Attentive Navigation Approach
-
Potential camera positions
limited by constraint surface.
-
Ideal viewing parameters
stored in Camera Model Field
-
Collection
of vectors stored in a grid structure
-
Smooth transition ensured with spline
interpolation.
Direct Guidance:
Hiding & Sorting:
-
Gaze is automatically
aligned with ideal viewing vectors.
-
Hiding: Viewer controls
position only, has no control over orientation.
-
Sorting: Viewer can
intervene to override suggested orientation.
Annotation:
-
Ideal viewing vectors
influence the behavior of external imagery, e.g. a flashlight or an
arrow.
-
Improved Recall of Features
-
Improved Sense of Location
-
Improved Search Results
