Technical Field

[0001] This utility model belongs to the field of smart wearable device technology, and in particular relates to a smart sedentary reminder belt with a voice assistant. Background Technology

[0002] In modern life, prolonged sitting has become a common problem that endangers public health. Medical research shows that sitting for more than 30 minutes can increase the pressure on the lumbar intervertebral discs by 40%, change the physiological curvature of the cervical spine, and over time easily lead to chronic diseases such as lumbar muscle strain and cervical degenerative diseases.

[0003] Current sedentary reminder devices on the market face significant technical bottlenecks: single-sensor devices (such as simple accelerometers) are prone to misjudgment due to slight movements, with a monitoring accuracy of less than 70%; products that rely on GPS or Bluetooth networking often experience delayed reminders in classrooms, conference rooms, and other scenarios due to unstable signals; and high-end products with data analysis capabilities are generally expensive, making it difficult to popularize among students.
