In this paper we report on our work to develop a novel input technique for a digital paint system. Using a brush with infrared (IR) light emitting fibers, we were able to create a natural paint interface on an interactive table. This IR-brush adds two important properties to our paint environment: haptic feedback and an accurate brush footprint. The modified brush approaches the haptic feedback of the traditional paint brush. The use of IR-light in the brush enables tracking of the contact area
