document: The development of virtual reality therapy -LRB- VRT -RRB- system for the treatment of acrophobia and therapeutic case Virtual reality therapy -LRB- VRT -RRB- , based on this sophisticated technology , has been used in the treatment of subjects diagnosed with acrophobia , a disorder that is characterized by marked anxiety upon exposure to heights and avoidance of heights . Conventional VR systems for the treatment of acrophobia have limitations , over-costly devices or somewhat unrealistic graphic scenes . The goal of this study was to develop an inexpensive and more realistic virtual environment -LRB- VE -RRB- in which to perform exposure therapy for acrophobia . It is based on a personal computer , and a virtual scene of a bunge-jump tower in the middle of a large city . The virtual scenario includes an open lift surrounded by props beside a tower , which allows the patient to feel a sense of heights . The effectiveness of the VE was evaluated through the clinical treatment of a subject who was suffering from the fear of heights . As a result , it was proved that this VR environment was effective and realistic at overcoming acrophobia according not only to the comparison results of a variety of questionnaires before and after treatment but also to the subject 's comments that the VE seemed to evoke more fearful feelings than the real situation
