon as you see the light on display.

Example : Simple Reaction

Cognitive processor uses rule to decide to make response

Motor processor responds to command in working memory.

The MHP is a small picture.

The MHP is an example of how many details can be organized into an architecture for predicting and explaining cognition and performance relevant to HCI

Another example is :: 

GOMS

GOMS is a simpler version of the same approach

(I will explain GOMS in some of my upcoming blog)
