aVOR is a teaching, training, and test tool specifically designed to provide a comprehensive understanding of the vestibulo-ocular reflex (VOR) system and its disorders, including Benign Paroxysmal Positional Vertigo (BPPV). Developed by Hamish MacDougall, this iPhone application serves as an invaluable resource for college-level neuropsychology students and medical professionals.

The application offers a detailed demonstration of eye saccades, including those caused by canalithiasis, which refers to the presence of free-floating particles in the canals. It also showcases both functioning and dysfunctional VOR, shedding light on how head movement influences eye direction and the impact of semicircular canal dysfunction. With its in-depth exploration of canal size, shape, and location in the head, aVOR provides a comprehensive overview of the causes of nystagmus.

One notable feature of aVOR is the Quiz Mode, which allows students to diagnose various types of VOR dysfunction based on presented symptoms. This interactive component enhances the learning experience and facilitates a deeper understanding of the subject matter.

Supported by the University of Sydney, Australia, aVOR incorporates the latest research in the field of neuropsychology. Its user-friendly interface and informative content make it an essential tool for anyone seeking to expand their knowledge of the VOR system and its disorders.
