Switchable Dual Dial: A Japanese Text Input Method for VR Contents based on Flick Input by Using Two VR Controller

We propose a “switchable dual dial” method for Japanese text input by flick input using two VR controllers in a VR environment. The proposed method is to input consonants by flicking the touch pad of one VR controller with one finger. Next, a vowel is selected by flicking the touchpad of the other VR controller with the other finger to input the letter. Since the above two operations can be performed almost simultaneously, the proposed method is expected to be accurate and quick. This paper reports on an additional 7-day experiment that verified the improvement of the input performance of the proposed method as the user becomes proficient in the operation.
