MOPED25 | Biomechanics Lab | NC State ISE


General Description

Moped25 is the acronym for Multimodal Occupational Posture Dataset. The dataset includes 25 tasks that are commonly seen in the workplace. The full-body 3-D kinematics data (37 markers) and the synchronized videos were collected in our Biomechanics Lab and all made publicly available on this site.

Subjects and Tasks

  • 12 subjects were included in this project. The first subject was for the pilot test with different marker attachment. The other 11 subjects were using the same marker attachment.
  • 25 different tasks were involved in this project. The following figure shows examples:

  • For the detailed description of the experiment, please refer to our paper in the reference section.

Data Accessing Instructions

  • The marker data were stored as .mat files. Basic loading and visualizing functions are provided in MATLAB code. Please visit my GITHUB page for further instruction.
