Heads Up Displays are devices that are used for the display of graphics or other information on the user's head. It was first developed in wartime UK when army airmen wore a black skull with white polka dots to warn other aircraft about enemy fires. With time the concept took off and became popular with all branches of the armed services and in particular the navy, who saw the value of being able to clearly display their planes at night. The use of Head Up Display systems became common on ships in the Second World War and then afterwards on trucks, taxis, and on motorbikes. These devices are now as common on vehicles as they are on trucks and motorbikes.
One of the most common uses of a Head Up Display is to keep a helmet, commonly used by members of the armed forces, secured in a place where it can be easily reached. This prevents the head from being damaged in an accident, as well as ensuring that a military person can see what is happening without having to lose his or her head to the light. It is also useful in making it easier for those using motorbikes to see other road users beside them. In fact, some motorbike riders find that using a Head Up Display ensures that they do not bump into other vehicles.
A modern variation of the original is the Helmet Mounted Display. This consists of a bracket attached to the front of the helmet, through which a viewing unit is mounted. Some newer models are equipped with a cable system that allows the user to arm and disarm the display from a distance.
Protective faceplates are mounted over the display for aesthetic reasons. Some designs allow the display to change its display image easily, through the tilting of the tilt mechanism. These types of displays also make it easier to adjust the image so that it appears to be higher or lower than the actual position of the wearer's eyes. Such technology makes these devices ideal for wearing by members of the medical profession.
The Helmet Mounted Displays are available in several different sizes. The most commonly used is the one-inch display, which provides good image reception. The next size down is the two-inch version, which provides slightly better image reception. The next size up is the three-inch version, which is the perfect size for the regular cyclist. Finally, the four-inch version offers the most excellent image quality.
For those who already have a helmet mounted monitor, the best option would be to have the LCD integrated within the helmet. This will allow the cyclist to use the LCD without taking his or her helmet off. This makes the display more convenient. It would also allow the cyclist to use a power source such as a cigarette lighter, for example.
Head Up Display products vary considerably in price. Of course, the more features you add, the higher the cost will be. Therefore, it is essential to understand precisely what you need before you begin shopping. For instance, if your needs are minimal, then there is no need to spend lots of money on added features. On the other hand, if you cycle daily or frequently, you may want to spend more money on getting the most advanced technology.
Head up display technology has come a long way over the years. There are many different companies that make these systems available. It is advisable to read online reviews so that you can get an accurate assessment of the product that you intend to purchase. Make sure to test the system thoroughly before you buy it.
