3.1 Terms and definitions

For the purposes of this document, the following terms and definitions apply.

ISO and IEC maintain terminological databases for use in standardization at the following addresses:

—  ISO Online browsing platform: available at www.iso.org/obp

—  IEC Electropedia: available at www.electropedia.org

3.1.1
channel

motion-capture transformation parameter

Note 1 to entry: Each channel represents a degree of freedom for transformation. For example, there are three channels at an elbow joint for motion-capture.

3.1.2
frame

electronically coded still image

3.1.3
frame time

time for displaying a still image

3.1.4
human behaviour

specific motions that represent movement possible in a human being

3.1.5
inverse kinematics
IK

mathematical process of recovering the movements of an object in the world from some other data

3.1.6
motion-capture
mocap

process of recording the articulated movement of objects or people

3.1.7
motion-capture data

set of changes in position and orientation, corresponding to a specific skeleton, that result from motion-capture operations

3.1.8
motion-capture figure

human (or other) figure that is the original source of motion-capture data being sensed

3.1.9
motion data

set of changes in position and orientation that embodies a full set of motion for all HAnim joints being animated

3.1.10
motion data animation

processing of motion data to generate animation sequences for HAnim figures

3.1.11
motion definition

specific change of position or orientation of an HAnim joint

3.1.12
motion editor

program that can modify and display the motion of an HAnim figure by adjusting the motion parameters

3.1.13
motion parameters

set of variables that control the actions of a single motion definition

3.1.14
motion sensor

sensor that detects positional and orientation changes in the motion-capture figure

3.1.15
motion viewer

program that allows motion-capture data to be displayed as an animation of HAnim figures

3.1.16
rigging

process of connecting the HAnim figure with the animation controls
