OORT: An Air-flow based Cooling System for Long-term Virtual Reality Sessions

In this paper, we present OORT, a cooling system for head-mounted displays (HMDs) that improves wearing comfort by decreasing skin temperatures of the facial areas covered by the headset. The integrated cooling system consists of an electronically controlled fan blower. The fan compartment is integrated into an hmd padding element with custom-designed air flow channels that provide cool air circulation around the covered facial regions. We report on the design and implementation of OORT as a viable way to provide thermal comfort during long-term virtual reality experiences.
