The use of virtual reality (VR) equipment is becoming increasingly common in people’s daily lives concerning a variety of applications and utilities. Text entry in the VR environment has always been a challenge and a main subject of research in HCI, especially when it comes to human-centered and user-friendly interfaces and implementations. To assist occasional text entry on small VR keyboards without specialised sensing equipment or external devices, we compare a single-finger text entry method relying on pseudo-haptic feedback, and a novel bimanual method that exploits the principles of self-haptic feedback. In a user study (n=24), we find that both methods have comparable performance but also distinct advantages and disadvantages, demonstrating good learnability and promising prospects for further refinement.
