Virtual reality (VR) is a digital environment experienced through a headset. Augmented reality (AR) frequently is based on a three-dimensional image with overlays of text. Augmented reality may be based on an app that provides real information about the environment, such as a map of stars in the sky above. Mixed reality (MR) overlays digital objects on the real world environment. Microsoft leads in mixed reality with the Hololens headset.
In “Future of mixed reality: How augmented and virtual worlds will collide,” Mike Colagrossi describes these technologies and predicts they “will completely change our way of doing things and viewing our world.” Several practical uses are described, including overlaying an ultrasound or xray image on a patient during surgery, collaboration in design, and drones sending quantifiable information about the world while in flight.
Kevin Siegel briefly explains how to create virtual reality with Adobe Captivate 2019 and shows an example in “ADOBE CAPTIVATE 2019: Virtual Reality Is Literally Here!”.
In “Realities: Why AR over VR,” Clark Quinn explains his preference for augmented reality over virtual reality. Augmented reality is “an annotated world” that may “spark more ubiquitous learning” and seems to have “less physical overhead.” Virtual reality allows for creating an entire world, which can provide practical value when that world is, for example, microscopic. Mixed reality allows for creating an experience that becomes part of the real life of participants, for example, a business scenario where learners respond to situations by email.
