Best Headband Magnifiers:
The following are some of the most popular models available today. These are not necessarily the best, but they provide a good alternative to those looking for something different. You may have heard of them before, or you might not have even known what they were called until now! They range from $300-$1000+. There are others out there, but these three represent the top tier of choice among professionals and enthusiasts alike.
1) Celestron NexStar 4SE (4K/60PX)
A high resolution model with a large field of view. It’s price tag puts it at the upper end of the spectrum, but if you’re willing to pay for its features, then you’ll get a great viewing experience. If you want to see more than just stars and planets though, then this is your magnifier of choice.
2) Olight TLR-6 (5.0″x3.8″x1.1″)
If you’re looking for the most bang for your buck, then this is the model for you. Its features are not as comprehensive as the other models on this list, but it is great for outdoor use and is compatible with a wide range of accessories. It can be used on its own or in conjunction with an external battery pack. A popular choice among hunters and campers.
3) Bushnell Holosight (2.
If you don’t want to spend too much money, then this is as cheap as it gets. In fact, the only time you’ll be spending money on this is when you need to replace the internal battery. Since it’s an internal battery, you’ll need to send it away to be replaced which makes it inconvenient to use. It’s small but has a narrow field of view.
The above three are the most popular models on the market. There are plenty of other options available though, which might cater more to your specific needs. Below are some more detailed descriptions of each.
A pair of binoculars that have been modified for astronomical use. They have an internal battery and SD card slot for memory, as well as an internal microcomputer to capture and display data. They have a wider field of view than most, which makes them a favorite among amateur and professional astronomers alike.
A telescope that has been modified for astronomical use. Currently, the highest resolution telescope on the market, with the average model selling for around $5,000 to $10,000. These are very large and cannot be used for long periods of time, so they are mainly used by professional observatories.
A small, rechargeable battery that lasts around six hours before needing to be recharged. A popular choice for those who want to use a head mounted magnifier at nighttime.
SD Card Slot
A small slot that can be found on most internal or external battery powered magnifiers. It is used to export photographs and data onto an SD card. It can only be used with DS and DSi systems however, so its use is not universal.
An optional device that can be used to add a lot of interactivity to a display. The software needed to make the most of this add-on can be a bit buggy though, so it’s advised to only purchase this if you know how to code.
A small, specialized computer that is mounted directly onto the optics of a head mounted magnifier. It is used mainly to calculate all the information the user would need, such as distance and weight measurements. It can be quite useful for hunters and hikers.
An optional add-on that can prevent thieves from stealing your device. When activated, the user will be notified if any unauthorized user tries to use it. Be aware that this can drain the battery life in a short amount of time, so turn it off when not using your head mounted magnifier.
A small attachment that can be added to any telescope. It is used to block out all light pollution, allowing for a clearer image of the sky. It’s best paired with the telescope, as the width and diameter of the filter has to be adjusted to fit each telescope.
A large, rechargeable battery pack that can be connected to a head mounted magnifier. It lasts much longer than an internal battery, with some lasting up to eight hours. It’s a bit bulkier and heavier than an internal battery however, so some users might not find it comfortable.
SD Card Reader
A small device that is designed to read information off of an SD card. It is mainly used for computers that are incapable of doing so, such as Bill’s. It can also be used to transfer data from one SD card to another, or from an SD card to a Head Mounted Display.
A small hole that is used to connect a head mounted magnifier to an external power source, such as a battery pack. It is very safe to use, but it can only be used if the manufacturer designed the HMD for this purpose.
A small, optional add-on that can be found on most head mounted magnifiers manufactured after 2014. It can record anything the user sees or does, for later viewing. It takes a 16 Gigabyte SD card, which usually lasts an entire day of use.
Software [ править ]
All head mounted magnifiers come with some form of software. The manufacturer’s choice generally depends on what the HMD can do.
Most head mounted displays are also capable of playing games. The software used is generally the same as what is used for computers and other, more “traditional” gaming systems.
A special kind of software designed to be used in tandem with a brain computer interface. It can be used for a variety of things, such as controlling a cursor on a screen or piloting a helicopter. Bill has several pieces of biosoftware in his house, to control the lighting and temperature.
