An improved model to evaluate menu hierarchies for mobile phones

초록

This study presents a GOMS based model that can predict the performance time of hierarchical menu interface. In the existing GOMS based models, to predict the performance time of hierarchical menu interface, the prediction models are structured under the assumption that all tasks of selecting an item on the menu are experienced tasks. This study presents a model that can predict the performance time of experienced tasks and that of inexperienced tasks separately. When this model is applied, more accurate prediction of the performance time of hierarchical menu interface of mobile phone that include both the experienced and inexperienced tasks will be possible. This model is designed by measuring the performance time of actual users and the accuracy of prediction is evaluated through an experiment © Springer-Verlag Berlin Heidelberg 2007.
