In virtual reality (VR) circles a "cave" is a 3-6 sided box with displays on each side. It has for many years sufficed as the "immersive" portion of VR mostly due to the insufficient head-mounted displays (HMDs) in the domain. However, current HMDs rival many caves and indeed are taking over. Here we discuss the pros and cons of this advent as well as human factors issues related to VR and the use of HMDs.
