• ..motions of the limbs or body made to express or help express thought or to emphasise speech.

• ..the actions of making such a motion or motions.

Gestural activity and Gesture intentions

Gestures are: mimic gesture, symbolic gestures, sweeping, sign language, speech-connected hand gesture, surface-based gestures and whole-body interaction and can be expressed in 2D and 3D:

Besides the act of making motion, gestures can have a specific intent as well. These are called gesture intentions, of which different examples can be seen here: Float, Wring, Dab, Glide, Punch, Press, Flick, Slash. As you can see these intentions are quite refined and it needs some practice to extinguish them from one another. One way of applying these gesture intentions is by creating characters for avatars.

Gestural Kinesphere

Kinespheres can be used on a variety of scales, from the human body to small thumb-movements. In this chapter, we ask you to think about the gestural kinesphere

• kinespheres on a variety of scales

• gestural kinesphere for hand & fingers (small-scale)

• example of gestural movement

Other examples of gestural movement

• Grasping - Hand-based grasping (simple virtual hand & Go-Go interaction technique) - 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) - Volume-based pointing technique (flashlight, aperture selection, sphere-casting) - Enhancements (bend cast, depth ray, absolute & relative mapping)

• Surface - (2D)dragging and rotating - (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 - Indirect Proxy Techniques: world in miniature, Voodoo Dolls - Indirect Widget Technique: 3D widgets, virtual sphere, arcball.
