CogSketch: Open-domain Sketch Understanding for Cognitive Science Research and for Education
(The Eurographics Association, 2008)In this paper, we describe CogSketch, an open-domain sketch understanding system built on the nuSketch architecture. CogSketch captures the multi-modal, unconstrained nature of sketching by focusing on reasoning over ... -
Automatic Interpretation of Depiction Conventions in Sketched Diagrams
(The Eurographics Association, 2008)Diagrams are used in many educational settings to convey physical and spatial information. Sketching is used, in turn, to test students' understanding of course concepts. The availability of Tablet PCs offer an exciting ... -
AlgoSketch: Algorithm Sketching and Interactive Computation
(The Eurographics Association, 2008)We present AlgoSketch, a pen-based algorithm sketching prototype with supporting interactive computation. AlgoSketch lets users fluidly enter and edit 2D handwritten mathematical expressions in the form of pseudocode-like ... -
Supporting Reinterpretation in Computer-Aided Conceptual Design
(The Eurographics Association, 2008)This paper presents research that aims to inform the development of computational tools that better support design exploration and idea transformation - key objectives in conceptual design. Analyses of experimental data ... -
MathBrush: A Case Study for Pen-based Interactive Mathematics
(The Eurographics Association, 2008)Current generations of computer algebra systems require users to transform two dimensional math expressions into one dimensional strings, to master complex sets of commands, and to analyze lengthy output strings for relevant ... -
Investigating User Requirements and Usability of Immersive Three-dimensional Sketching for Early Conceptual Design - Results from Expert Discussions and User Studies
(The Eurographics Association, 2008)As immersive 3-d user interfaces reach broader acceptance, their use as sketching media is attracting both commercial and academic research. So far little is known about user requirements and cognitive aspects of immersive ... -
An Empirical Study in Pen-Centric User Interfaces: Diagramming
(The Eurographics Association, 2008)We present a user study aimed at helping understand the applicability of pen-computing in desktop environments. The study applied three mouse-and-keyboard-based and three pen-based interaction techniques to six variations ... -
Rapid Sketch Modeling of Clouds
(The Eurographics Association, 2008)Clouds are an important visual element of any natural scene and computer artists often wish to create specific cloud shapes (for example in the film Amélie, as depicted in Fig 1). We describe a sketch based interface for ... -
Sketch-based Parameterization of L-systems using Illustration-inspired Construction Lines
(The Eurographics Association, 2008)We present a sketch-based interface for parameter control of rule-based models. It allows intuitive specification and creation of plant structures with L-systems. Construction lines inspired by concept sketches are employed ... -
Sketch-Based Search and Composition of 3D Models
(The Eurographics Association, 2008)There is growing interest in developing tools with which novice users can create detailed 3D models of their own designs. The most popular approaches to this problem include sketch-based interfaces and part-composition ... -
Sketching Faces
(The Eurographics Association, 2008)Faces can be modelled using a number of techniques. Existing faces can be transferred to a digital form using equipment such as laser scanners. New faces can be constructed using commercial modelling tools, or using ... -
SOUSA: Sketch-based Online User Study Applet
(The Eurographics Association, 2008)Although existing domain-specific datasets are readily available, most sketch recognition researchers are forced to collect new data for their particular domain. Creating tools to collect and label sketched data can take ... -
Using Sketches and Retrieval to Create LEGO Models
(The Eurographics Association, 2008)In this paper we describe a system to create LEGO models using sketches. Although there are a few applications to create LEGO models, they are difficult to use, mainly due to the searching and manipulation mechanisms that ... -
A Data Collection Tool for Sketched Diagrams
(The Eurographics Association, 2008)Repositories of digital ink sketches would be invaluable for testing and evaluation of sketch recognition software. However, there is no existing tool for flexible data collection and management of digital ink data for ... -
From Paper to Machine: Extracting Strokes from Images for use in Sketch Recognition
(The Eurographics Association, 2008)Sketching is a way of conveying ideas to people of diverse backgrounds and culture without any linguistic medium. With the advent of inexpensive tablet PCs, online sketches have become more common, allowing for stroke-based ... -
Repoussé: Automatic Inflation of 2D Artwork
(The Eurographics Association, 2008)We describe a new system for the interactive enhancement of 2D art with 3D geometry. Repoussé creates a 3D shape by inflating the surface that interpolates the input curves. By using the mean curvature stored at boundary ... -
Matisse: Painting 2D regions for Modeling Free-Form Shapes
(The Eurographics Association, 2008)This paper presents Matisse, an interactive modeling system aimed at providing the public with a very easy way to design free-form 3D shapes. The user progressively creates a model by painting 2D regions of arbitrary ... -
A Sketch-Based Method to Control Deformation in a Skeletal Implicit Surface Modeler
(The Eurographics Association, 2008)Skeletal implicit surfaces offer many advantages for sketch-based modeling systems, such as blending, CSG, and a procedural object hierarchy. Free-form deformation (FFD) is also extremely useful in this context, however ... -
ShortStraw: A Simple and Effective Corner Finder for Polylines
(The Eurographics Association, 2008)In this paper we introduce ShortStraw, a simple and highly accurate polyline corner finder. ShortStraw uses a bottom-up approach to find corners by: (1) resampling the points of the stroke, (2) calculating the straw ... -
Paper-based Scribble Simplification:Where Do We Stand?
(The Eurographics Association, 2008)This paper presents a formal evaluation of the paper-based scribble simplification algorithm described in [BCFB07] and [BCFB08]. A comparative analysis of different aspects of the algorithm with other algorithms described ...