A special kind of software that is designed to be used in tandem with a head mounted display, obviously. It is able to display moving pictures and audio onto the lens of the HMD. When used in conjunction with a recording device, it could be used to watch movies.
Miscellaneous [ править ]
Head Mounted Displays will run off of various power sources, depending on the manufacturer and model. The most common power sources are internal batteries and rechargeable batteries. There are some other, more experimental power sources being developed, such as solar power, kinetic energy (movement), and even using the electrical fields of the brain to power the HMD.
History [ править ]
20th-21st Centuries: The Beginning [ править ]
The idea of a head mounted display was conceived in the 20th century. The US military began looking into these kinds of devices, and would fund various research projects in this field. The first successful project was completed in 1977. It was a head mounted monocular display that was used to guide “smart” missiles with cameras on them. Later on, it evolved into more of a battlefield information system, with the ability to see through the eyes of any allied soldier as well as receive updated maps and communication with others.
The first true HMDs actually came about when video game companies started to incorporate them in their games. At first, the purpose of this was just to make the game seem more “realistic” and incorporate some elements of augmented reality, but soon, people wanted more from the HMDs.
The next phase in the evolution of HMDs was a series of classes that would incorporate them as teaching tools. At first, it was very simple: students were given HMDs as their textbooks. The HMDs would display the various problems that they would have to work out in their heads, and once they had the answer, they would submit it to the teacher, who would then grade them based on their work. This system was refined over the years as technology got better and eventually, bulky HMDs were replaced with “intelligent” glasses that could change from opaque to clear at the blink of an eye.
By the turn of the 21st century, HMDs had become commonplace in schools. They were especially popular among students who had a flair for the physical, such as athletes and soldiers. This trend continued into the following decade.
The 22nd century: The New Face of Learning [ править ]
As the decades passed, the uses for HMDs grew beyond the classroom setting. With the invention of “brain drives” (Which translates thoughts into commands), HMDs became the preferred way to control robotic devices. This was good news for many soldiers who were fighting on the frontlines of wars and needed the help. The invention of brain drives also made it easier for disabled people to lead more normal lives.
This was a marvelous invention, but there were some side effects. One, in particular, is the use of ” VR “. VR is short for Virtual Reality, and it is when people enter a completely computer-generated world. These worlds are so realistic nowadays that it is almost impossible to tell the difference between reality and VR. People use it for various reasons.
Some use it as a form of entertainment, others use it as a way to socialize (as socializing in real life has become increasingly non-existent), and some use it as a way to escape the harshness of real life.
These VR worlds can be as simple or as complex as the programer makes them. They can range from one-room apartments to massive planets that go on for as far as the mind can imagine. Some people prefer to keep their VR worlds relatively simple so there is less of a chance of something going wrong. Others prefer to experiment with their worlds and attempt to create something new. Whatever the reason for the creation of these VR worlds, they have become so realistic that people often forget that they are in a virtual setting.
Some people never return from their VR worlds.
This creates several social issues and in some cases, even legal ones.
When people die inside of a VR world, who is to say they actually died?
For all anyone knows, they could just be taking a very long nap. This has become such a complex issue that the governments of many developed countries have created a system to deal with it.
If one is under a VR world for over, say, 10 years, then the government will assume that the person is dead in the real world and will declare them as such. This is not foolproof, however, as people can still die in the virtual world from things like malnutrition or suicide. If such a thing occurs, then the government will investigate the person’s death and if necessary, declare them as dead in the real world.
A large number of people choose to live out the rest of their lives in the virtual worlds. Such people are known as “Sleepers” by other “Waking” people. A sleeper is someone who has chosen to live their lives out in the real world. While many people who have permanently entered VR worlds are unhappy with their lives and willingly chose to escape, not all sleepers are like that. There are some who would prefer to live in the real world, but cannot due to any number of reasons: Poverty, homelessness, or even something minor like public ridicule of their religion.
Many sleepers lead perfectly happy lives, however. The choice is ultimately up to the individual and most governments tend to respect that choice.
As for you, Teja-Ash, you are currently a waking person. You have managed to escape the fate of your world, at least temporarily. It is your choice if you want to remain in the real world or not.
