Therefore, the condition that the escape result of simulating fire escape is escape failure due to the fact that the virtual reality equipment or/and the input equipment are connected by mistake can be avoided; further, the statistical results are affected.
Specifically, step S320 may include: detecting whether the virtual reality equipment is normally connected; if the virtual reality equipment is normally connected, whether the input equipment is normally connected is detected. And if the virtual reality equipment is abnormally connected, directly prompting error information. Therefore, resources can be saved, and the waste of resources caused by the fact that the input equipment needs to be detected when the virtual reality equipment is abnormal is avoided.
