Currently, the text entry method of the portable information devices including smart phones and tablet, is a soft keyboard that appears mainly in the viewing screen. It considered the limited screen of portable information device is inefficient. This paper proposes a gesture-based text entry method which does not require predetermined area. It can be available anywhere on the screen, thus touch type entry is possible. This method is based on the property of Japanese Hiragana-50-phonemic-table and two step sequence of finger gesture is utilized. The first step gesture corresponds to the row entry such as “a ka sa ta na”. The second one corresponds to the column entry of it, such as “a i u e o”. From the experiments, the proposed entry method is easy to learn and entry speed is acceptable. The experimental results show that the proposed method is practically applicable as a new text entry method.
