Mix brush: An interactive digital painting tool with shaking interaction and color feedback

In this paper, we present an interactive digital brush, which invites people to create a work of art with mixing colors. The Mix Brush aimed at enriching traditional screen based interactions with shaking interaction and color feedback. It was created using a tablet pen and the RGB Light-emitting Diode (LED). The tablet pen enables tracking of the contact point of brush on the interactive display, and RGB LEDs presents the picked up colors. People are able to do their creative activities on the interactive display with our own brush and software. The Mix Brush approaches two important properties: immediate indication of the selected colors with LEDs and mixing colors with shaking the brush. Pilot study shows that this interactive digital brush enhances the user experience (UX) and it capable of applying to child education.
