We have used virtual and augmented reality on different use cases. Most recent project is virtual Street View trip application, which allows users to predefine a trip on Google Maps and engage it in Virtual reality using Oculus Rift.
The idea is that in such way virtual tour of popular and less known places in the world can be organised from any location in the world. The trips can be played back at desired speed with option of pausing at designated points. Each trip can be accompanied by voice of narrator.
