Abstract

An unlimited keyboard support is one of the main accessibility requirements for web pages and web applications. But it is not sufficient that the user can perform all actions on the page using the keyboard. In addition designers of web sites or web applications have to make sure that keyboard users can use their pages with acceptable performance. We present GOMS models for mouse and keyboard navigation in web pages and web applications. These models can be used to compare keyboard navigation with mouse navigation. Such a comparison allows us to decide if the amount of keyboard support for a web page or web application is sufficient or if there is an unacceptable disadvantage for keyboard users
