The laser virtual projection keyboard is very difficult, and no scientist or company has been able to do it yet.

Is it? Now someone has written ** on the Internet, don't let poverty limit.

Imagine it, okay?

Hello, Laser Keyboard is a virtual keyboard that is about the size of a small mobile keyboard (90 x 34 x 24 mm), allowing users to type articles or emails as easily as a normal keyboard. i-Tech Virtual Keyboard uses light projection technology to project a full-size computer keyboard on almost any flat surface. The virtual keyboard is convenient for e-mailing, word processing, and electronic** production when used on pads and smartphones, and users can leave laptops and desks at home.

The applicability technology of the virtual keyboard studies the user's finger movements, decodes and records the keyboard hitting action. Since the virtual keyboard is an image formed by light illumination, it disappears completely when not in use.

Well, to put it simply, it is to use the principle of similar triangle ranging, it actually uses two lasers (a visible laser, a word infrared laser) plus a camera, the visible laser is just projecting the shape of the keyboard, and the word infrared laser and the camera are used to detect the distance between the finger and the word laser, know the distance, of course, know the position of the finger, and then you can determine the key pressed. There is almost no harm to the human body, as long as the power of the laser is properly controlled, and it cannot be directed at the eyes.

Radiation refers to the outward diffusion of energy in the form of electromagnetic waves or particles such as alpha particles, beta particles, etc. All objects in nature, as long as the temperature is above the absolute temperature of zero, constantly transmit heat to the outside in the form of electromagnetic waves and particles, and this way of transmitting energy is called radiation. The same goes for laser keyboards, radiation will definitely be there, but it will never cause any harm to the human body, and you can use it with confidence.

As long as it is an electronic product, there is more or less radiation.

To be sure, it is equivalent to digging some holes in the middle of a layer of plating, and the edges will slowly fall off if you use too much, but the good quality will be used for a longer time (about 1 year).

Anything will fall off under long-term wear and tear, and the water drops will wear through the stone, let alone just a keyboard.

This thing belongs to geek toys.,People who use it basically can't find a few.,Daily office entertainment you still buy a normal keyboard.,This kind of keyboard looks quite hanging.,It's very painful to actually operate.。

The advantage is that you don't need to bring a keyboard, so you can use it anytime, anywhere. The disadvantage is that it is not suitable for long-term use, and is it not tiring to type in the air for a long time? Even if it is projected on the table, doesn't it hurt to press the table with your fingers for a long time?

There is no force feedback, and playing games and typing are not pleasant. It is also easy to touch other keys by mistake. Knocking on the hard surface for a long time, the finger cartilage is easy to wear.

There are a lot of people using it now. With the improvement of the product, the Whistlebird laser projection keyboard has overcome the misoperation, the response speed is very fast, and it is as convenient as typing on the computer, and it also has the function of a mouse. Young students and white-collar workers use it the most.

Foreigners invented laser projection keyboards, mobile phones and iPads can be used, and there is sound when typing!
