Summary Frontal chewing patterns have been classified in a manual and visual way on recorded movement tracks. The main aim of this study was to use a chain code method to extract the direction and curvature features of the tracks in the frontal plane. The test results indicate that the chain code can stand for the direction and curvature. The chewing movement tracks in the frontal plane can be clustered into chain code values. The method therefore appears to be useful in the classification of chewing movements.
