Paper Abstract:
|
One of the most important keys in user interfaces design and evaluation is how to measure usability. A wide variety of
usability methods classified into effectiveness, efficiency and satisfaction have been proposed to measure usability. We
propose a new preliminary usability method based on probabilities which estimates how likely a user could find the
information he is looking for on the web. This method could be included in the group of effectiveness. There are many
usability variables that could have an influence where some are subjective and others objective. In this paper we decided
to focus the method on four objective variables of usability which are the amount of information per screen, position on
the screen, position inside the menu and number of steps. We considered this usability variables due to the following
reasons respectively: their impact at first sight, users tend to find the information in certain areas on the web site like
some common web objects, the variation in menu length could aid decision time and decrease the number of errors in
information retrieval, and because as much deeply the information is the user could get lost easily. |
