Best Virtual Keyboards 2017

What if you don’t need a physical keyboard connected to the computer? Imagine that you are sitting in a cafe, on the table in the office, and even at the table in the house with the ability to write as you would normally on the laptop without having to use like any other keyboard. It is a masterpiece of magic? Not really. Whether it is practical, convenient and adequately technological maniac in many ways?

Regardless of whether you prefer to travel light, and the sound of the keys makes wzdrygasz, the virtual keyboard can be an innovative addition to your Arsenal of technology. Why? Zagłębmy little that actually makes this device.

Also called a virtual keyboard, an optical or an on-screen keyboard , virtual keyboard is a unique form of computer input device in which the digital keyboard is displayed on virtually any flat surface using a red laser diode . This laser shines glare optical element , a small picture of the keyboard in the QWERTY style. Together with the special lenses, optical DOU extends the keyboard image, usable size, which is ultimately displayed on a flat surface. However, the keyboard itself is not enough.

The device still requires the interpretation of information at the time of writing. Laser diode the infrared port located on the bottom side of the input device, displays a thin plane of infrared light is invisible and runs parallel to the proposed surface of the letter. When you record on this surface of the fingers pass through certain areas on this plane. And get a metal-oxide-semiconductor photo on the position of the fingers on the keyboard, and the integrated sensor called a Virtual Interface to create a Core analyzes the location of the proposed keystroke. At the end of the device sends this data back to the computer to interpret the command.

Virtual keyboard works just like a regular keyboard, which means that still is an input device that accepts and interpretirovat command (or keystroke) and displays them appropriately on your computer or mobile device. Its main advantage compared to conventional keyboards is its portability.

Most virtual devices, buttons are small and lightweight, often not more than a pack of chewing gum. This means that they can fit in almost any bag or pocket. The virtual keyboard can connect to your laptop, tablet, PDA or smartphone via USB cable or Bluetooth technology . When connected, the virtual keyboard can transmit commands / data keys back to the text editor or any other active window on your mobile device / computer.

The projection of the right ideas
It should be borne in mind that the virtual keyboard requires a flat, nieodblaskowej and nieprzejrzystej surface on which to operate. However, the use of it in some places (e.g., bus, train or car), is not the most user-friendly experience for this device. But this should not be discouraged to invest in one to make your job easier.

Speed is an important factor when making a choice. Some of the virtual keyboard may detect up to 350 or 400 characters per minute, so even if you are one of the fastest typists, you don’t have to worry about your ability of the unit of prosperity. In the same note it is important the evaporation rate, because you don’t want to spend time on installing additional drivers. Many virtual keyboards do not require drivers.

If you are like many computer enthusiasts, you know how Mac and PC, and therefore it is useful to find a virtual keyboard, which is widely compatible with various operating systems.

Built-in range of adjustable parameters of the brightness control is very useful if you plan to use it during the day. Of course, you’ll need a simple adjustment at night, to ensure that the projected light is bright enough to see them.

The battery life is another biggie. A lot of virtual keyboard features a rechargeable lithium-polymer battery that extends the operating time of 2-3 hours and allows you to charge your devices virtually anywhere.

Innovation: past and future
Optical virtual keyboard was originally designed, developed and patented in 1992. Engineers IBM .

In 2002, Run under Canesta created the first on-screen keyboard, which uses proprietary technology e-perception, which is cheap, jednoukładową the image processing technology used to create three-dimensional images of the immediate environment and objects in real-time. Keyboard Canesta projection was the first application of this technology.

From there, this type of technology perception / recognition can be used in the future to create additional functions of recognition of the spatial / object-oriented, including such things as door knobs, which recognize the hands of homeowners or home security systems that are smart enough to distinguish between dubious movement from permitted actions.

Along with the latest patent Apple has been testing since 2006 of water to develop its own virtual keyboard which will make sure that the technology is very flexible, taking into account the innovation of the iPhone and ipad among other products.
