Virtual Reality Training for Police Officers: A Comparison of Training Responses in VR and Real-life Training 3 55 smoke bombs and started shooting at the building to gain access. The police officer (roleplayer) who left the police car appeared to be shot and acted seriously injured. The participants’ task was to control the situation (e.g., attend to the injured officer and protect the lawyer). The training instructors who oversaw the training session were in charge of ending the scenario, typically as soon as the suspects were arrested or the threat was stopped. Virtual reality scenario-based training (VR SBT) The VR system used in this experiment was provided by RE-liON (www.re-lion.com). Participants were equipped with RE-liONs’ Blacksuit consisting of a binocular head-mounted display (including microphone, sound effect, radio chatter), a smart vest with full-body tracking, a computing box (backpack style), and replica rifle. Figure 3.1 shows the VR equipment used in this study. In addition to the VR equipment, there was one VR system operator and two police instructors guiding the training. To ensure the safety of the participants and avoid falls, collisions, and limit the occurrence of cybersickness, the participants were instructed not to run during the VR SBT. Figure 3.1.
