    To determine appropriate computer science curricula, educators sought to better understand the different affordances of teaching with a visual programming language (Alice) or a text-based language (Jython). Although students often preferred one language, that language wasn't necessarily the one from which they learned the most. View full abstract»

    Proper lighting in rendering is essential for visualizing 3D objects, but most visualization software tools still employ simple lighting models. The advent of hardware-accelerated advanced lighting suggests that volume visualization can be truly usable for clinical work. Researchers studied how volume rendering incorporating global illumination impacted perception of bone surface features captured... View full abstract»

    Visualization is coming of age. With visual depictions being seamlessly integrated into documents, and data visualization techniques being used to understand increasingly large and complex datasets, the term "visualization"' is becoming used in everyday conversations. But we are on a cusp; visualization researchers need to develop and adapt to today's new devices and tomorrow's technology. Today, ... View full abstract»

    Humans are emotional beings, and their feelings influence how they perform and interact with computers. One of the most expressive modalities for humans is body posture and movement, which researchers have recently started exploiting for emotion recognition. This survey describes emerging techniques and modalities related to emotion recognition based on body movement, as well as recent advances in... View full abstract»

    Electroencephalography (EEG) is a novel modality for investigating perceptual graphics problems. Until recently, EEG has predominantly been used for clinical diagnosis, in psychology, and by the brain-computer-interface community. Researchers are extending it to help understand the perception of visual output from graphics applications and to create approaches based on direct neural feedback. Rese... View full abstract»

  • Multispectral Photometric Stereo for Acquiring High-Fidelity Surface Normals

    Multispectral imaging and photometric stereo are common in 3D imaging but rarely have been combined. Reconstructing a 3D object's shape using photometric stereo is challenging owing to indirect illumination, specular reflection, and self-shadows, and removing interreflection in photometric stereo is problematic. A new multispectral photometric-stereo method removes interreflection on diffuse mater... View full abstract»

    The more-or-less artificial barrier between information visualization and scientific visualization hinders knowledge discovery. Having an integrated view of many aspects of the target data, including a seamlessly interwoven visual display of structural abstract data and 3D spatial information, could lead to new discoveries, insights, and scientific questions. Such a view also could reduce the user... View full abstract»

    Spatial augmented reality applies the concepts of spatial user interfaces to large-scale, projector-based augmented reality. Such virtual environments have interesting characteristics. They deal with large physical objects, the projection surfaces are nonplanar, the physical objects provide natural passive haptic feedback, and the systems naturally support collaboration between users.

    Using random per-element luminance modulation can increase the visual salience of details in a range of visualizations (2D, 3D, and ND scalar, vector, and tensor fields). Although random luminance has been used in specific designs, its wide applicability isn't reflected in visualizations, perhaps because it hasn't yet been presented as a cross-cutting technique. Adding random-luminance contrast ca... View full abstract»
