The Web Interaction Model provides you with another way of understanding how Web processes work together. This model accounts not only for hardware, software, and networks, but also for the user's experience. The Web Interaction Model is based on the idea of a series of layers operating dynamically, with each layer responding to input and data from the other layers
The following diagram illustrates the Web Interaction Model:
You should keep in mind that there is overlap between the layers of the model. Each layer represents a discrete element of the Web.
In some cases, elements support the layers above them, but in all cases, each layer is affected by the others. This model makes distinctions among the elements of the Web, so you can consider your options for each element independently when you are clarifying your Web site needs.
Your organization's business goals should drive the choices made at each layer. When planning a Web site, look at more than one element.
Consult all team members for input in their area of expertise. End user satisfaction is affected by every component and layer of your Web site.
What is the difference between the first two layers, Signs and Metaphors and Information Architecture? Answer:
Signs and Metaphors involve visual elements that are experienced immediately when the Web site is displayed, including elements such as icons, symbols, colors, sounds, labels, and animation.
Information Architecture is less visual and more conceptual, dealing with how all the information contained on the site is organized.
The organization might be indicated by icons or other signs, but the structure of the organization is called Information Architecture. In the next lesson, you will learn how the Web Interaction Model relates to other models.
