Abstract

The purpose of this study is to investigate the usability and user interface in different types of mobile phones. KLM(key-stroke-level model) model estimation and observation values were calculated to perform 11 functional factors in 4 ordinary mobile phones and 4 smart phones. In results, it was found that the usability of ordinary phone is superior to smart phone in basic and simple function likes phone call. On the contrary, the usability of smart phone is superior to memorizing and picturing function. Current results can be used to anticipate the future effort to improve user interface design especially in smart phone.
