Surfboard somatosensory input and character linkage system

Abstract

The application relates to the technical field of body sense interaction and virtual character control, and discloses a surfboard body sense input and character linkage system, which comprises a board body, a tension detection unit, a posture detection unit and a central processing unit. The system collects cable tension through the tension detection unit, collects an original pitch angle and a roll angle through the posture detection unit, and a decoupling module is built in the central processing unit. A mechanical coupling pitch angle is calculated according to the cable tension and a preset mechanical coupling coefficient, the original pitch angle is subtracted by the coupling pitch angle to obtain a net pitch angle, so that the physical torque interference is eliminated and a speed instruction is generated. Meanwhile, the system dynamically adjusts a roll dead zone threshold according to the tension intensity by using a dead zone module, and identifies a drift state based on a motion time window and a multi-dimensional parameter threshold through a judgment module. The application effectively solves the interference problem of the cable tension on posture recognition, and realizes accurate judgment and stable control of complex combined actions.
