The use of Keystroke-level model (KLM) to predict mobile phone operating behavior of Korean text was discussed. The KLM model has six operators but only two operators, K & M, were used for the evaluation of different text entry interfaces. The time for keystrokes (tk) was calculated with the Fitts'-law-based-model. The results show that the model well represents the Korean phone-operating behaviors with the significant statistical test of the average time difference of 6.6%.
