How Magic Cube works

In simple terms, the Magic Cube works by using the top laser to project the layout of the keyboard. When the finger touches the desktop, the infrared sensor at the bottom senses the blocking of the signal and is captured by the middle sensor. The specific coordinates thus deduce which button the user is pressing. It doesn’t sound particularly complicated, isn’t it? So why have products that have been lacking in practicality for years?
According to the principle of its work, Magic Cube has very high requirements for the surface to be used. We will then try it on the surface of various materials to see how the compatibility of Magic Cube is.
On the ordinary desk surface, the Magic Cube can be used completely. However, the premise is that the light is not strong. If there is a cluster of sunlight or a high-powered desk lamp that illuminates the projected area at this time, the function of the keyboard is completely abolished.
Although the surface of the carpet is relatively uneven, it can still be used normally, but at this time, the laser writing has become very blurred, the recognition is greatly reduced, and the usability is also low.
Then we went outside, we tried to use the Magic Cube on the granite slate of the flower bed. No matter how it was pressed, it didn’t respond. Although the time was around 4 pm, the weather was just cloudy, but the sun was enough to cover up the laser. The projected font.
