The virtual keyboard in the VR space is characterized by the user can place the keyboard at any position and angle in the air. The user’s posture changes as the position and angle of the virtual keyboard change. We conducted an experiment to investigate the effects of the position and angle of the virtual keyboard on text entry. We found that the position of the virtual keyboard affected the workload by analyzing the experimental data for each participant in the experiment. In this paper, we analyzed the experimental data for each entry phrase. The results show that the entry speed and usability may be improved by tilting the keyboard toward the back from the user’s point of view. Furthermore, since the fatigue of the arms was larger than the fatigue of the neck, the fatigue could be minimized by designing VR applications so as to place the user’s fingers at a lower position than the user’s eye level.
