Abstract
A method and a corresponding apparatus for mitigating motion sickness in a virtual reality VR/augmented reality (AR) system using a head mounted display (HMD) are disclosed. The method comprises receiving data from a sensor indicating a current orientation of the HMD in real space, and superimposing a visual indication on a display of the HMD. The visual indication provides visual information to a user of the current orientation of the HMD in real space. Furthermore, methods and corresponding apparatuses are disclosed of calculating gaze convergence distance in an eye tracking system, and of gaze based virtual reality (VR)/augmented reality (AR) menu expansion.
