Title: Handwriting Stroke Trajectory Variability in the context of the
Kinematic Theory
prof. dr. Réjean Plamondon
Abstract
This presentation summarizes the basic properties of rapid
trajectories produced by human subjects and shows how the Kinematic
Theory, in its vectorial form, can explain the origin of all the
features generally observed in empirical studies dealing with the
control of rapid movements, such as strokes in handwriting.

CV of speaker
Rejéan Plamondon received the BSc degree in physics and the MScA and
PhD degrees in electrical engineering from the Universite Laval,
Quebec, Canada, in 1973, 1975, and 1978, respectively. In 1978, he
became a member of the faculty of the Ecole Polytechnique, Montreal,
Canada, where he is currently a full professor. He was the head of the
Department of Electrical and Computer Engineering from 1996 to 1998
and he is now the chief executive officer of the Ecole Polytechnique,
one of the largest engineering schools in Canada. Over the past 20
years, Dr. Plamondon has proposed many original solutions to problems
in the field of on-line and off-line handwriting analysis and
processing. He has based these solutions on his exhaustive studies of
human movement generation and perception, particularly as it relates
to problems associated with the design of automatic systems for
signature verification and handwriting recognition, and has also
applied this knowledge to the development of interactive electronic
penpads to help children learn handwriting skills and of powerful
methods for analyzing and interpreting neuromuscular signals. His
major contribution has been the theoretical development of a kinematic
theory of rapid human movements which can take into account, with the
help of a single equation called a delta-lognormal function, many
phenomena reported in empirical studies dealing with rapid movements
over the past century. The theory has been found to be successful in
describing the basic kinematic properties. His research interests
focus on the automatic processing of handwriting: neuromotor models of
movement generation and image perception, script recognition,
signature verification, signal analysis and processing, electronic
penpads, man-computer interfaces via handwriting, forensic sciences,
education, and artifical intelligence. He is the founder and director
of Laboratoire Scribens, a research group dedicated exclusively to the
study of these topics. Dr. Plamondon is an active member of several
professional societies; is the president of the International
Graphonomics Society; and is the Canadian representative on the Board
of Governors of the International Association for Pattern Recognition
(IAPR). From 1988 to 1994, he was the chair of the IEEE Computer
Society TC-11. In 1989-1990, he was a fellow at the Netherlands
Institute for Advanced Study in Wassenaar. From 1990 to 1997, he was
the president of the Canadian Image Processing and Pattern Recognition
Society. In 1994, he was named a fellow of the IAPR and, from 1994 to
1998, he was the chair of the IAPR conferences and meetings committee.
He is the author or coauthor of numerous publications and technical
reports. He has coedited four books and has also published a
children's book, a novel, and two collections of poems. He is a fellow
of the IEEE.
