Web-Usability

A site must be like any other technical aids meet certain requirements in order to be user-friendly. It is the presentation of the contents of the human capacity to adapt. ( "Do not make me think.")

Perception

By far the largest part of the information about the outside world (about 80%) met the people on the eyes. It is much easier to process information and to retain a well-known structure. Too much information overload the cognitive system. Through abstraction, filtering and detection of the causal relationships are sensory evaluated and sorted. This process is in psychology known as "Chunking." Generally applies to the human memory performance model of the "magic 7" (Miller) applicable. There are interfering factors, which may reduce this figure. It is an intermediate goal to remember, it is perhaps demotivated, in a bad mood, is under stress, is tired, alcohol, etc.. It also extends the memory surfing no further than ca.4-5 screen pages. The average stay three to five units in the conceptual short-term memory.

Design tasks

The task of a web page is always first, the needs of the customer. The customer wants to be informed, entertained, or to buy something. About as good as possible to ensure that the page must clearly convey their content. (Where am I? What does this page? Where have I been? Where can I go?) The information should be in clear hierarchies clear and reasonable multiples. The site has to be fast, because the user is impatient and quick to get information, he wants. The goal is to maximize the processing depth "Depth of Processing" (Craig and Lockhart), as a strong reminder to the seen.

The service is supported by standards, as a firm or a fixed layout simplified terminology. Through the activation already learned approaches to control of technical systems is an intuitive operation.
