Dissertation Abstract:

This dissertation presents the theory and application of Gesture Form
Analysis, which systematises necessary processes of spatial conceptualisation
for understanding a specific gesture type (pointing, drawing, representing
etc.). Eight gesture form operations are proposed, which are combined in a
modular fashion. They are applied in the analysis of gestures of the
dissertation corpus and of other literature. The gesture type Pointing At
Location is composed of the operations Articulator Profiling (e.g., straight
extended arm, hand and index), Shape Profiling (the predominant axis, a line,
is profiled), Continuation (the line is continued, indicating a direction),
and Intersection (the line intersects with the surface of an object in a
point: the location pointed at). The gesture type Drawing—while otherwise
containing the same operations as Pointing At Location—requires adding the
operation of Trace Leaving (by moving the arm, and hence all the other forms
created by the above operations, the point leaves a trace in form of a line).
The geometrical operations of Gesture Form Analysis (and the constituent forms
specified in parentheses) consider specifically the spatial modality of
gesture, taking a first step towards a strictly form-based gesture semantics.
The systematic analysis of operations across gesture types results in a
gesture typology, in which the dimensions of all constituent forms are
defined; thus being open to computational application. The fundamental
theoretical distinction of gesture form being non-equivalent to the mere
physical form of the articulators (articulator form) is supported by an
object-description study in an optical motion-capture system. The methods
include operationalising three-dimensional gesture data, for example by a
plugin for the video-annotation software Elan.
