Virtual Painter

A simple program that allows you to draw with your finger on the webcam view.

The program allows switching between 3 different colors (Red, Green, Blue) and 1 eraser. Color and eraser selection boxes do not appear on the screen until a hand is detected on the webcam.

Usage

In order to use the program, a hand must first be detected on the webcam. The program works with only one hand; two-handed operation is not possible.

To choose a color or eraser:

• Raise your index and middle fingers together and move them to the corresponding box. The text "Select" will appear in the lower-right side of the window.

• Each box allows its own color to be selected; select the black box for the eraser.

• By default, the program starts with the red color selected.

To draw:

• Raise your index finger and start drawing. The text "Draw" will appear in the lower-right side of the window.
• As long as your index finger stay raised, you can draw. Lower your finger to stop drawing.
