PLAZA TORRES, Mauricio. Use of virtual environment and selection of parameters of measurements in the application for the treatment of phobias. Ing. Desarro. [online]. 2008, n.23, pp.10-25. ISSN 0122-3461.

The possibility of discovering some variables that might be measured and of being able to determine the evolution of the patient and the level of the illness in patients with phobias by means of the use of the Vital Signs. The article talks about the efforts to carry out a research with the goal of measuring vital signs on people who are placed in relaxed environment and then compare them with vital sign measured under condition of a artificially environment, by means of the use of equipments of virtual reality and environments of heights and closed spaces. At the end of this research, we are trying to determine if the virtual environment has any influence in the person's psychological change seen through the changes of the controlled vital signs of temperature, cardiac frequency and fundamental frequency of the voice. There are some parameters like the average cardiac frequency, energy of the voice and duration of the voice, which does not allow us to distinguish the reaction of the person in virtual and rest environment. Others parameters like the temperature, cardiac variability and fundamental frequency of the voice let us distinguish the estate of rest and virtual environment. Only the parameter of cardiac variability can be used in the virtual environment of closed spaces and heights. The parameter of temperature and fundamental frequency of the voice are only useful in virtual environment of heights.
