Dab

Abstract

We present a novel painting system with an intuitive haptic interface, which serves as an expressive vehicle for interactively creating painterly works. We introduce a deformable, 3D brush model, which gives the user natural control of complex brush strokes. The force feedback enhances the sense of realism and provides tactile cues that enable the user to better manipulate the paint brush. We have also developed a bidirectional, two-layer paint model that, combined with a palette interface, enables easy loading of complex blends onto our 3D virtual brushes to generate interesting paint effects on the canvas. The resulting system, DAB, provides the user with an artistic setting, which is conceptually equivalent to a real-world painting environment. Several users have tested DAB and were able to start creating original art work within minutes.

Multilayer Haptic Feedback for Pen-Based Tablet Interaction

“…While haptic cues work within the non-visual sensory channel, they also afford eyes-off interaction, another area that deserves follow-up. In addition, it will be interesting to assess to what extend the system can improve expressiveness [4,75].…”

“…Pen-based tactile cues improve user performance (affected by a learning-curve [51]), especially for smaller targets [63]. General interaction with touchscreens [11,45,48], or artistic and writing applications [4,13,18] and education [53] have been explored. These systems often provide feedback similar to haptic mice [1] or pens for spatial interaction [17,37,44].…”

“…Tactile or kinesthetic cues enhance the operation of tools that exhibit "elastic" properties. Such cues can enhance the experience and potentially also performance with such tools [4,75], as these cues provide indications of the realworld haptic properties that help the user understand how the tool performs while using it. We highlighted the potential of such cues in our art application, where the experience of different brush properties subjectively enhanced interaction.…”

“…Haptic features have been shown to improve user performance [40]. Tactile cues -which can substitute kinesthetic ones -can enhance performance [6], improving expressiveness [4,75], perceptual accuracy and nonambiguity [50]. However, not all haptic properties can be transferred during sensory substitution [35].…”

Gradient Art: Creation and Vectorization

“…Tools may tightly simulate their real-world counterparts (e.g., [2]), or they might provide novel types of interactions (e.g., [18]). In both cases though, users create color gradients by layering multiple strokes.…”
