This is an ultra-high-definition decoding network keyboard, which is applicable to the safe city multi scene (such as public security systems, transportation systems, shopping malls, etc.). Designers designed it from the perspective of the user experience and carried out tests of human computer interaction through the simulation of a variety of scenarios. It broke with the traditional thick network keyboard form and applies the appearance of a split-body design, so that the shape of the curve fully fits the arm. The new product has a strong technical support. It also achieves a higher versatility and comfort through the innovation of hardware and software.
