Exploring the effects of virtual hand appearance on midair typing efficiency
Computer Animation and Virtual Worlds, Volume 34, Issue 3-4, May/August 2023., 2023 Midair typing has gradually become the potential mainstream of virtual reality (VR) typing, as it eliminates the setup of additional hardware devices and provides convenience for portable head‐mounted displays (HMDs). In midair typing, users type on a virtual keyboard while using their virtual hands.
