Description
Consumers have an insatiable desire to improve their convenience, security, and user experience, and we have developed a high-performance product for this purpose, which is our 2.8 Inch Smart Home HMI! It covers all kinds of input methods and computer vision functions from voice to gesture to video, and is applicable to all kinds of applications from sales terminals to smart homes. In addition, it can not only understand the direct command, but also infer the user's intention according to the user's usage habits, bringing people the ultimate smooth experience.
Features
Considering the specific use case requirements, development options, and smart devices, the 2.8 Inch Smart Home HMI has introduced a new level of automation to enhance cognitive intelligence and environmental computing capabilities and provide people with a more intelligent user experience. At the same time, it is equipped with a high-quality programmable touchscreen display and a powerful editor. You can easily add audio, video, and animation resources to the project, and control the state and cycle by editing the resource properties, thus creating a vivid and intuitive interface.
