Abstract: A wind pressure type of haptic firefighting nozzle interface that is interworked with virtual reality (VR) content for virtual firefighting training is provided. The wind pressure type of haptic firefighting nozzle interface includes: a flow controller for adjusting a spraying intensity of water sprayed on the VR content; a stream shaper for adjusting a spray shape according to a radiation angle of the water sprayed on the VR content; and at least one first haptic device for providing haptic feedback corresponding to the spraying intensity and the spraying shape determined according to control through the flow controller and the stream shaper using wind pressure.
