Area of Science:

Biomedical Engineering
Human-Computer Interaction
Ergonomics

Background:

Prolonged sitting with poor posture contributes to musculoskeletal issues like back and neck pain.
Effective sitting posture recognition is vital for health during work and study.
Current pressure sensor systems achieve 80-90% accuracy, indicating a need for enhanced solutions.

Purpose of the Study:

To develop an advanced sitting posture recognition system (SPRS).
To improve the accuracy and usability of recognizing common sitting postures.

Main Methods:

Identified critical chair surface areas for capturing posture data.
Utilized diverse machine learning algorithms for posture classification.
Evaluated system performance with 20 volunteers in a 10-minute session.

Main Results:

SPRS achieved a high accuracy rate of up to 99.1% in recognizing ten common sitting postures.
Usability surveys (SUS, QUIS) confirmed the system is user-friendly, easy to operate, and responsive.

Conclusions:

The developed SPRS significantly enhances sitting posture recognition accuracy.
SPRS offers a practical and user-friendly solution for promoting better sitting habits.
This technology has the potential to mitigate health issues associated with poor posture.
