Computer

You may have come across the phrase either in gaming forums of in science fiction, but exactly what is meant by virtual reality, what is it, and does it present us with any possible benefits or advantages in the future?

This phrase can be answered by either simply looking at the technology currently used, and understanding the basics of how it works, and what it tries to achieve. The more complex way of looking at this concept is by firstly asking what we understand by the word reality, before we try understanding the idea of an alternate, virtual version of reality.

Basically, if we understand the idea of reality to be the sum of all of the sensory inputs our brain receives, virtual reality is the use of technology to replace as many of those sensory inputs as possible with computer generated ones, to fool the brain into believing in a world which is false, and which only exists within the brain of the computer.

The most common form of virtual reality is one where the user wears a visor which wraps entirely round their normal field of vision. The computer then projects or displays a visual three dimensional world onto the inside f this visor, entirely replacing what the user would normally see with a computer generated view. The clever part of this is that the visor has a number of motion sensors built in to it, so that if the user turns their head, tilts their head, or moves their body entirely, the display inside the projector will move to match the user's movement, creating the illusion of the user actually moving around within this three dimensional world of the computer's.

Taking this idea further, the world may contain a number of objects, such as furniture, doors, objects that can be picked up and examined. By wearing special gloves which have a whole range of sensors built in to them, the computer can track the position, movement and actions of the user's hands, and work out whether they would be touching anything, and if so, how the objects would react. Would they be being picked up, turned, knocked over and so forth?

By adding audio as well, the user can be very immersed within this world, and with advancing technologies making greater and more realistic computer generated scenes, the user can very easily start to believe in this virtual world, or reality.

One way in which this technology is an exciting area for development is within computer and video games, and already we are starting to see early developments of this with basic visors, and hand controls which are motion sensitive. Eventually we may well all find ourselves entering an alternative reality in which to play our games, which would make chase scenes, fights and cliff top adventures even more breath taking!

A motorcycle insurance quote is based on the type of insurance coverage a motorcyclist requires. The most basic element of an insurance quote for motorbikes is the liability coverage which includes coverage for bodily injury per person, bodily injury per accident and property damage coverage per accident. It is always a good idea to obtain more extensive liability insurance than what the law requires because drivers can sue other drivers who injure them in accidents and minimum liability insurance does not cover this risk.

If a rider causes an accident, collision insurance will cover the cost of motorcycle repair. Collision coverage is the most expensive component of a motorcycle insurance quote. A higher deductible can result to a lower premium. The cost of replacing a motorcycle or repairing damages with materials of similar kind and quality, without removing depreciation, is the replacement cost. Depreciation is the estimated value of the vehicle when wear and tear is taken into account. Insurance companies would declare a motorcycle a total loss when the repair costs exceed a given percentage of the motorcycle's worth.

Comprehensive coverage, on the other hand, pays for motorcycle damages that are not due to an accident. This covers anywhere from damages caused by theft, fire, vandalism, disasters to hitting an animal on the road. It is wise to check a motorcycle's book value as insurance companies do not normally pay more than this particular value.

Another part of the insurance package for motorcycles is the medical payments that cover the medical expenses incurred by the rider and his passenger, if any. The expenses can come from accidents while riding one's own motorcycle or someone else's with permission. It also covers injuries incurred as pedestrians. Expanded forms of this coverage include personal injury protection and broader no-fault coverage, which may pay for lost income and child care.

Meanwhile, coverage for uninsured and underinsured motorists pays for injuries incurred by a rider if he figures in an accident where the other party or parties have no insurance. Some companies even provide coverage for property damage. Other supplemental coverage products are also offered by companies either as part of the master policy or as separate premium items. These could include rental reimbursement, towing and labor costs and gap coverage for a new motorcycle. The last item pays for the difference in the actual cash value of the insured motorcycle and the amount left on its financing if it was declared a total loss in an accident.

Most consumers would admit to not fully understanding a motorcycle insurance quote that is provided for them when purchasing insurance for their motorcycle. People tend to focus on the bottom line figure giving little or not attention to how this figure was arrived at. It would be wise to gain an understanding of the basic features of a motorcycle insurance policy if only to realize that the money paid for the premium is indeed well spent.
