Usability taxonomy and context-of-use taxonomy for usability analysis

The interest in developing usable products has led to the inclusion of usability aspects in product development processes. Generally speaking, the literature tends to define usability in overly brief and ambiguous terms and to describe its application in informal terms. Also there is a tendency to overlook characteristics of the context in which a product is to be used, and this usually means that the usability of a product in its operational environment is often diminished. For these reasons we propose in this work a detailed taxonomy which contains exhaustive descriptions of usability attributes, and a comprehensive taxonomy that describes context of use and its attributes by means of precise definitions.
