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.
