LinguaPracticaVR is one of those VR products that I tested.
LinguaPracticaVR offers free English lessons in a virtual reality context. LinguaPracticaVR builds short lessons into virtual reality images of places in Ireland and the United Kingdom. For example, in the screenshot below you will see an image of the Powerscourt Waterfall. Within that image there are three short lessons about the words used to describe what is seen in the image.
Applications for Education
LinguaPracticaVR is a still in the early phases of its development, but there is excellent potential for its use as an instructional tool. One thing to note is that it seems to be built with high school age or older ELL/ ESL learners. I say that because one of the tours includes a visit to a pub.
