Without the keyboard, whether it
is your PC or a laptop it is very difficult to get the access to the various
functions of your system. For instance, while surfing on the internet you have
to enter the website address in the browser however, you can also bookmark your
websites, but most times, you have to enter the URL of the website. Most of us employ
the keyboard to compose emails, visit the different websites, etc. Now you can
also see the laser keyboards in the market. These keyboards are also called as
the virtual computer keyboard.
Nowadays the Smart phones are
also employing the smaller keyboards however; the phones, which are equipped
with relatively smaller keyboards, offer three by four keyboards. In these types
of keyboards, three to four letters are assigned to a single number. However,
there is also one problem with these types of keyboards. The people, having big
fingers, face difficulties in operating their phones with their keyboard. To
eradicate this problem the laser keyboards were designed.
There is also a reason why these
keyboards are called virtual, i.e. Instead of having the physical keyboard, the
virtual keyboard connects the phone, and it projects the beam, which takes the
shape of a keyboard. You can use this keyboard to write on your accessories
whether it is your Smartphone or a notebook.
At the basic of a keyword, we
know that all the keyboards are the input devices. If you are typing anything
on the keyboard, it means you are giving a specific command to your device with
the help of your keyboard. This will allow you to write the word processing
document, you also have the facility to close the program.
These virtual keyboards do not
involve any type of the switches or the mechanical movement. In these virtual
keyboards, the device will emit the QWETRY board on the non-reflecting surface
and it uses red diode laser. It is similar to the laser, which is used at the
rock concerts or any other social events.
However, the simple image of a
virtual computer keyboard will not be helpful. You need something to analyze
the information, which you are typing. Located near the bottom of the device,
the infrared (IR) laser diode shoots out a thin plane of the infrared light,
which is responsible for the writing of the words on the device.
