In this project, we first recorded the motion positions at equal time intervals using HTC devices. The data was imported into the grasshopper, and the relative velocity of each segment of motion was measured by taking the distance between two points. The motion trajectory and motion velocity were visualized by the different colors of the nodes and the unfolded area of the segmented trajectory.

The mechanism of our project is based on the mechanical motion capture systems which directly track body joint angles and are often referred to as exoskeleton motion capture systems, due to the way the sensors are attached to the body. We attached the skeletal-like structure to our bodies and as we move so do the articulated mechanical parts, measuring the relative motion. Mechanical motion capture systems are real-time, relatively low-cost, free from occlusion, and wireless (untethered) systems that have unlimited capture volume.
