A Japanese Character Flick-Input Interface for Entering Text in VR

要旨

This paper presents new flick input interfaces to improve the usability of Japanese character input in VR space. We designed three different interfaces called TouchFlick, EyeFlick, and RoundFlick, which make use of various controller interactions and eye gestures. To investigate the effectiveness of these methods, we compared them with a conventional VR QWERTY keyboard with ray-based selection. We found that TouchFlick was significantly faster and RoundFlick had a significantly lower error rate for experienced users. On the other hand, the input efficiency was the same as that of the conventional method for those who had no experience with flick input. Regarding subjective evaluation, there was no significant difference in usability and mental workload.
