Path Drawing for 3D Walkthrough
Demostration Movie (mpeg, 7MB)
We propose a new walkthrough technique that
allows the user to navigate through a 3D virtual workspace using
a hand-drawn trajectory on a 2D screen.
A free stroke trajectory drawn on the 2D screen is projected onto
the ground in the virtual 3D workplace, and
the viewpoint moves along the projected trajectory.
This technique is more comfortable than conventional
navigation techniques where the user controls
the direction and speed of viewpoint movement continuously.
It is also superior to the
target specification technique in that the user can
specify both location and direction at once.
Experimental results showed that path drawing technique
can improve the user's satisfaction without causing
unnecessary overhead.
