In-vitro study of mastication process is beneficial for dentists, physiotherapists, and the food industry. Robotic platforms can aid such study by mimicking a human-like chewing pattern for which capturing chewing trajectory of human subjects is an essential step. This chewing trajectory is required for analyzing kinematics, dynamics, and control of the chewing robots. In this paper, a novel motion-capture system using ArUco markers is proposed to capture mandibular movements of a human subject. The proposed system allows for a low-cost alternative for conventional optical motion-capture systems with simpler experimental setup. Using the proposed system, the incisal chewing trajectory of a human subject is captured, the head movements are compensated, and lateral, superoinferior, and anteroposterior mandibular movements are reported.
