Vestibular Assessment


The vestibular system contains three fluid-filled canals that crystals can fall into and therefore cause benign paroxysmal position vertigo (BPPV). Various assessment techniques that involve rolling the head into different positions can relocate the crystals and help to treat this problem. However, teaching students these maneuvers can be a challenge due to a lack of resources to help visualize and understand the crystal movement as the maneuvers are being conducted.


The objective of this project is to develop an augmented reality (AR) teaching tool that can enhance instructor demonstrations of the various assessment techniques used to treat BPPV. By creating a 3D interactive model with the vestibular system superimposed onto a head, students are able to better observe and understand how the crystals move as the instructor performs the maneuver using the model.
