With research describing that 55 percent of people experience back pain due to working from home and COVID-19 causing everyday individuals to spend more time in front of their screens, posture has become more of an issue than ever. Poor back posture is equivalent to adding 8 kilograms of weight on one’s neck and shoulders. We intend to provide a simple solution for everyday people to be aware of their poor sitting posture and work to correct it over time.
What it does
Our Google Chrome extension analyzes a person’s posture during a computer session and through computer vision, alerts the user with a notification if the user alters to a poor posture. The user is prompted to fix their posture and continue their work, building a habit in the user to be aware of proper sitting posture.
How we built it
Challenges We ran into
Initially, we had trouble getting a video feed from the extension pop-up, because the correct permissions weren’t able to be set. We had to find a workaround that used the options page as a middle man to obtain the correct permissions from the user. Other major challenges derived from integrating the PoseNet model into our application, specifically with accurately mapping the points to the user as well as implementing the thresholds accurately. Eventually, we realized the issue was due to the video display being mirrored and added transformations to the elements to ensure the points were properly matched. We exhaustively searched to determine ideal horizontal and vertical thresholds for every point.
Accomplishments that we're proud of
What we learned
What's next for PostSure
We wish to extend PostSure to be able to provide more detailed statistics about the user’s sitting posture during a session and we plan to create a more personalized interface where users can customize what statistics they wish to view. We would also like to ensure the posture is fixed after the notification by either blocking the screen until the posture is fixed or preventing the user from continuing to work.
