Definition of Model Human Processor (MHP)[1]

The Model Human Processor, developed by Card, Moran and Newell, is a design tool that is used for creating an effective user interface. It draws an analogy between the processing and storage facilities in a computer system with the perceptual, cognitive, memory and motor activities of a computer user. The Model Human Processor describes how a user interacts with a computer system:

A visual or audible stimulus is captured.
Down Arrow
The physical attributes of the stimulus are decoded.
Down Arrow
Response.


Example

A pop up message appears on the screen (perception).
Down Arrow
The user works out the response that is needed (cognitive processing).
Down Arrow
A motor response is initiated (response).
Down Arrow
The mouse is moved and a button is clicked.
