Abstract:
Objective:To explore a better virtual reality (VR) aviation rescue training mode and equipment platform by comparing the application of VR gloves and handle.Methods:A control study was used. Forty undergraduate students were enrolled by using cluster sampling method in this study. They were averagely divided into VR glove group and the VR handle group. Both groups were respectively trained with VR glove and VR handle based on an aviation rescue script of the craniocerebral trauma in traffic accident and the training effect was analyzed by comparing the assessments between VR training and reality simulation. The assessment were conducted both by VR and actual operation trainings and the content included operation, evaluation judgment, and total training time consumed. After the training was completed, the students of 2 groups were investigated by questionnaire.Results:In the VR assessment, the training time for the VR handle group [(26.94±2.00) min] was lower than that of the VR glove group [(31.23±2.23) min], and the difference was significant ( t=6.42, P<0.001). In the reality simulation assessment, the operation score of the VR glove group [(37.80±7.08) points] was higher than that of the VR handle group [(30.40±6.07) points], with a significant difference ( t=3.55, P<0.001). There was no significant difference between the scores of VR assessment and reality simulation assessment in the VR glove group. The reality simulation operation score of the VR handle group [(30.40±6.07) points] was lower than the VR operation score [(36.20±8.15) points], and the difference was significant ( t=2.55, P=0.015). The reality simulation operation time [(30.25±1.66) min] was higher than the VR operation time [(26.94±2.00) min], and the difference was significant ( t=5.59, P<0.001).The scores of assessing operation diversity and the integration with reality in VR glove group were higher than that in VR handle group ( Z=-4.00, -2.00, P<0.001,=0.045), but the scores of positioning accuracy and button functions were lower ( Z=-2.30, t=5.70, P=0.022,<0.001). Conclusions:VR technology has some advantages in helicopter aviation rescue training, has a broad prospect. As the VR human-machine data exchange equipment, both gloves and handles could bring good training effect even they have their own disadvantages. It is still necessary to improve VR software and equipment, and promote the quality of air rescue training in multiple aspects.
