A Japanese input method using leap motion in virtual reality

Various character input devices and methods have been proposed with the spread of VR. However, most of the techniques for character input suffer practical issues such as a slow input speed or many input errors. Although there are methods that can withstand practical use, they require dedicated controllers, and the use cases are limited. In this study, we restrict input characters to Japanese syllabary. This is because the Japanese syllabary is characterized by consisting of ten consonants and five kinds of vowels. High speed blind typing can be realized by utilizing this feature. As the results of experiments, we realized an input speed of 43.15 CPM (Character per Minute) on average for short word input.
