Virtual and augmented reality technology enables us to create unprecedented experiences, for example to meet people for work or fun in digital spaces. Users of this technology, however, would greatly benefit from enhanced visual comfort and perceptual realism of emerging XR displays. Moreover, the technology components developed for wearable computing systems can also augment human performance, for example by helping people see better or potentially improve their cognitive performance or sleep behavior. In this talk, we will discuss several ideas and emerging technologies that strive towards human-centric XR.
