Modelessness – a mode is a state in which the computer produces a different output for the same input than it would have if it were another state the classic example is the keyboard's " caps lock" key.Raskin also advocates a number of changes to conventional interface design. All are intended to minimize the amount of time required for the user to perform any specific task. Raskin includes a chapter demonstrating four models of quantifying the efficiency of a software interface: the GOMS keystroke model, Raskin's own efficiency measure, Fitts' law and Hick's law. Many of the ideas presented in the Canon Cat and The Humane Interface were later adopted by Raskin in his Archy project, and later by his son Aza. The Canon Cat is often considered the first information appliance. Raskin often refers to the computer he designed, the Canon Cat, as an example of a system that implemented the various measures he advocates. The overriding theme is that current computer interfaces are often poor and set up users to fail, as a result of poor planning (or lack of planning) by programmers and a lack of understanding of how people actually use software. The book puts forward a large number of interface design suggestions, from fairly trivial ones to radical ones. It covers ergonomics, quantification, evaluation, and navigation. The Humane Interface: New Directions for Designing Interactive Systems ( ISBN 7-6) is a book about user interface design written by Jef Raskin and published in 2000.
