CITRIS -- BID Collaborative Design Environments Sara McMains, Carlo Séquin, Paul Wright Development of a tele-collaborative design and re-design environment for mechanical and geometrical parts. Allows designers, managers, manufacturers, located on different continents, to jointly inspect, annotate, and modify a design.

Collaborative VR Workstation A haptic, immersive work space for telecollaborative design across the internet See in 3D, Touch, feel, Annotate, Modify, Share, Discuss …

Séquin’s Research Interests (1) with Paul Wright (ME) Physical Rapid Prototypes: l For early user testing, l and hands-on feedback l in application context. Zcorp 3D-printer FDM

Research Projects (2) with Paul Wright Design for Manufacturability, including Rapid Prototyping, and Injection-Mold Making. l Speeding up “Art to Part” (or actually: “Inspiration to Income”) l “Manufacturing-aware” CAD tools. (show limitations of fabrication process during all design phases.) Vague Idea Concept Mock-up CAD Model Proc.Plan, CNC File Prototype Part Commercial Product

Séquin’s Research Interests (cont.) CAD tools for Ideation, Informal Prototyping: l Mimick the best of: clay, wire, paper, scotch-tape, styrofoam … l Without the adversity of: messy glue, gravity, strength limits … l Make available pseudo-physical materials that bend as nicely as steel wire, and stretch like a nylon hose, but are strong as titanium, and as transparent as quartz …

Séquin’s Research Interests (4) Continue to explore the “Art-Math” connection …
