Final Project Preliminary Concept : Drawing With Motion
For my final project, I will design an interactive hand-controlled drawing device that allows users to sketch on a digital canvas by waving their hand in the air. I will use a distance sensor to track the distance of a hand from the sensor. The distance information will be sent to p5.js, which will use iit to manage various features of a virtual brush, like how it draws and how thick the lines will be. Thus, the graphics in p5.js will change instantly according to the user’s hand movements. For instance, as the hand moves closer to the sensor, the brush could create bolder, thicker lines. However, bringing the hand farther away might result in thinner lines. The system allows individuals to “paint” on the screen without using a mouse or stylus at all.
The p5.js sketch on the screen will show a white canvas featuring a circular brush that moves in sync with the user’s hand motions. When the user holds their hand over the sensor, the brush will emerge and begin drawing as they move their hand side to side. To clarify when to begin, the canvas will show a “Place your hand to start” message. As soon as a hand is identified near the sensor, the message will vanish and drawing will start automatically. In addition, it might be possible to add a color wheel for the user to click the desired color when “painting” on p5.
Once the user finishes their drawing, they can easily press a button next to the distance sensor. After pressing, the canvas will pause and show a cheerful message: “Awesome! “Thanks for your artwork!” In a few seconds, the sketch will return to the starting screen, prepared for the next attempt to draw.
