Other systems rely on the skills of the video analyst to abstract the principle features of interaction in terms of constructs such as personality or mood. This coding scheme uses a three-dimensional scale consisting of three spatial dimensions which are mapped into three psychological dimensions. The behavioral level consists of both overt and non-verbal behavior. The interpretive level records the meaning conveyed by behavioral acts as opposed to the acts themselves. Each subject is represented as a circle where the radius of the circle conveys dominance information.
Larger circles indicate more dominant behavior.
Much of video data analysis currently consists of techniques borrowed from other disciplines. We can expect that a variety of new methods of data analysis specifically targeted to the requirements of video data will be developed in the future as more researchers work with video, and with sequential data transcribed or abstracted from the raw video record.
