Communicating your mental model to the user: Design models and the system image | Architecting Usability   Leave a comment

AN :  for anyone who uses technology , adapting the uses with the inherent functionality  is either via analysis or by diving in and using the technology.

The better  the intuitiveness of the technology’s design , the quicker its adoptation and the greater the productivity of the user. The article introduces us to the design, system and user model.

To use the terminology popularized by Donald Norman in The Design of Everyday Things, the conceptual model in the designer’s mind is called the design model. The user’s mental model is simply referred to as the user’s model. And the presentation and behavior that the product’s user interface exhibits is called the system image.

And so to design a usable and learnable product, then, the designer’s challenge can be viewed as aligning the design model and the system image, and structuring the system image in such a way that it accurately portrays the design model and enables the user to develop her own user’s model that closely approximates the designer’s model. As the completeness and correctness of the user’s model increases, the user’s skill at operating the application will approach that of the application’s designer.”
