Windtherm Fire: An MR System for Experiencing Breathing Fire of a Dragon

We present an interactive MR system in which hot wind is sent to a player’s face synchronously to the virtual environment. The system uses a VR accessory called Windtherm, which is attachable to a HMD, heats the air inside, and blows the wind with changeable forces and directions. We improve the device to work interactively to the virtual events. We also develop an MR content in which a player interacts with a small dragon and occasionally receives its breathing fire with simultaneous tactile stimulus of actual wind for enhancing the sense of presence in this fictitious world.
