  • Ink Features for Diagram Recognition 

    Patel, Rachel; Plimmer, Beryl; Grundy, John; Ihaka, Ross (The Eurographics Association, 2007)
    The ability to automatically recognize a sketch accurately is important to computer-based diagramming. Many recognition techniques have been proposed but few researchers have reported the use of formal methods to select ...
  • Scribbles to Vectors: Preparation of Scribble Drawings for CAD Interpretation 

    Bartolo, A.; Camilleri, K. P.; Fabri, S. G.; Borg, J. C.; Farrugia, P. J. (The Eurographics Association, 2007)
    This paper describes the work carried out on off-line paper based scribbles such that they can be incorporated into a sketch-based interface without forcing designers to change their natural drawing habits. In this work, ...
  • Addressing Class Distribution Issues of the Drawing vs Writing Classification in an Ink Stroke Sequence 

    Wang, Xin; Biswas, Manoj; Raghupathy, Sashi (The Eurographics Association, 2007)
    Complicated by temporal correlations among the strokes and varying distributions of the underlying classes, the drawing/writing classification of ink strokes in a digital ink file poses interesting challenges. In this ...
  • Managing Ambiguity in Mathematical Matrices 

    Tausky, David; Labahn, George; Lank, Edward; Marzouk, Mirette (The Eurographics Association, 2007)
    In this paper we describe strategies for recognizing and using hand drawn matrices in a pen math system. This includes a new technique to recognize common short-forms of writing matrices using ellipsis (. . . ). Ellipsis ...
  • Implicit Geometric Constraint Detection in Freehand Sketches Using Relative Shape Histogram 

    Pu, J.; Ramani, K. (The Eurographics Association, 2007)
    In order to take advantage of the sketch-based interaction, many methods have been proposed to beautify freehand sketches. Most of these efforts are dedicated to sketch segmentation and recognition, while some important ...
  • Designing a Sketch Recognition Front-End: User Perception of Interface Elements 

    Wais, Paul; Wolin, Aaron; Alvarado, Christine (The Eurographics Association, 2007)
    Programs that can recognize students' hand-drawn diagrams have the potential to revolutionize education by breaking down the barriers between diagram creation and simulation. Much recent work focuses on building robust ...
  • Designing UI Techniques for Handwritten Mathematics 

    Zeleznik, Robert; Miller, Timothy; Li, Chuanjun (The Eurographics Association, 2007)
    We discuss the design of user interface techniques for visualizing and controlling the recognition of handwritten mathematics. In particular, we present a range of visualization styles for displaying the result of math ...
  • A Pen-based Tool for Efficient Labeling of 2D Sketches 

    Wolin, Aaron; Smith, Devin; Alvarado, Christine (The Eurographics Association, 2007)
    High quality labeled data is essential for developing and evaluating sketch recognition algorithms. Unfortunately, labeling freely-drawn sketches is time-consuming and difficult, if not impossible, using current technologies. ...
  • Speech and Sketching: An Empirical Study of Multimodal Interaction 

    Adler, A.; Davis, R. (The Eurographics Association, 2007)
    Sketch recognition can capture the sketching component of a multimodal conversation about design, but it does not capture information conveyed in the other modalities. The informal speech that accompanies a sketch often ...
  • Kirchhoff's Pen: A Pen-based Circuit Analysis Tutor 

    Silva, Ruwanee de; Bischel, David Tyler; Lee, WeeSan; Peterson, Eric J.; Calfee, Robert C.; Stahovich, Thomas F. (The Eurographics Association, 2007)
    Kirchhoff 's Pen is a pen-based tutoring system that teaches students to apply Kirchhoff 's voltage law (KVL) and current law (KCL). To use the system, the student sketches a circuit schematic and annotates it to indicate ...
  • CrossSketch: Freeform Surface Modeling with Details 

    Andre, Alexis; Saito, Suguru; Nakajima, Masayuki (The Eurographics Association, 2007)
    This paper presents a novel technique to model a three dimensional freeform surface, in its global shape and small details, using a sketching interface, from a single point of view. In the past, most modeling systems that ...
  • Newton's Pen - A Pen-based Tutoring System for Statics 

    Lee, WeeSan; Silva, Ruwanee de; Peterson, Eric J.; Calfee, Robert C.; Stahovich, Thomas F. (The Eurographics Association, 2007)
    We present Newton's Pen, a statics tutor implemented on a ''pentop computer,'' a writing instrument with an integrated digitizer and embedded processor. The tutor, intended for undergraduate education, scaffolds students ...
  • Free-form Sketch 

    Wang, Haixiong; Markosian, Lee (The Eurographics Association, 2007)
    We describe a sketch-based system for modeling 3D shapes based on a new multiresolution shape representation we call a layered mesh. Like subdivision surfaces, layered meshes provide a multiresolution hierarchy of meshes. ...
  • Example-Based Conceptual Styling Framework for Automotive Shapes 

    Kókai, István; Finger, Jörg; Smith, Randall C.; Pawlicki, Richard; Vetter, Thomas (The Eurographics Association, 2007)
    Conceptual design in the automotive industry is a time-consuming process. Iterations between concept sketches, created with traditional two dimensional methods, and 3D digital representations of a prototype are currently ...
  • Sketching Hairstyles 

    Fu, Hongbo; Wei, Yichen; Tai, Chiew-Lan; Quan, Long (The Eurographics Association, 2007)
    This paper presents an intuitive sketching interface for interactive hairstyle design, made possible by an efficient numerical updating scheme. The user portrays the global shape of a desired hairstyle through a few 3D ...
  • SilSketch: Automated Sketch-Based Editing of Surface Meshes 

    Zimmermann, Johannes; Nealen, Andrew; Alexa, Marc (The Eurographics Association, 2007)
    We introduce an over-sketching interface for feature-preserving surface mesh editing. The user sketches a stroke that is the suggested position of part of a silhouette of the displayed surface. The system then segments all ...
  • A Combinatorial Approach to Multi-Domain Sketch Recognition 

    Hall, A.; Pomm, C.; Widmayer, P. (The Eurographics Association, 2007)
    In this paper we propose a combinatorial model for sketch recognition. Two fundamental problems, the evaluation of individual symbols and the interpretation of a complete sketch scene possibly containing several symbols, ...
  • Temporal Sketch Recognition in Interspersed Drawings 

    Sezgin, Tevfik Metin; Davis, Randall (The Eurographics Association, 2007)
    Sketch recognition has been recognized as an enabling technology for pen-based interfaces. Previous work in the field has shown that in certain domains the stroke orderings used when drawing objects contain temporal patterns ...
