The people with some understanding about how to read an image pixel by pixel would have some understanding about what I am doing here. I am building a program in JavaScript that takes input from the computer's webcam and create a tool that lets you draw in the air and that gets displayed on the computer. For this, we will have a special pen to which we code our program to detect. To get started, let's use the <video> tag to receive the video feed from the camera, which I will later make invisible..

Dhawal and I had worked on a project that would enable reducing the number of sensors involved in order to do the same. In our setup, there would be just two weight sensors placed at a distance and a platform on top of the sensors. We divide the platform into any number and we can determine where each product is placed and if anything is taken away from it, it would automatically change the values. Th...
