Popis: Objective: The aim of this study is to give interest about usability of cellular phone keypad for left-handed person. Background: Although there are being a lot of attempts to design suitable product on user's request in process that design cellular phone keypad, ergonomic access about left-handed person who compose decimal class is unprepared. Especially, in early user's occasion, left-handed persons need more efforts than right-handed person to master Hangul character input process skill level. But, since realization about this left-handed person's discomfort has not spread, the importance has not been well thought in the society. Method: (1) After extracting emblem to use in comparison in questionnaire, applied emblem uniformly to different 3 kind of cellular phone. (2) Measured Hangul input time and mistyping number by dominant hand's position and skill level to reagent. (3) Taking the result through ANOVA. Conclusion: In the result of the experiment about Hangul input time and mistyping number according to dominant hand's position and skill level, left-handed person's group on the low skill level has shown the dullest use capability among 4 experiment groups. Application: In the future, analysis result may be used to the data of realization conversion in process design of various products including cellular phone keypad to consider left-handed person.
