4GAIT: Synchronized MoCap, video, GRF and EMG datasets: Acquisition, management and applications

Abstract

Presented is the 4GAIT, a group of multimodal, high quality Reference Human Motion Datasets. The described in this article Multimodal Human Motion Lab provides a comprehensive environment for multimodal data acquisition, management and analysis. Introduced is a proposed PJIIT Multimodal Human Motion Database (MHMD) model for multimodal data representation and storage, along with Motion Data Editor - a toolkit for multimodal motion data management, visualization and analysis. As an example a group of three synchronized, multimodal, motion datasets using MHMD model: 4GAIT-HM, 4GAIT-Paarkinson and 4GAIT-MIS are described. Comparing to the currently available Human Motion Datasets, 4GAIT offers multiple data modalities presented within a unified model, higher video resolution, and larger volume of motion data for specific medical tasks, which better fulfills the needs of medical studies and human body biomechanics research. © 2014 Springer International Publishing Switzerland.
