Abstract
The creation process in digital art relies often on collaborations between an artist (or group of artists) and a multidisciplinary team. This collaboration implies a multidisciplinary work involving art, science, technology, design, psychology, etc. that come together by sharing a common communicational and informational space.In this essay we bring into discussion how the creation process cycle in digital art could be instantiated and applied for the development of serious games through end-user purposes of both creative authors: the digital artists and the serious games developers. We realise a comprehensive analysis of this creation process in digital art, specially the aesthetic musing activity, while devising how it could be helpful to introduce new engaging stimulus in the creative process of serious games. © 2010 International Federation for Information Processing.

Abstract
NUVE is an artistic project that aims to explore the artistic possibilities offered by the digital dance performances in the interaction between the individual and his virtual double. In NUVE we conceptualized, developed and implemented a digital artifact, resulting in a fluid digital performance based on the theme of the analog body versus the digital virtual body.

Abstract
Presently, multi-touch interactive surfaces have widespread adoption as entertainment devices. Taking advantage of such devices, we present an interactive LEGO application, developed accordingly to an adaptation of building block metaphors and direct multi-touch manipulation. Our solution (LTouchIt) allows users to create 3D models on a tabletop surface. To prove the validity of our approach, we compared LTouchIt with two LEGO applications, conducting a user study with 20 participants. The results suggest that our touch-based application can compete with existing mouse-based applications. It provides users with a hands-on experience, which we believe to be more adequate for entertainment purposes.

Abstract
Recently, considerable research has been carried out regarding three-dimensional object manipulation on multi-touch surfaces. However, most current solutions were developed having in mind scenarios with a camera perpendicular to a scene axis, and cannot be easily used to manipulate three-dimensional objects in unconstrained viewpoints. In this paper, we present and evaluate a set of object manipulation techniques. As a test bed for this study, we used an unconstrained virtual LEGO modeling tool, taking advantage of ongoing work and popularity of LEGO construction among people of all ages. From this evaluation we improved our understanding on how users prefer to manipulate 3D objects on multi-touch surfaces.

Abstract
Multitouch enabled surfaces can bring advantages to modelling scenarios, in particular if bimanual and pen input can be combined. In this work, we assess the suitability of multitouch interfaces to 3D sketching tasks. We developed a multitouch enabled version of ShapeShop, whereby bimanual gestures allow users to explore the canvas through camera operations while using a pen to sketch. This provides a comfortable setting familiar to most users. Our contribution focuses on comparing the combined approach (bimanual and pen) to the pen-only interface for similar tasks. We conducted the evaluation helped by ten sketching experts who exercised both techniques. Results show that our approach both simplifies workflow and lowers task times, when compared to the pen-only interface, which is what most current sketching applications provide. © 2011 ACM.
