The problem

During and after the pandemic, remote work increased in the whole world, and people started working on places that were not necessarily made for them to work on for 8 hours. Keeping good posture in the workplace is essential to maintain a healthy life, but when you work from home this can become a hard task.

The project

The project consists of implementing a system to verify if a person is seated properly while working, according to good ergonomics. The verification of the person's posture will be done through capacitive sensors on the person’s chair, additionally the arms angle and the head view angle will be monitored using a camera . The system will check the person's position periodically, and it will give tactile feedback if a bad posture is detected. The system will alert if the person has been seated for too long and suggest stretches throughout the day.
