To have a proper posture, you need to stay upright while sitting. This website is designed to help you achieve this by warning you whenever you are not sitting upright.
To use this site effectively, all you have to do is:
1.When asked by the browser, give permission to utilize the webcam.
2.Sit in a proper position (upright) and click the Right Position button a few times. (15-20 is usually enough). Each time you press the button it captures an image and trains the machine learning algoritmh with it. So to get good results, be sure to look at different parts of the screen, lean a bit to the right/left etc.
3.Next, sit in a wrong position, (NOT upright) and click the Wrong Position button a few times. (15-20 is usually enough). Again, try looking at different parts of the screen, etc.
4.After doing all these steps, you are ready to go. Leave the website open and it will warn you with sound/viusals whenever you start siting in a wrong posiiton.
5.If you think it is not working accurately enough, try adding more right position/wrong position samples.
