Title:
FMCW-BASED VR ENVIRONMENT INTERACTION SYSTEM AND METHOD
Document Type and Number:
WIPO Patent Application WO/2021/120971
Kind Code:
A1
Abstract:
An FMCW-based VR environment interaction system and method. Said system comprises: a glove, signal receiving nodes (H), and signal generators (S1, S2, S3). There are a plurality of signal generators (S1, S2, S3) for sending FMCW signals; the glove is worn on the hand by a user, and there are a plurality of signal receiving nodes (H) arranged on the glove and used for receiving the FMCW signals sent by the signal generators (S1, S2, S3). When the signal receiving nodes (H) receive the FMCW signals, a one-dimensional distance, i.e. the distance between the signal receiving nodes (H) and the signal generators (S1, S2, S3) is measured by means of the FMCW technique, after the one-dimensional distance is measured, the positions of the signal receiving nodes (H) in a coordinate system of the signal generators (S1, S2, S3) are calculated, a change in the position of the hand that wears the glove is tracked by means of a change in the positions of the signal receiving nodes (H), and a VR interaction is provided by means of a change in a coordinate point matrix formed by the outputted signal receiving nodes (H), so as to provide a more realistic man-machine interaction mode for the VR system.
