ThermoReal_F1 is a VR training suit with hyper-realism that delivers safe, cost-effective, experiential, and risk awareness for firefighters. In real firefighter training, there are lots of limitations on the training space. However, ThermoReal_F1 can get rid of this obstacle since the training is conducted in virtual reality. ThermoReal_F1 enables the trainer to take the live fire training ground into the classroom. One of the benefits of this suit is that the trainer can feel the real temperature in VR. Also, it reduces carbon emissions and water consumption (Eco-friendly). Not only that, it increases the training capability at a lower cost.
