Monitoring and Analyzing VR Applications Using the Generic Events Plugin

The Generic Events Plugin has been used for monitoring VR applications. For this, the VR applications have been equipped with a monitoring component, that sends monitored events to the Generic Event Monitor as described here. An example for a monitoring component are the scripts attached to this page. These scripts can be integrated into ​Unity 3D projects. Unity 3D is a game engine that, in addition to others, can be used to create VR applications. One of the scripts must be added to a game object in a VR scene. On initialization, the script starts to monitor head movements of users as well as grabbing and using objects. For this, they register with event handling mechanisms attached to other game objects in the scene to be notified about any interaction. One of the scripts, the one with VRTK in its name, is an extension to the other. It works with the ​Virtual Reality Toolkit (VRTK) and extends the functionality of the other script with framework specific monitoring capabilities.
