Laptops become an essential need in offices. Some people need to carry a laptop everywhere. But sometimes it becomes a hassle to carry a laptop while traveling. As it occupies space and needs care.
We can use smartphones instead of a laptop. As smartphones are light in weight and can be used anywhere, but selections and typing are so messy on the small screen of the mobile phone. Laser keyboard could solve this problem.
What is a laser keyboard?
It works with the projection technology. A keyboard image is projected on a flat surface. When the user touches the image of the key on the surface, the system records a corresponding keystroke. Some of them connected with Bluetooth devices and others will connect with devices such as the latest mobile, tablets, mini pc with operating systems like IOS, Android, and Windows.
How it works?
It uses sensors or cameras to pick the data from the user. It picks the movement of the user’s fingers and coordinates the data into keystrokes. To make a keystroke user has to touch the image of the key on the virtual keyboard.
Laser keyboard uses a red diode as laser and projects a full-size keyboard. The size of the projected keyboard is usually 295 mm X 95 mm. And the projector makes the virtual image of the keyboard at a distance of 60 mm.
Why use a virtual laser keyboard?
Laser keyboards provide high portability. It is difficult to input data on mobile phones because of the size of its keys. Some users get used to it but it is still a mess. On the other hand, laser keyboard provides full-keyboard virtually that provide a comfortable environment for input your data.
Laser keyboard fits in every mindset. It is found attractive to many people because of its working. It has an attention-grabbing functionality. Some of the keyboards provide the image in the air to allow control without any flat surface.
Unlike any other hardware, laser keyboards do not require any maintenance. As the virtual keyboard has no moving parts… and it is not attached to any devices with wires. The projector of the laser keyboard requires some maintenance, although it is easy to maintain the laser keyboard.
Everything has two expects. As there are many advantages of laser keyboard as well as there are some disadvantages.
Need correct angle:
Laser keyboards that connected with mobile and tablets have an inorganic issue, that they need to be at a perfect angle to operate the keyboard. Laser keyboard is projected on a flat surface as if the surface is not flat the input could be disturb.
The laser keyboard works with a flat surface. It means users need to find a flat surface to operate this keyboard. Sometimes it becomes difficult to find that kind of environment. But the users are okay with these disadvantages.
In a nutshell laser keyboard is a revolutionary invention for data input. It will make you capable of using a full-keyboard anywhere at any time. Still, scientists are finding ways to make this technology more efficient.
