Abstract

In recent years, extended reality (XR) devices have been developed into see-through HMD (Head Mounted Display) with bare-hand interaction. Previous studies on inputting text based on bare-hands in XR were mainly conducted using virtual keyboards, but most of them focused on inputting alphabetic characters, so there is still insufficient research on inputting Korean characters. In addition, virtual keyboards in previous studies were mainly augmented in mid-air, thus various augmented positions were not considered. Therefore, this paper presents a study on augmented positions for inputting Korean text in the XR environment. For this purpose, we developed an experimental environment for three augmented positions (mid-air, physical planar surface, and inner surface of the palm) based on the international standard Korean keyboard layout and analyzed its effects on text entry through an experiment. From the analysis results, it was confirmed that the virtual keyboard performed the best overall when augmented in mid-air.
