Multi-functional laser keyboard, this sounds like a science fiction movie out of the black science and technology products, as if a kind of future language input magic weapon. Instead of taking up real space on the desktop like a traditional keyboard, the keys are projected onto any smooth surface by a laser, instantly transforming it into a non-physical virtual keyboard. The beauty of this principle lies in the fact that as long as there is a flat desktop, the laser keyboard can act like an invisible assistant at your beck and call, allowing you to type, input, and even control devices anywhere, anytime.

The principle of the laser keyboard is not simple. It is a complete keyboard layout precisely drawn on a flat surface by a beam of red light. Hidden inside each laser keyboard is a highly sensitive sensor system that detects every tap of the finger on the “keyboard”. You don't have to press the physical keyboard; just touch your finger to the projected area, and it will be able to sense and “translate” it into the corresponding letters or symbols to be transmitted to your device. This black technology works like a sharp little detective, quickly capturing and recognising the movement of your fingers, making the whole typing experience smooth and responsive.

As a “multi-purpose” laser keyboard, it can do more than just type. Many of the higher-end models can also act as a trackpad and a mouse. That means it's not just a keyboard, it's also a multi-tasker, allowing you to do multiple things in one small device. If you want to swipe the cursor, browse the web, or adjust the volume, just switch to touch mode and use your fingers to do it all with a single stroke. Even some laser keyboards also have Bluetooth audio function, so people have to marvel at this “little guy” is a low-key and all-round “digital Swiss Army knife”. If you open the laser keyboard in the cafe, connected to a cell phone or tablet, the background music slowly rings, and the keyboard projection quietly falls on the desktop - at this moment, you are not only a technology enthusiast but more like a relaxed and comfortable future life player.

However, don't look at the laser keyboard as cool, it also has its own little “temperament”. First of all, it prefers a smooth desktop, such as a glass table, wooden table and so on, to give full play to its power. If you put it on a soft sofa, its sensing effect will be greatly reduced. In addition, because it has no physical buttons, the “feel” is completely different, users may feel a little “unreal” and need to get used to it. After all, we have long been used to the feeling of feedback when we hit the keyboard, while typing on the laser keyboard, you will feel as if your fingers are hitting the air. Therefore, if you are an expert typist, you may need to adjust the rhythm at first to adapt to this almost “suspended” feeling of operation. In addition, because the laser keyboard needs to project light, the power consumption is still quite large. Especially in Bluetooth audio mode, the battery life may make you a bit nervous - you may be typing smoothly, and the keyboard suddenly disappears.

The laser keyboard of the future may become even smarter, with the ability to automatically recognise the user's typing habits so that the more you use it, the faster and more accurately it responds. It may even support in-air gesture operation, like gesture photography, without really touching the desktop, just relying on finger gestures in the air to complete different commands. By that time, our desktop will be completely turned into a highly intelligent operating space, no longer limited to the screen and physical equipment within the framework of the feeling that everything can be used as a keyboard at hand.

Multifunctional laser keyboard is a modern technology to “invisible” direction towards another attempt. Especially in daily life, the laser keyboard is an invisible companion that accompanies you at all times, does not take up much space but is always at your beck and call, whether it is in a coffee shop, on a train, or even at an outdoor picnic, it can provide you with a different kind of typing experience. This small black technology is also shortening the distance between us and the “future workspace” step by step.
