Compare virtual reality and augmented reality systems for claustrophobia from HRV

Claustrophobia is certain type of anxiety disorder on closed space. Claustrophobia patient, under certain conditions, for example, elevator, railway carriage or passenger compartment, might be attacked by panic disorder, or panic disorder might occur in very high probability. Flood method is a traditional therapeutic method for anxiety disorder. It is similar to system sensitivity-reducing method, but different than it is that in flood method and in the very beginning, the strongest anxiety stimulus is given so that the anxiety of the patient can reach a peak. This is to train the tolerance from the patient on the anxiety event, hence, when the patient meets slighter anxiety event, the patient won't feels that anxious. This research focuses on traditional diagnosis method of claustrophobia. It will associate virtual reality technology and game technology to develop immersion virtual reality training task, meanwhile, it will investigate if in virtual reality and augmented reality situation, people's anxiety situation can be similarly triggered. Comparisons between virtual reality and augmented reality systems are made via measurements of heart rate variability, technology acceptance model and anxiety assessment
