Virtual reality is referred as immersive multimedia or computer-simulated life. It imitates an environment, which can be a place in the real world or a made-up world, and lets the user interact with it. In a virtual reality, it artificially creates sensory experiences which include sight, hearing, touch, smell and taste. The simulated environment is used to create a life-like experience that can be used in medical, gaming and military applications. The most updated virtual reality environments are displayed either on a computer screen or with special stereoscopic displays, with additional sensory information that focus on real sound through speakers and headphones. In more advanced equipment, they use 'haptic', a system used for tactile information that recreates the sense of touch by applying forces, vibrations or motions by the user. With the use of multimodal devices, like wired glove and omnidirectional treadmills, these provide more interaction and make it feel like a real world environment.
There is a new Portland startup that is called as "Wild". This simulation combines reality with the virtual world. It is a platform that maps physical objects and people into virtual reality. People will be able to experience immersive multi-sensory, where they can see, move and feel the story. The best thing about it is there are no controllers, vests, gloves or wire; people will just have to wear a wireless headset.
With the continuous development of technology, the demand for employees with virtual experience increases. Companies are hiring more people to develop devices and applications; to infiltrate the market; and gain customer acceptance. Currently there are over 200 companies that are advertising for candidates with virtual reality knowledge. In terms of filling the position for the virtual reality jobs, it may be somewhat difficult due to the limited opportunity that exposes professionals in this job. This area is still new and just starting to grow.
