Feasible mid-air virtual reality with the immaterial projection screen technology

The immaterial projection screen is an emerging display technology that enables high-quality projected images in mid-air. It can be extended to virtual reality (VR) and augmented reality (AR) mid-air displays. In order to make such mid-air VR and AR displays feasible, unobtrusive and low-cost user tracking solutions are needed. In this paper we present such feasible desktop VR and AR mid-air displays.
