In modern times a technological development has achieved an unprecedented pace, thereby, making advanced technologies more affordable for ordinary people. It particularly concerns devices of an augmented and virtual reality. Despite the fact that both of these technologies have somewhat similar approaches, their functional differences are essential. For instance, the Facebooks Oculus virtual headset is predominantly designed to simulate imaginary environments for training and create entertaining realities. At the same time, an allegedly similar Google Glass does not have such entertaining and training possibilities. Its purpose implies to enhance an actual reality by projecting an additional content on glasses and match it with real-life objects. By conducting a more thorough comparison of features of augmented and virtual realities, the most effective application of both technologies can be determined, what will ultimately contribute to their proper development.
A comparison of this sort is very common in medicine and social science. To evaluate the effects of some intervention, program, or treatment, a group of subjects is divided into two groups. The group receiving the treatment to be evaluated is referred to as the treatment group, while those who do not are referred to as the control or comparison group. In this example, mothers who are part of the prenatal care program to reduce the likelihood of low birthweight is the treatment group, with a control group comprised of women who do not take part in the program.
