Merging Sketches for Creative Design Exploration: An Evaluation of Physical and Cognitive Operations

by Convergence Design Lab Admin | May 16, 2017 | 2017, Design Collaboration, Recent Publications, Senthil Chandrasegaran, Uncategorized

Despite its grounding in creativity techniques, merging multiple source sketches to create new ideas has received scant attention in design literature. In this paper, we identify the physical operations that in merging sketch components. We also introduce cognitive...

VizScribe: A visual analytics approach to understand designer behavior

by Convergence Design Lab Admin | Jan 16, 2017 | 2017, Design Collaboration, Design Learn, DESIGN METHOD, Design Representation, Karthik Ramani, Recent Publications, Senthil Chandrasegaran

Design protocol analysis is a technique to understand designers’ cognitive processes by analyzing sequences of observations on their behavior. These observations typically use audio, video, and transcript data in order to gain insights into the designer’s...

WireFab: Mix-Dimensional Modeling and Fabrication for 3D Mesh Models

by Convergence Design Lab Admin | Dec 30, 2016 | 2017, DESIGN METHOD, Fabrication, Jeff Alperovich, Jing Bai, Karthik Ramani, Min Liu, Recent Publications, TANGIBLE, EMBEDDED & EMBODIED INTERFACES, Tangibles, Yuanzhi Cao, Yunbo Zhang

We propose WireFab, a rapid modeling and prototyping system that uses bent metal wires as the structure framework. WireFab approximates both the skeletal articulation and the skin appearance of the corresponding virtual skin meshes, and it allows users to personalize...

Window-Shaping: 3D Design Ideation by Creating on, Borrowing from, and Looking at the Physical World

by Convergence Design Lab Admin | Dec 26, 2016 | 2017, DESIGN METHOD, HUMAN SHAPE INTERACTION, Karthik Ramani, Ke Huo, Multi-touch Interaction, Recent Publications, Vinayak

We present, Window-Shaping, a tangible mixed-reality (MR) interaction metaphor for design ideation that allows for the direct creation of 3D shapes on and around physical objects. Using the sketch-and-inflate scheme, our metaphor enables quick design of dimensionally...

Co-3Deator: A Team-First Collaborative 3D Design Ideation Tool

by Convergence Design Lab Admin | Dec 26, 2016 | 2017, Cecil Piya, Design Collaboration, Design Representation, Karthik Ramani, Multi-touch Interaction, Publications, Recent Publications, Senthil Chandrasegaran, Vinayak

We present Co-3Deator, a sketch-based collaborative 3D modeling system based on the notion of “team-first” ideation tools, where the needs and processes of the entire design team come before that of an individual designer. Co-3Deator includes two specific...

Developing Middle School Students’ Engineering Design Concepts through Toy Design Workshop

by Convergence Design Lab Admin | Aug 29, 2016 | 2016, Design Collaboration, Design Learn, DESIGN METHOD, Design Representation, Publications, Senthil Chandrasegaran, Tarun George

In this study, we structured a toy design workshop to provide hands on and engaging design activities for middle school students, to help them develop self-efficacy beliefs in design, model and scaffold engineering design mindsets, and apply design concepts in...
