  • O'Connell, Theresa; Li, Chuanjun; Miller, Timothy S.; Zeleznik, Robert C.; Jr., Joseph J. LaViola (The Eurographics Association, 2009)
    AlgoSketch is a pen-based system for entering and editing mathematics. It supports interactive computation and early-stage mathematical algorithm design. In its paper-like environment, mathematical expressions can be en- ...
  • Marinkas, Diane; Zeleznik, Robert C.; Jr., Joseph J. LaViola (The Eurographics Association, 2009)
    We present Shadow Buttons, an approach to placing WIMP interface elements into gestural and sketch-based interfaces. Utilizing the hover state, supported by pen-based devices such as Tablet PCs, we provide users with ...
  • Sowell, R.; Liu, L.; Ju, T.; Grimm, C.; Abraham, C.; Gokhroo, G.; Low, D. (The Eurographics Association, 2009)
    Recent advances in surface reconstruction algorithms [BM07,LBD08] allow surfaces to be built from contours lying on non-parallel planes. Such algorithms allow users to construct surfaces of similar quality more efficiently ...
  • MacLean, Scott; Tausky, David; Labahn, George; Lank, Edward; Marzouk, Mirette (The Eurographics Association, 2009)
    In sketch recognition systems, ground-truth data sets serve to both train and test recognition algorithms. Unfortunately, generating data sets that are sufficiently large and varied is frequently a costly and time-consuming ...
  • Schmidt, Ryan; Khan, Azam; Kurtenbach, Gord; Singh, Karan (The Eurographics Association, 2009)
    A study is described which examines the drawing accuracy of experts when drawing foreshortened projections of 3D curves in ecologically-valid conditions. The main result of this study is that the distribution of error in ...
  • Johnson, Gabe; Do, Ellen Yi-Luen (The Eurographics Association, 2009)
    This article describes sketching games made for the purpose of collecting data about how people make and describe hand-made drawings. The approach leverages human computation, whereby players provide information about ...
  • Field, Martin; Gordon, Sam; Peterson, Eric; Robinson, Raquel; Stahovich, Thomas; Alvarado, Christine (The Eurographics Association, 2009)
    Generating, grouping, and labeling free-sketch data is a difficult and time-consuming task for both user study participants and researchers. To simplify this process for both parties, we would like to have users draw ...
  • Wolin, A.; Paulson, B.; Hammond, T. (The Eurographics Association, 2009)
    Free-sketch recognition systems attempt to recognize freely-drawn sketches without placing stylistic constraints on the users. Such systems often recognize shapes by using geometric primitives that describe the shape's ...
  • Xiong, Yiyan; Jr., Joseph J. LaViola (The Eurographics Association, 2009)
    We present IStraw, a new corner finding technique based on an analysis of the ShortStraw algorithm. Our analysis reveals several limitations in ShortStraw and we develop techniques to overcome them. We also present an ...
  • Hahne, Uwe; Schild, Jonas; Elstner, Stefan; Alexa, Marc (The Eurographics Association, 2009)
    In this paper we present a Focus+Context screen for combined pen and touch interaction. A tabletop display presents contextual information and enables multi-touch detection for navigation through frustrated total internal ...
  • Schmieder, Paul; Plimmer, Beryl; Blagojevic, Rachel (The Eurographics Association, 2009)
    We present our toolkit to automatically evaluate recognition algorithms. There are few published comparative evaluations of sketch recognition algorithms and those that exist do not provide benchmarking or direct comparisons ...
  • Bein, M.; Havemann, S.; Stork, A.; Fellner, Dieter W. (The Eurographics Association, 2009)
    We describe a 3D modeling system that combines subdivision surfaces with sketch-based modeling in order to meet two conflicting goals: ease of use and fine-grained shape control. For the excellent control, low-poly modeling ...
  • Murugappan, S.; Sellamani, S.; Ramani, K. (The Eurographics Association, 2009)
    Beautification of freehand sketches is integral for building robust sketch understanding systems and sketch-based inter-faces for CAD. Many of the current methods for beautification do not consider some important information ...
  • Nasriy, A.; Karam, W. Bou; Samavati, F. (The Eurographics Association, 2009)
    Designing a control mesh (or a polyhedron) for a subdivision model is a tedious task. It involves many difficult decisions such as how to minimize the number of extraordinary vertices, how best to choose their valencies, ...
  • Eyiyurekli, M.; Grimm, C.; Breen, D. (The Eurographics Association, 2009)
    Level set models are deformable implicit surfaces where the deformation is controlled by a speed function in the level set partial differential equation (PDE). These models are widely used in computer graphics applications ...
  • Kraevoy, Vladislav; Sheffer, Alla; Panne, Michiel van de (The Eurographics Association, 2009)
    Occlusion contours are a natural feature to draw when tracing an object in an image or when drawing an object. We investigate the development of 3D models from multi-stroke contour drawings with the help of a 3D template ...
  • Eitz, Mathias; Hildebrand, Kristian; Boubekeur, Tamy; Alexa, Marc (The Eurographics Association, 2009)
    We address the problem of large scale sketch based image retrieval, searching in a database of over a million images. The search is based on a descriptor that elegantly addresses the asymmetry between the binary user sketch ...
  • Ventura, J.; DiVerdi, S.; Höllerer, T. (The Eurographics Association, 2009)
    We present sketch-based tools for single-view modeling which allow for quick 3D mark-up of a photograph. With our interface, detailed 3D models can be produced quickly and easily. After establishing the background geometry, ...
  • Lopes, Ricardo; Cardoso, Tiago; Silva, Nelson; Fonseca, Manuel J. (The Eurographics Association, 2009)
    Over the last years, amateur artists have been using the new Internet technologies to easily produce, share and distribute their comics. However, web applications for this kind of creation are still restricting users by ...
  • Gross, M. D. (The Eurographics Association, 2009)
    Research on sketching with computers dates to the earliest days of modern computing. Recent work in this area, combined with other advances in hardware and software technologies promises, finally, significant impact. The ...
