Developing technologies are finding their way into our lives on daily basis. In order to get a full grasp on these technologies, users often have to invest in accessories to support them. Smart TV owners are aware of the fact that they are often required to have a wireless keyboard in order to take advantage of everything that this device has to offer. It is important to note that the wireless keyboard is not required to operate a Smart TV, but it certainly makes things much easier and more enjoyable. Corded models are an option too, but the cords are often too short, limiting the user’s movement.

Types of Wireless Keyboards
Several factors need to be considered when buying a wireless keyboard. There are numerous types available on the market, but you will most likely end up getting one of the three most popular: Virtual laser keyboard, Bluetooth keyboard or radio frequency keyboard. Naturally, each of these has its advantages and disadvantages.
Bluetooth Wireless Keyboard
Bluetooth wireless keyboards have no competition when it comes to responsiveness and range. You can use them with almost any device that supports Bluetooth technology while staying completely mobile since the keyboard has no line of sight issues. While most of these keyboards will be compatible with your TV, it’s best to make sure that you are getting the one that is supported. Like any device, these have some disadvantages attached to them as well. First and foremost, they are more expensive than any other type of wireless keyboard out there, and they can get quite pricey. If money is not a major deciding factor for you, then this might be the best choice.
Virtual Laser Keyboard
Virtual laser keyboards are devices that operate on a concept of enjoying the hardware without having the actual hardware in front of you. Virtual laser keyboard is a great piece of technology that doesn’t have any keys, cables or switches involved. This device directly projects a keyboard onto a flat surface using a diode laser. The laser beam travels through a DOE (diffractive optical element), and it projects the image onto a surface. This means that you do not actually have a keyboard in front of you. What you have is a device which creates a keyboard for you, so to speak. This same device processes the position of your fingers as you type on the keyboard, and sends the processed information to the computer. Disadvantage of this device is that you need a completely flat and non reflective surface in order to operate it. Another disadvantage might be the lack of responsiveness of pressing a key. Until you get used to it, expect to make a lot of mistakes.
Radio Frequency Keyboard
Radio frequency (RF) keyboard is another popular type that you can use with your Smart TV. They rely on a transceiver which you will have to plug into the USB port on the Smart TV. These keyboards have a very limited range, making them less popular for people who sit far away from their Smart TV. Another issue with radio frequency keyboards is that they operate on a 2.4 Ghz frequency. This frequency is shared by many devices, so it might cause a lot of interference, ultimately making the keyboard unresponsive.
