Estimation of Interpupillary Distance Based on Eye Movements in Virtual Reality Devices

A mismatch between the interpupillary distance (IPD) and inter-optical system distance (IOSD) in virtual reality (VR) applications can lead to discomfort. The IOSD must be adjustable according to the user’s IPD to solve this issue. In this study, we investigate IPD estimation methods by t...
