Tracking head-mounted video display (HMD) usage data statistics during a comparative study home trial of low vision enhancement systems


We are conducting a clinical trial to compare the effectiveness of a virtual bioptic telescope in an HMD low vision enhancement system with a wide field of view to currently employed specifications in HMD vision enhancement technology through patient reported outcome measures and usage data analytics. As these systems are being developed and frequently implemented into clinical vision rehabilitation, it is important to evaluate the usage and uptake of these systems with patients’ daily activities. By tracking the usage and magnification specifications of the device, visual function outcome measures may be further explained and correlated.
