Virtual reality (VR) Exposure Therapy with sophisticated technology has been used in the Psychological treatment. The goal is to design a virtual environment using HCI (HMD) device with an interactive and immersive realistic 3D graphic scenes for exposure therapy of acrophobia that allows patient to sense height and gets used to the fearful feelings .The degree of fear is then used to evaluate the effectiveness of the system before and after therapy with the help of comparison. One may feel a little uneasy and perhaps accelerated heart rate, excessive sweating and shortness of breath, etc. are some of the most common physical symptoms of anxiety upon exposure to height. This extreme or irrational fear of height is called "Acrophobia". The HMI based simulation is used which used the body sensation elucidation as physical symptoms of anxiety upon exposure to height to predict the results. The test reveals that anxiety level decreases from 16% at first level exposure and 8% at last level exposure. It is concluded from the results that VR exposure therapy is more effective than real exposure therapy and also the post test for VR exposure therapy were significantly better than post real exposure results. This system provides cost effective solution for rehabilitation environment.
Augmented reality technique (AR) is an emerging method to advance real world (RW) environment or user experience, which is mixed virtual and real reality. It is generally used to support image formation concepts, which is enhanced using relevant equipment. However, the relevant equipment is high-cost, portable, and limited software or hardware equipment, which reduces its potential application areas. Therefore, the aim of this paper is to design an inexpensive platform to determine the customized application using augmented reality, which is based on open-source software and hardware equipment. It is used to advance the targeted platform with several render effects. In addition, three virtual models are selected and applied animation function on its platform, which is controlled using external device such as keyboard and mouse. It is successful, sufficient and inexpensive device to meet the demands in various applications with external control device.
