The purpose of this study is to investigate the usability and user interface of different display sizes for smart phones. For this purpose, two different display sizes and two different operating systems were used. Estimation values and observation values were calculated using the key-stroke level model (KLM) for 11 functional factors. The processing times were decreased when a large display size was used, but this tendency did not have statistical significance. There was no difference in the processing times when different types of operating systems were used. Nevertheless, some character input tasks showed a little shorter processing times with large display size than with an ordinary display size.
