The material and presenting it on the screen using the application is a part of the interaction that is possible through the computer vision air canvas. Having the various colours present is also a part of this interaction. The varied colour schemes make it easier for the user to identify things and provide greater clarity. Accessing the built-in web camera on the laptop or the independent web camera that was installed is required to accomplish this. This contributes to a better overall knowledge and provides the user with a more concise description of the air. In addition to that, this is utilised for text visualisation and drawing for the audience. This has the potential to serve as a stepping stone for more innovative streams and material that is engaging in the future. Simply moving your finger through the air will allow you to draw your creative ideas, which does make use of computer vision technology. In the respective paper, we construct a screen through which the information or text that we draw by waving is displayed appropriately on the screen for which is done by employing shooting the motion of finger using internet digital camera. This is accomplished in a manner similar to how a touch screen works. The detection of the colours, tracking of the marker, and establishment of the coordinates are the objectives of this particular piece of writing.
