Virtual Keyboard with Laser Projection: Discover This Technology.

Announcement

Before talking about the virtual keyboard with laser projection, it is worth highlighting that most people use a computer daily. Even those who don't use it daily have undoubtedly used it at some point in their lives. This could be for sending an email, writing texts and documents or even for online games. 

Therefore, if there were no keyboards, communication could certainly be limited between distant friends and family. Well, the tool simplifies people’s lives a lot these days. With this, we also have access to smartphones that have digital keyboards to make it easier to send an email, text message and other possibilities. 

However, on cell phones, these keyboards can be extremely small and therefore some people may have difficulty using them. So, to help with this issue, several manufacturers started to invent portable devices. Therefore, instead of the user just using the phone's keyboard, they can use a virtual keyboard with laser projection. See more details below.

How Does This Keyboard Model Work?

Now, to better understand how this virtual keyboard with laser projection works, know that it needs a flat surface to work. Furthermore, there is no involvement of switches or moving mechanics. To do this, using a QWERTY keyboard, the device projects itself onto a completely flat, reflection-free surface, using a red diode laser. 

However, it's not enough to just reflect the image of a keyboard somewhere, of course. In reality, you need to use something that can read the information you type. Therefore, to pass this information there is an infrared laser on the bottom side of the device. Then, a thin plane parallel to the surface is released with infrared light located just millimeters from the keyboard image.

Therefore, when you start typing, your fingers will pass through some areas of this infrared light. This way, a complementary metal oxide semiconductor indicates where your finger is on the keyboard area. Then, the special sensor chip analyzes the ideal location of the intended keystroke. Subsequently, the device sends all the information to command the computer.

Virtual Keyboard with Laser Projection in Practice.

Typically, almost all devices stand on a rectangular surface. Furthermore, when it is turned on, it is possible for the keyboard to connect to any device via USB cable. Or generally, the connection via Bluetooth, wireless technology, is also used. Both options allow you to send document information via the virtual laser keyboard. 

However, although this technology brings many benefits and facilities, it is necessary to pay attention to some details. Because, although it is possible to take it anywhere, the way to use it is not that simple. For example, you can't just take the virtual keyboard out of your bag and place it on your lap to start typing.

Therefore, for your keyboard to work correctly, you need to follow the correct way of using it. Therefore, for this to happen you must only use smooth and flat surfaces. Furthermore, ideally surfaces should be non-reflective and opaque. So, you need to follow exactly how to use projection and typing.

Final considerations.

In short, basically all types of keyboards, whether physical or virtual, function as input devices. This way, every time you type a series of keys, you will be sending a message to your keyboard to send a command to your computer. So this will allow you to be able to write in a document with word processing.

However, the virtual keyboard with laser projection can be an ideal solution for smartphone users. Therefore, they can write longer messages on a full-size keyboard. Therefore, this technology can provide a full-size keyboard anywhere, without the weight and hassle of a larger computer or keyboard. 

However, more technological keyboards, such as the one we present in this article, need an absolutely flat surface. In this way, we can say that technology is increasingly helping us and making our daily tasks easier.
