Document Summary

Person s emotions and attitudes about using a particular product, system, or service. Made up of the look, visibility, and feel. The way a user interacts with a system and how this responds to interaction. Color contrast, buttons interactions, touch feedback are examples. Regardless of who makes the software, icons and menus tend to be similar. Look for a similar menu name, like file and edit. Companies reuse the same code in each application. Certain operations are so fundamental to processing that all apps just sue these operations. Consistency provides a strong sense of familiarity with a new application. Means that digital information can be perfectly reproduced or replicated. 2nd copy is made simply by duplicating the sequence of 0s and 1s. The first personal computer (the alto) developed by xerox. Graphical user interface instead of text user interface. Prior words were used to represent functionality instead of pictures.
