Preface: The Case for HCI Design Patterns Twenty years ago, Christopher Alexander shook the architectural world with his landmark book The Timeless Way of Building. The patterns that he and his colleagues defined -- published in a second volume, A Pattern Language -- are an attempt to codify generations of architectural wisdom. For example, he recommends using the "Entrance Transition" pattern with homes or any other building that "thrives on a sense of exclusion from the world.
" "Make a transition space between the street and the front door. Note that the pattern is not just proscriptive. We badly need the benefits of such a pattern language in the field of HCI design.

Usability is the ease of use and learnability of a human-made object. The object of use can be a software application, website, book, tool, machine, process, or anything a human interacts with. A usability study may be conducted as a primary job function by a usability analyst or as a secondary job function by designers, technical writers, marketing personnel, and others. It is widely used in consumer electronics, communication, and knowledge transfer objects (such as a cookbook, a document or online help) and mechanical objects such as a door handle or a hammer.
Usability includes methods of measuring usability, such as needs analysis[1] and the study of the principles behind an object's perceived efficiency or elegance. Introduction[edit] The primary notion of usability is that an object designed with a generalized users' psychology and physiology in mind is, for example: In the user-centered design paradigm, the product is designed with its intended users in mind at all times.
