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.
