Usability-Optimization of Inertial Motion Capture Systems
Inertial Motion Capture Systems (IMCS) have both many benefits and known disadvantages. The objective of this paper is to optimize available and current IMCS. Therefore the development guideline VDI 2221 was utilized with a focus on the preparation and calibration procedure as well as the attachment of the sensors. The analyzation revealed optimization potential that was considered in the conception phase. The elaborated improvements included new clothes, a suitcase for the storage of attachments and clothes, a fixture for the initialization of sensors, optimized attachments, and a new calibration procedure with a mechanical construction and line lasers. The validation showed that the optimized procedure was clear, the new attachments were more comfortable and had a better grip, the calibration posture was reproducible, and the results of the optimized IMCS were better than the results of the standard IMCS.
