Problems solved by technology

[0003] At present, there are already a batch of human-computer interaction solutions and equipment based on gesture recognition on the market. However, such solutions generally only recognize static gestures, and most require special equipment, and the application scenarios are relatively limited.
Take the gesture operation of Microsoft’s Xbox One console as an example. Its gesture interaction solution not only needs to be equipped with a dedicated Kinect depth camera, but basically can only recognize body movements. The recognition rate of gestures is low, which cannot meet the daily needs of users.
On the other hand, due to the limitation of the computing power of embedded devices in the home scene, existing solutions cannot use convolutional neural networks with the best performance in the industry, such as residual networks, but can only use support vector machines in traditional machine learning algorithms. Even simple template matching methods are used for static gesture recognition. On the one hand, such methods have poor recognition effects, especially poor robustness to factors such as illumination, skin color, gesture direction, and image background; on the other hand, such methods It is not easy to integrate hand area tracking and trajectory classification algorithms, and it is impossible to realize interactive response behaviors to dynamic gestures, that is, gesture movement trajectories, and basically cannot meet the needs of human-computer interaction in the context of intelligent homes
Generally speaking, facing the era background of home intelligence, traditional machine learning methods can no longer meet the requirements of robustness, real-time, and accuracy on embedded devices for intelligent human-computer interaction solutions. Therefore, the introduction of deep learning solution, implementing a deep convolutional neural network on embedded devices is an inevitable requirement for the development of smart homes
