How Do We Solve Human Factors for VR and AR Applications?

Virtual reality (VR) and augmented reality (AR) systems are reaching sufficient maturity that some systems are being used on a regular basis by users and others are close to implementation. There are limitations, however, that have prevented many systems from being truly useful for users. An important limitation is the lack of understanding of human factors issues, such as human perceptual and cognitive limitations, that affect the potential utility of VR or AR systems.
