Diagnosing knapping skill

The data has been collected as part of the Hand to Mouth project (European Commission FP 6 (NEST Pathfinder), Project 29065). The data was collected by: Dr Blandine Bril, Groupe de Recherche Apprentissage et Contexte, Ecole des Hautes Etudes en Sciences Sociales (EHESS)Dr Robert Rein, Groupe de Recherche Apprentissage et Contexte, EHESS Dr Tetsushi Nonaka, Groupe de Recherche Apprentissage et Contexte, EHESS Dr Francis Wenban-Smith, Dept of Archaeology, University of Southampton Dr Gilles Dietrich, Université René Descartes - Paris 5 The data includes kinematic data from four markers from 18 participants. M1 (Hand) - M2 (Forearm) - M3 (Upper arm) - M4 (shoulder) collected during stone knapping striking movement using a Polhemus Liberty electromagnetic motion tracker system recording at 240Hz.
