Facilitating the Parametric Definition of Geometric Properties in Programming-Based CAD
J. Felipe Gonzalez, Thomas Pietrzak, Audrey Girouard +1
Parametric Computer-aided design (CAD) enables the creation of reusable models by integrating variables into geometric properties, facilitating customization without a complete red…
Introducing Bidirectional Programming in Constructive Solid Geometry-Based CAD
J. Felipe Gonzalez, Danny Kieken, Thomas Pietrzak +2
3D Computer-Aided Design (CAD) users need to overcome several obstacles to benefit from the flexibility of programmatic interface tools. Besides the barriers of any programming lan…
Understanding the Challenges of OpenSCAD Users for 3D Printing
J. Felipe Gonzalez, Thomas Pietrzak, Audrey Girouard +1
Direct manipulation has been established as the main interaction paradigm for Computer-Aided Design (CAD) for decades. It provides fast, incremental, and reversible actions that al…
Exploring Geometric Shapes with Touch
Thomas Pietrzak, Andrew Crossan, Stephen A. Brewster +2
We propose a new technique to help users to explore geometric shapes without vision. This technique is based on a guidance using directional cues with a pin array. This is an alter…
U-Note: Capture the Class and Access it Everywhere
Sylvain Malacria, Thomas Pietrzak, Aurélien Tabard +1
We present U-Note, an augmented teaching and learning system leveraging the advantages of paper while letting teachers and pupils benefit from the richness that digital media can b…
Creating Usable Pin Array Tactons for Non-Visual Information
Thomas Pietrzak, Andrew Crossan, Brewster A. Stephen +2
Spatial information can be difficult to present to a visually impaired computer user. In this paper we examine a new kind of tactile cueing for non-visual interaction as a potentia…
