Student desk and chair with distraction alert function

By combining the synergy of pressure sensors and millimeter-wave radar with the design of student desks and chairs featuring electric push rods and vibration bars, precise monitoring and reminders of sitting posture and distraction behavior are achieved. This solves the problems of traditional desks and chairs being unable to dynamically adapt to the needs of students' backs and the accuracy of detection, thereby improving students' focus and health.

AI Technical Summary

Technical Problem

Existing student desks and chairs lack effective intervention mechanisms for distraction. Traditional vibration reminder devices are prone to false triggering or have insufficient sensitivity. External sensors are easily affected by environmental interference, cannot dynamically adapt to the back support needs of students of different body types, and have poor accuracy in detecting distracting behaviors.

Method used

The system employs a combination of a pressure sensor and millimeter-wave radar. The pressure sensor acts as a start switch to activate the system, while the electric push rod and electric rotating shaft work together to adjust the backrest. It also features a vibrating stick and a voice player for non-invasive alerts, and the millimeter-wave radar is hidden inside the table to improve detection accuracy.

Benefits of technology

It achieves accurate identification of sitting posture and distraction behavior, reduces energy consumption, improves fit and comfort, and corrects distraction through vibration and voice reminders, forming a closed-loop management system that balances student health and learning focus.
