This video demonstrates a hybrid collaborative immersive analytics experience we are developing at the VRxAR Labs research group at Linnaeus University, Växjö, Sweden.

Our experience consists of an immersive virtual reality (VR) application, and a non-immersive web application, allowing for synchronous exploration of data through two users: one in VR, and one outside VR.

The immersive application is centered around a room-scale VR setting, using a head-mounted display as the user's visual interface, and 3D gestural input as the interaction interface to operate the application. The non-immersive application is an interactive 2D information visualization that runs in a web browser and can be operated through a normal desktop computer, notebook, and tablet or smartphone device.

For the the purpose of this video demonstration, we illustrate the language variability in Tweets within the Nordic countries from a sociolinguistics perspective. The visualized data were collected within the scope of the Nordic Tweet Stream (NTS), a dynamic corpus of Tweets, a cross-disciplinary project of computer scientists and sociolinguists at Linnaeus University [1].
