Holo-BLSD: an Augmented Reality self-directed learning and evaluation system for effective Basic Life Support Defibrillation training

Providing an effective cognitive aid to both lay people and healthcare providers in Basic Life Support and Defibrillation (BLSD) procedures is a relevant educational goal in resuscitation. A self-instruction learning simulation program was developed to maximize learning results, helping to enhance motor skills and the retention of cognitive knowledge, reduce instructor intervention and cost. Microsoft HoloLens technology was used, enabling users to interact with high definition holograms. Holo-BLSD was developed as a mixed reality (MR) self-instruction training environment allowing also assessment, using a standard low-cost CPR manikin to deliver tactile information. The manikin was “augmented” by an interactive virtual environment reproducing realistic scenarios. Learners used natural gestures, body movements and spoken commands to perform their tasks, with virtual 3D objects anchored to the manikin and to the environment. We believe such a project is the first in the domain of BLSD.
