Problems solved by technology

Wearable sensors are not affected by changes in light, but it is inconvenient to wear and the user experience is poor
Compared with cameras, passive infrared sensors are more robust to light changes, but they are not flexible enough and are less effective in recognizing complex behaviors.
At the same time, the method of using geometric logic to recognize human behavior is widely used in the product market due to its simplicity, efficiency, and good adaptability, but it is difficult to meet the relatively complex behavior recognition needs.
The Bayesian human body recognition method requires a small amount of data and perfect theory, which is suitable for sensor human body recognition, but the recognition effect on complex behaviors and difficult-to-describe similar behaviors in continuous time is poor
