초록
Optimizing text entry in extended reality (XR) is important. However, most studies have focused on inputting alphabetic characters, so there is still insufficient research on inputting Korean characters. As a follow-up to our previous research, this paper deals with the effects of keyboard layout and augmented position on Korean text entry in the XR environment. For this purpose, we developed a virtual keyboard environment using the representative Korean keyboard layout “Du-Beol-Sik” across three augmented positions: mid-air, physical planar surface, and palmar surface. After conducting an experiment, we analyzed the effects of keyboard layout and augmented position on text entry by comparing the results of our previous research (the effect of augmented position on text entry based on the international standard Korean keyboard layout ‘Chon-Ji-In’). The analysis results confirmed that the virtual keyboard performed the best overall when augmented in mid-air regardless of the keyboard layout. It was also confirmed that the keyboard layout had little effect on text entry. Based on detailed analyses, we suggest directions for providing a virtual keyboard for Korean text entries in the future.
