Abstract

Multi-touch interfaces are becoming popular as a new input means for the various applications. In this paper, we suggest a new Korean text entry method using a multi-touch interface called MPT (Multi-Point Touch) input method. We conducted a text entry performance test comprising 4 sessions for 10 participants, and compared the result with an existing commercial SPT (Single-Point Touch) input method. The experimental results show that the entry speed of MPT was slower than that of SPT method in the initial session. However, the entry speed of MPT input method was improved more rapidly than the speed of SPT method as sessions were proceeded. We observed a statistically significant learning effect from the result of MPT method. Moreover, we found no significant difference between the task loads of SPT and MPT input methods.
