摘要： A frequency modulated continuous wave (FMCW)-based virtual reality (VR) environment interaction system and method are provided. Signal generators (S1, S2, S3) are provided to transmit FMCW signals; a glove is worn on a hand by a user; and multiple signal receiving nodes (H) are provided on the glove and configured to receive the FMCW signals. When the signal receiving nodes (H) receive the FMCW signals, one-dimensional distances are measured by means of FMCW technique; after the distances are measured, positions of the signal receiving nodes (H) in a coordinate system of the signal generators (S1, S2, S3) are calculated; a change in a position of the hand that wears the glove is tracked by means of changes in the positions of the signal receiving nodes (H); and a VR interaction is performed by outputting a change in a coordinate point matrix formed by the signal receiving nodes (H).
