Usability evaluation of cell phone user interfaces

Abstract

In this study, we investigated usability issues of the SMS sending menu hierarchies and functions of the cellular phones. Individual differences, technological experiences, symbol perception test, previous cell phone usage experiences and SMS sending frequencies of the subjects are observed and evaluated in the laboratory environment. Also, subjects ordered to perform SMS sending according to the well defined scenario. During the implementation of this scenario, SMS sending performances and subject satisfactions are evaluated by help of the inventories. These dependent and independent variables are evaluated with sort of statistical methods. Pearson correlation values and ANOVA results show us that there is a significant correlation between extraversion personality types with SMS sending frequency. Also, we observed that when the SMS sending amount is increased in a day, SMS sending period decreased by help of the learning effect. © 2008 Elsevier B.V., All rights reserved.
