摘要：
Text input is the most common interaction behavior in viture reality（VR）environment，and the mainstream text input is currently realized by laser pointing. However，the existing methods have many drawbacks，such as low efficiency，large jitter，and easy false trigger，which cannot be used to frequently input text in VR environment. Therefore，a novel text input method for VR environment is proposed. First，First, partition the keyboard, use the handle to select the area where the characters are located，and use the word disambiguation algorithm to realize text input in units of words；secondly，perform cluster analysis on the user's click coordinates to do one-key multi-word processing；Finally，three keyboard layouts that conform to user habits are designed，and the optimal layout is determined The experimental results show that the typing speed of the optimal layout is 13.44 WPM（Words Per Minute） with an accuracy of 92.26%，which is a significant improvement compared with other input methods. © 2022 Editorial Board of Jilin University.
