Seminar on Haptics
[attachment=26130]
Goals
Avoid complex/cumbersome devices
Intuitive/simple interaction metaphors
Two hands are better than one
Physical/virtual constraints
Increase precision
Reduce fatigue
Visual Haptic Workbench
LCD frame-sequential 3-D glasses
Fakespace Immersive Workbench
Polhemus Fastrak magnetic trackers
Epicardial Muscle
Probe constrained to muscle fiber in a surface layer
User can ‘‘pop through’’ to next layer by pushing against the surface.
User can choose different fiber by pushing perpendicular
Feels as if surface is textured with tiny valleys and ridges
Proxy path colored by applied force mag. perp. to fiber tangent to surface from yellow to cyan
Diffusion Tensor MRI
Diffusion displayed in glyphs
Proxy path colored by applied force magnitude, from yellow to red indicating tension as before
Curves follow major eigenvector streamlines
