Levenshtein distance-based posture comparison method for cardiopulmonary resuscitation education

Abstract

Practice-based educations helps trainees to understand the theorical knowledge by lectures easily. However, given that the limited number of trainers, the effect of practice can be reduced. Therefore, the automatic evaluation approaches of practices is demanded. This paper proposes a Levenshtein distance-based posture comparison method for evaluating the postures during cardiopulmonary resuscitation (CPR) practice. The proposed posture comparison method can be extended to the evaluation of consecutive gestures that are consisted of postures.
