Webizing collaborative interaction space for cross reality with various human interface devices

Recently, web based cross reality (XR) concept embracing virtual reality (VR), augmented reality (AR), and mixed reality (MR) technology has emerged, but user interaction devices for collaborative work supported in web environments are limited. The Virtual-Reality Peripheral Network (VRPN) in the traditional VR environment provides a device-independent and network transparent interface. To promote the development of web based XR applications, a common method is required to support a collaborative interaction space in VR, AR, and MR contexts according to the user environment and various interaction devices that can be used without limitation of XR content in web based XR environments as well. In this paper, we propose a webizing method for a collaborative interaction space that provides user authentication and manages user sessions in XR environments. In addition, the webizing method supports human interface devices and related events via an interaction adaptor that delivers events based on user session and converts event messages according to XR content types such as VRPN messages, X3D sensor data, and HTML DOM events to deal with interaction events.
