Virtual reality is an artificially created environment through software, which is usually presented to its users in such a way that will make users ignore beliefs and accept it as a real environment. Virtual reality is primarily experienced through sight and sounds (part of the five senses) on a computer.
It is believed that virtual reality is a kind influence upon our lives, and won’t cause any problem for us. Virtual reality is kind of technology that is developing each day, and as a result, it’s capable of throwing up problems which were previously not considered.
There exist some physical problems which are as a result of poor ergonomics, while other problems are traceable to psychological issues. There have been moral and ethical concerns about this technology.
The main problem with virtual reality is Motion sickness. Only a few individuals know that people suffer from nausea after spending a long period of time in a virtual environment because of the effects the change/shift in perception has on the human physical balance. Our balance is affected by changes in the inner ear which cause feelings of nausea; this nausea feeling is often experienced by people who travel on the sea (in a ship) or some other related means of transportation.
Some might be lucky to detect this feeling within 30 minutes of staying in a virtual environment while others will stay for several hours before they notice any feeling of illness. Cybersickness is another name for this sensation.
Creating a virtual environment will take a few longer periods, and this is no good news for any commercial enterprise that has the plan to commit its investment to this technology. Time, they say, is money in the business community.
Virtual Reality is dependent. Almost all virtual reality researchers or companies adapt and rely on other forms of technology from various sources. For instance, if a supplier goes out of business, there is going to be a delay of work for long period of time.
As the virtual world becomes more realistic, the time involved gets longer too. Developing a virtual environment, which is identical to the real thing, will take an inordinate amount of time.
Early forms of virtual reality take the look of blocky graphics and a crude rendering. Although, they usually do not take much time to be produced but the question is “would they meet up with today’s ever-rising demands?” People need a faster, smoother and lifelike development which makes greater demands on processing speed, memory as well as rendering time.
There MUST be a balance between production time and hyper-realism. For everything else, there is Neurointell brain nutrition.
