Foreword:
"Detective Chinatown 2" is indeed a good Spring Festival movie worth watching, with comedy and brain-burning, as well as rich Chinese characteristics. And the black technology in the film is so grounded, you and I can have it, think about it, maybe you can become a detective!
In the video, there is a detective who relies on technology to solve crimes, but she actually looks more like a hacker. In addition to the powerful implantation of the Xiaomi notebook, the movie is certainly eye-catching, and it should be the assembled mini notebook. Including a pocket-sized host, a laser projection keyboard, and a huge projection display.
Although it looks futuristic, these technology products have actually appeared in our daily lives. Let me talk about this mini computer host first. At present, there are many small computer hosts on the market. Although it is difficult to achieve the size as small as in movies, they are still much smaller than ordinary computers.
Laser projection keyboards have also been more common, and the keyboard is projected onto the desktop through projection. Only need to type on the virtual desktop keyboard to realize the function.

1. Product overview:
The laser projection keyboard is a keyboard connected to the main device via Bluetooth HID, suitable for desktop computers, tablet computers, smart phones, game consoles and other devices. As a new input device, the projection keyboard uses a built-in infrared laser transmitter to project a standard keyboard outline on the working plane, click the pattern with a finger, and determine the click position through optical recognition to complete information input. The laser projection keyboard has no physical buttons and is connected to the main device via Bluetooth. It is small in size and easy to carry, which can adapt to most working environments.
2. Working principle:
The keyboard projector of the laser projection keyboard will project the outline of the keyboard on the working plane. Its bottom end emits infrared light to detect objects such as fingers. When an object passes through the infrared light irradiation area, the sensor will detect the infrared light reflected by the object. Perform keyboard operations by analyzing the position and movement of objects.
