Literature Review Virtual Reality
In most instances, the organizations are using virtual reality technology to gain competitive advantage over other organizations in the industry. Most organizations have realized the magic behind this technology, and they are persistently applying and integrating it in their operations. Because of the enormous benefits resulting from virtual reality, over the past decade, it has become one of the most studied technologies in the world. Undoubtedly, VR has transformed the world into an amazing place (McGauley). The researchers have studied different aspects related to virtual technology including its meaning, history, applications, advantages, disadvantages, and several other aspects. The response can be found in Jang et al. work. According to the author, virtual reality enables students to study complex issues in an easy way, which they can be able to visualize.
It facilitates communication between the teacher and students, since a teacher explains different things to student in a simple way. For example, a tutor can explain sophisticated anatomical structures in 3-D virtual environment, thus making the student to understand easily. Merians et al. (6) perceives virtual reality as a form of artificial environment that is normally experienced via sensory stimuli offered by a computer. With virtual reality technology, it is possible to predict what will happen in the future. This characteristic makes virtual reality technology a very significant application in business operations. This characteristic helps organizations to avoid risks by taking the most appropriate decisions that are viable. For example, Morton Heilig idea of stereoscopic display enclosure played a significant role in laying foundation for the virtual reality (History of Virtual Reality).
Again, Post World War II led to significant improvement in virtual reality since the technology was helpful in the war. During this time around 1980’s started realizing the benefits of this technology and it started spreading swiftly. A Head-mounted Display, an invention made by Ivan Sutherland’s, marked a great milestone in advancement and development of virtual reality. At the start, virtual reality was just utilized in two major industries including medical and military industry (Schroeder 963). With the current development in VR technology, it is plainly evident that more VR products will continue to be developed in the future. There are still many unmet consumer demands that can be fulfilled by use of virtual reality. Types of Virtual Reality There are various types of VR categorized based on mode by which the VR is interfaced to the user.
The most common types of VR include immersive systems, video mapping, and lastly, telepresence (Larry). Video mapping is best illustrated in the highly prolific famous computer game called DOOM. In virtual world, telepresence has mostly been applied in firefighting, medicine, space exploration, and in robotics. Doctors utilize very small gadgets fixed on capable to perform surgical operation on patients without making significant incisions in the patients. A camera is fitted at one end of the equipment. An extensive research is still being performed in an effort to advance this technology. Presently, robots integrated with telepresence systems have extensively been utilized in volcanic exploration and in exploring deep see. Robotics As prior stated, the development of telerobot has led to extensive research since the researchers are able to explore deep see and space.
The development of VR in robotics has simplified the process controlling and manipulating the robotic structures as compared to conventional method that required use of complex programming (Vetter and Schwan 128-132). Through VR, it is possible to control the robot directly by the use of VR devices. In addition, VR is also utilized in machinery maintenance operations. In an ordinary world, a technician is forced to learn how to utilize, repair, and maintain new machinery. For example, Boeing researchers are persistently working towards developing VR display systems for replacing enormous work frames utilized in making wiring harness for the airplanes. The use of experimental systems allows the maintenance and repair technicians to be guided by VR displays, which indicates routing of cables on the generic frames that are utilized for all connections and attachments.
Dentist Operations Dentists currently utilize VR in removing tooth from the patient. Traditionally, the process of removing teeth by a dentist was very scarily. Consequently, only a few people will go to visit the dentists when they had teeth complications. According to the researcher, further research needs to be done regarding how employees themselves can use VR to enhance their collaboration skills. This will help in forming effective team in organizations. Data and architectural visualization Previously, numerous organizations had complexity in managing and organization various data because of its enormous amount. Managing megabytes and gigabytes is truly not an easy task. In an effort to make complete usage of data received by a company, the organizations developed special visualization techniques. Using VR in manufacturing process is associated with the significant benefits of saving time and reducing cost.
Collaborative Virtual Environment In the current world there are numerous technological advancements, which purpose involves supporting cooperative interaction in organizations. Collaborative environment extends the idea of VR by incorporating networking concept (Rosenblum 13-17). The concept of integrating VR with network enables different users from diverse parts of the globe to communicate in shared VR environment. The utilization of communication technology aids in overcoming geographical barriers of collaborators (Rosenblum 13-17). In this game, the researchers were able to separate interactive players 60 km apart from one another. Moreover, the players were completely immersed into VR environment by data gloves and mounded displays (Mahoney). A general purpose server network system was then utilized for manipulating the shared virtual environment through the Asynchronous Transfer Mode network system (Mahoney).
The avatars were utilized for supporting the body deformation during the process of motion. Moreover, in this game, the researchers also represented autonomous virtual actors, which were part of the simulation. Presently, the VR technology is extensively applied in gaming and in medicine. There is need to extend the scope of its applications to other things such as tourism, entertainment, education, and several other fields (Onyesolu). Not to leave behind, VR also experiences a challenge of bringing real element. VR applications should completely dominate the users mind and thinking, making them believes that what they hear or see is real. Attaining this goal is not an easy task. Conclusion The literature review conducted has show significant details about virtual reality including its history, applications, types of virtual reality, and several other aspects related to virtual reality.
However, some gaps have been identified in the current researches that need to be dealt with. Firstly, very little details have been reported regarding how virtual reality is significant in the field of disability. Therefore, further research is required regarding how VR systems can aid people with various disabilities. Secondly, the current literature review has shown that VR systems are very complex. Further research needs to be performed regarding how collaborative virtual environment can be utilized in various fields including engineering, medicine, architecture, and several other fields.
