Description

Elevator button system and method based on projection keyboard and intelligent recognition

technical field

The invention belongs to the technical field of projection keyboards, and in particular relates to an elevator key system and method based on projection keyboards and intelligent identification.

Background technique

As a new input method, the projection keyboard adopts the VKB keyboard technology. The built-in red laser emitter can project the outline of a standard keyboard on any surface, and then track the movement of fingers through infrared technology, and finally complete the acquisition of input information. When using this kind of keyboard, you only need to tap the "keyboard" button projected on the keyboard to complete the same input operation as a normal keyboard. In addition, users can also choose to turn on/off the "key" sound. When the "key" sound is turned on, the projection keyboard can even make a typing sound similar to a mechanical keyboard when typing.

The projection keyboard adopts Bluetooth technology for wireless signal transmission. Currently, it can support WindowsXP or higher operating systems, and can also support smart phones, such as Andriod, WindowsPhone, iOS and other operating systems. It can be connected to desktops, notebooks, and mobile phones through Bluetooth. PDA and other devices allow users to experience the convenience of using a full-size keyboard for input.

Intelligent recognition is one of the core technologies in the direction of image processing. The combination of machine learning and image processing technology is currently the mainstream direction of computer vision. With the development of neural network and deep learning technology, the current intelligent recognition technology is sufficient to identify different characters in video data, including the specific outline of characters, facial recognition and location tracking in the video area.

The use of intelligent recognition technology can identify the characters in the area, the distribution characteristics of the space, the interactive recognition of the characters and the space, and identify the fixed action characteristics of the characters in the video in real time.
