Techniques for selection and manipulation

article 1: Hands and Speech in Space

Grasping: Hand-based grasping (simple virtual hand & Go-Go interaction technique) and finger-based grasping (rigid-body fingers, soft-body fingers, god fingers)
Pointing: vector-based pointing technique (ray-casting/ray-tracing, fishing reel, image-plane pointing) and volume-based pointing technique (flashlight, aperture selection, sphere-casting) and enhancements (bend cast, depth ray, absolute & relative mapping)
Surface: (2D)dragging and rotating and (3D) pinching, void shadows, balloon selection, corkscrew widget, triangle cursor
Indirect: Indirect Control-Space: indirect touch, virtual interaction surface, levels-of-precision cursor, virtual pad and Indirect Proxy Techniques: world in miniature, Voodoo Dolls and Indirect Widget Technique: 3D widgets, virtual sphere, arcball.

Hybrid

Selection: specifying one of more objects from a set.

Goals of selection: indicate action on object, Query object, Make object active, Travel to object location, Set up manipulation

Selection performance: variables affecting user performance, Object distance from user, Object (visual) size, Density of objects in area, Occluders
