Exploring Usability and Learnability of Mode Inferencing in Pen/Tablet Interfaces
(The Eurographics Association, 2010)
The inferred mode protocol uses contextual reasoning and local mediators to eliminate the need to access specific modes to perform draw, select, move and delete operations in a sketch interface. In this paper, we describe ...
Tools for the Efficient Generation of Hand-Drawn Corpora Based on Context-Free Grammars
(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 ...
Parts, Image, and Sketch based 3D Modeling Method
(The Eurographics Association, 2006)
Despite their many benefits, challenges exist in the creation of 3D models, particularly for individual not currently skilled with 3D modeling software. To address this, we explore the creation of 3D modeling software for ...
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 ...
Managing Ambiguity in Mathematical Matrices
(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 ...
