ENTERTAINMENT AND GAMING
In conjunction with gaming and entertainment software, goggles and headsets can insert participants into imagined worlds, turning watching a screen into living an experience. Some VR headsets carry a high price tag, especially for proprietary closed-face designs. Wearing them for long periods of time produces fatigue and an unsettling feeling of enclosure. Producing and supporting VR experiences can demand extensive programming resources above and beyond the basic entertainment experience. If the viewing system lacks the proper spatial cues and fails to accommodate the participant's head movements properly, the participant can suffer from motion sickness. In some cases, VR leads to desensitizing results that interfere with the ability to perceive and react to real experiences, or that encourage the choice of VR over real life.
