The evolution of computer keyboard

Today’s computers are quickly leaving yesterday. If you look closely into the features they possess today, you can realize it that they are far beyond from the previous computer models. Every day, the computer technology is making computing experience more intriguing. Even the accessories (the most valuable assets of a computer) feature new and enhanced technology that is giving better computing experience today.

Over the years, keyboard remains the primary input device for many important tasks like emails, word processing, web searches, browsing internet etc. But since, adapted from the typewriter, the computer keyboard has gone through many changes over the years and today features laser technology to enhance the typing experience even much better.

Virtual laser keyboard –

This technology is more like a future equipment. Still today people do not be able to believe that this technology today exists, which truly is capable of converting any flat surface into a computer keyboard. Well, yes, a virtual laser keyboard can do so!

By using many sophisticated sensors and laser module, the device projects an image of a QWERTY keyboard on the flat surface and allows a user to press the alphabet letters in order to record subsequent keystrokes.

Well, literally speaking, the device has many advantages on that feature. For instance – a user can easily carry it in his pocket and can use it with any computer he wants to. Moreover, he can use it with his iPhone and iPad or any other smartphones by connecting it via Bluetooth.

Basically the way people are using their computer or smartphones or tablets, this virtual laser keyboard can be a great advantage toward their personal experience. For instance – people with bigger fingers may find this keyboard useful, because the existing keyboard within the smaprtphones is too small that people usually find difficulties typing the letters. So in that context, a virtual laser keyboard will certainly be handy to them. Well, not only that the device can give them an amazing typing experience that they would have never experienced.

A virtual laser keyboard is the new revolution to the computer keyboard and people those who are already using it are very much satisfied with the experience and I am sure, you will too once you start using it personally.

Well, if you really want to experience this new technology, then make a purchase to this online! You can find many online stores selling this product!

Common Laser Measuring tools for Engineers

Engineers require precise tools in order to design infrastructures. Even ancients were used to rely on this precision. As some of the fundamental architectural tools have evolved over the centuries, infrastructures building are not possible without it.

In the advanced manufacturing, logistics and engineering industries, Engineers are using a variety of tools i.e. design software, drawings, and a few laser diode mechanism aided measuring tools these days.

Some of the laser-measuring-tools for engineers are -

Laser Distance measuring Device – This device is used to determine the distance between two points. Despite of several measuring tools, this laser tool is very easy to use and is more accurate.

Laser levels – This device is used to transfer reference points in awkward positions to display the unit of measure of your choice.

Laser land surveying equipment – This tool is very convenient for taking measurements of lands. This tool provides architects sufficient initial measurements without making any delay.

Well, these are the tools that are being utilized by many professional engineers today!

Benefit of using Laser Pointer in Classrooms

Gone are the days when teachers were using traditional accessories in schools. The New Laser Diode Technology has changed the mode of teaching today. Despite of using the wooden teaching sticks, teachers these days are using laser pointers to pointing out the context over the whiteboard.

 

The best advantage of using laser pointer is - you do not need to stand in a particular place (close to the white board) to denote something on the screen. You can move to anywhere in the classroom and can specify your points and subsequently can draw student’s attention to the whiteboard with the help of a laser pointer.

The pointers that are being used by many teachers in schools and professionals while giving presentations are nothing but the devices that produce radiations. In other world you can say, these devices emit lights (i.e. red light) that point straight, which is what helps teachers to use that device to pointing out any particular context on the screen from anywhere in the classroom without standing at the same place from starting to end during the period.
