Virtual reality software & technology
After reading a the book ‘Virtual reality software & technology’ By Gurminder Singh, Steven K. Feiner, Daniel Thalmann. This source analyses how VR has the potential to relax a subject using physiological terms. It states that ‘urban workers are exposed to many kinds of stresses such as long commuting time, human relationships in the company, or troubles caused by the job itself.’ It later states that VR is ideal to help the subject feel less fatigued as opposed to relaxing them mentally, what I originally intent to do when I started this project.
They later presented this concept graph that demonstrates how to make the subject feel refreshed by lowering the person’s active status to the point where they just fall asleep. They also refer that using VR technology can achieve this as it can allow the subject to virtually experience something they can’t in reality. For instance, experimented on a handful of people who suffers from a lot of stress and came up with the stages of effectively relaxing the people using VR technology.
1) The first step is to put the body at ease. This is essential to this process so a simple massage on the shoulders, back and the nape of the neck can put the subject in a more relaxed mood.
2) Give a small vibration which has some fluctuation pattern. In essence, the subject’s nervous system senses comfort when some kind of vibration is offered from outside of the body. However over the course of the session, the subject would eventually feel no simulation. Therefore, it is necessary to sway the vibration pattern such as one-fifth so that the vibration will always be stimulation.
3) Relax full body by chair reclining. Again it stimulates the parasympathetic nerve activity and it plays an important role in blood pressure control. It has a positive correlation with body reclining angle and it again, necessary for relaxation.
4) Finally, offer the subject a VR headset with a simple virtual world as it is more desirable than the complicated one which is deeply meaningful so that the user can feel relaxed.
5)Finally, offer relaxing music. A clam and quiet music should suffice. BGM is recognised for having a psychological masking effect by its comfortable stimulation so that it is effective to immerse the subject through stereo graphics.
