An empirical evaluation of graphical usable interface on mobile chat

Abstract

Current text-based mobile group chatting systems hinder navigation ease through long chat archive in a limited screen display. Moreover, tracking messages sent by specific chatter is cumbersome and time consuming. Hence, graphical-based usable interface that aids navigation and message tracking through minimal key-pressed and enhances user expression via avatars employment is proposed. The research outcomes typified that there was significant linear relationship between user interface and usability on text-based and graphical-based usable interface on mobile chat. Moreover, the experimental evaluation results indicated that text-based usability could be improved by creating interface that encourages usages whereas the graphical-based usable mobile chat is augmented by crafting user friendly interface that enhances user satisfaction, encourages usages and promotes navigation ease. The empirical findings and results exemplified that the potential use of graphical-based usable mobile chat as substitution to the text-based that presently has poor reception and is under utilised in commercial arena. © Springer-Verlag Berlin Heidelberg 2007.
