Immersive graph navigation using direct manipulation and gestures
Noritaka Osawa, Kikuo Asai, Yuji Y. Sugimoto · 2000
An immersive graph visualization and navigation system is proposed. Its visualization is based on a multiple-focus layout technique using heat models. Virtual temperatures influence the graph layout. The navigation uses a combination of the layout technique and hand gestures. The system allows one to have multiple-focus nodes and to move a focus by direct manipulation and hand gestures dynamically. Direct manipulation by hand can arrange nodes and choose focus nodes. Hand gestures can control a focus area using a spotlight-like heat radiation, A forefinger points the direction of the spotlight and an angle between the forefinger and the thumb controls a spread angle of the spotlight. This technique enables one to navigate a graph in an immersive virtual space.
