    Dummy Head Tracking Software

    June 10, 2019

    The Dummy Head Tracking (DHT) software (free and open-source) can be used to compute 3D component trajectories of a rigid body from locally-mounted inertial sensors. These inertial sensors include linear accelerometers, angular rate sensors, and angular accelerometers. Even though the software was developed mainly for applications in vehicular crash tests with anthropomorphic test devices (ATD) and the focus was put on the THOR ATD's head (default selection as Body 1 on Screen 1; Figure 1), the DHT package allows for an arbitrary rigid body to be defined as Body 1. As an option, the software enables calculation of 3D component trajectories of an arbitrary Body 2 (e.g. vehicle, ATD’s pelvis, etc.) in the inertial (global) reference system (IRF). When Body 2 is selected, the software computes also the motion of Body 1 in the Body 2's local frame.
