KINMET is an open-source, integrated graphical user interface (GUI) software tool designed to accelerate the computation of head injury indicators from six-degree-of-freedom kinematic data. The software provides a comprehensive workflow for processing raw six-degree-of-freedom measurements, enabling computation of widely used biomechanical injury metrics, including Head Injury Criterion (HIC 15 , HIC 36 ), Brain Injury Criterion (BrIC), Gadd Severity Index (SI), peak resultant linear acceleration and angular velocity, estimated neck forces and moments, and Neck Injury Criterion (Nij). The interface supports selecting data start rows, unit conversion, and configurable signal-filtering options (CFC, Butterworth, Savitzky-Golay, moving average). KINMET automatically generates multipage PDF reports containing summary tables, time-series plots, HIC windows, BrIC and probability curves, neck-load histories, and methodology documentation in addition to a JSON metadata file that is exported for reproducibility. Additional capabilities include live signal preview during the data import stage, automated calculation of sampling frequency, detection of impact event windows, and recommendations for filter parameters based on signal characteristics. This integrated solution addresses the need for accessible, standardized head injury assessment in biomechanics research, automotive safety testing, and sports biomechanics and injury research applications.
