Browsing SBM: Sketch Based Interfaces and Modeling by Issue Date

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 ... 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 ... 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 ... 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 ... 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, ... 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 ... 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 ... 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. ... 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 ... 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 ... 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 ... 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 ... 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. ... 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 ... 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, ... 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 ... 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 ... 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 ... Investigating User Requirements and Usability of Immersive Three-dimensional Sketching for Early Conceptual Design - Results from Expert Discussions and User Studies 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 ... 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 ... Source.
