An interactive drawing tool aimed at young children, ages four and up, to
explore colors, textures, and movements found in everyday materials by
"picking up" and drawing with them. The tool looks and feels like a
conventional hand-held paintbrush but has a small video camera with
lights and touch and orientation sensors embedded inside. Outside of the
drawing canvas, the brush can pick up color, texture, and movement of a
brushed surface, either from objects or surfaces, or from an electronic
palette that stores captured images and colors for repeated use and may
be implemented by a tablet computer. On the canvas, children can draw
with the special "ink" they just picked up from their immediate
environment. The canvas comprises a display screen combined with a brush
position sensor coupled to a personal computer which also receives image
and control data from the brush.
