Technique de 'ray-casting' (Bolt, 1980)
{"Image DocumentName": "Technique de \u2018ray-casting\u2019 (Bolt, 1980)", "Image ImageDescription": "pointeur laser attach\u00e9 \u00e0 la main virtuelle. Le premier objet intersect\u00e9 peut \u00eatre s\u00e9lectionn\u00e9. L\u2019utilisateur a besoin de contr\u00f4ler seulement 2 DOF. Technique simple, qui fonctionne g\u00e9n\u00e9ralement bien. Another common technique is ray-casting. This technique uses the metaphor of a laser pointer \u2013 an infinite ray extending from the virtual hand. The first object intersected along the ray is eligible for selection. This technique is efficient, based on experimental results, and only requires the user to vary 2 degrees of freedom (pitch and yaw of the wrist) rather than the 3 DOFs required by the simple virtual hand and other location-based techniques.
