The paper aims to solve the problems in motion design of virtual reality simulation platform, such as high technical threshold and difficulty in flexible editing of motion, optimize the motion design process, and improve the design quality of motion designers. Following the existing virtual reality simulation platform action editing process and demand analysis, a non-parametric VR simulation platform motion editing system is proposed. The functional architecture, operation flow and software interface of the motion editing system are designed to realize the nonlinear editing of VR simulation platform motion design and the visualization of key information. The motion editing system can not only improve the operability of the design but also effectively improve the quality of motion sensing design. The motion editing system can not only improve the design operability, but also effectively improve the quality of motion sensing design, which proves the effectiveness and feasibility of the new system. At the same time, the differences of design ergonomics evaluation between novice and expert somatosensory designers when designing with different systems are discussed, which provides reference and technical support for VR somatosensory design research.
