Virtual and Augmented Reality

Virtual reality (VR) and augmented reality (AR) allow individuals to transcend physical constraints and communicate in a space where transformations of one's self-representation and surroundings are effortless and free. In this entry readers will be introduced to the technological components of VR related to tracking, rendering, and display that make such transformations possible. Readers will also gain a deeper understanding of two concepts that are critical to the virtual experience: immersion and presence. The entry highlights the differences between VR and AR and describes the theoretical and practical applications of VR in fields such as nonverbal, health, speech, and environmental communication. Future areas for research and the ethical implications of VR and AR are also discussed.
