# Embodiment: Gestural Kinesphere

## Gestural Kinesphere

#### Gestures are

* ..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](https://www.youtube.com/watch?v=Axtrk4KniCw), [Wring](https://www.youtube.com/watch?v=7rvs87Fa3NY), [Dab](https://www.youtube.com/watch?v=dHJD0X-fa9E), [Glide](https://www.youtube.com/watch?v=8gv_hZfHels), [Punch](https://www.youtube.com/watch?v=Y6DJSNpwlts), [Press](https://www.youtube.com/watch?v=Q3dLyEzhr0s), [Flick](https://www.youtube.com/watch?v=BXabAJFNv8s), 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. (see video for a good impression)

### 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
