CITRIS -- BID

• Collaborative Design Environments

• Sara McMains, Carlo Séquin, Paul Wright
• Development of a tele-collaborative designand
  re-design environment for mechanicaland
  geometrical parts.
• Allows designers, managers, manufacturers,located
  on different continents, to jointlyinspect,
  annotate, and modify a design.

Collaborative VR Workstation

• A haptic, immersive work space for
  telecollaborative design across the internet

Collaborative VR Workstation

• A student interacting with a Ford Explorer model
  displayed on the workstation
• (simulated 3D effect showing the part where the
  user perceives it to be).

Model Annotation

• Drawing on a virtual bunny with a brush tool with
  haptic force-feedback.

Séquins Research Interests (1)with Paul Wright
(ME)

• Physical Rapid Prototypes
• For early user testing,
• and hands-on feedback
• in application context.

Research Projects (2) with Paul Wright

• Design for Manufacturability, including Rapid
  Prototyping, and Injection-Mold Making.
• Speeding up Art to Part(or actually
  Inspiration to Income)
• Manufacturing-aware CAD tools.(show
  limitations of fabrication process during all
  design phases.)

Séquins Research Interests (cont.)

• CAD tools for Ideation, Informal Prototyping
• Mimick the best of clay, wire, paper,
  scotch-tape, styrofoam
• Without the adversity of messy glue, gravity,
  strength limits
• 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
