AFDE Symposium - 2010
AFDE's annual symposiums meet the challenge of providing continuing education, allowing document examiners to keep informed of the latest developments and research within the field, and to expand their knowledge in general or specific directions. The Association's motto is: Professionals who share knowledge increase their own skills.
The 2010 Symposium will be held October 14-17, 2010 in the Phoenix/Scottsdale area. You can sign up for emailed updates, or check back here to download the most current files (posted 5/20/10):

This workshop focuses on the properties of simulation behaviour in terms of models of motor control and the between simulator differences in simulation strategy as referenced through movement outcome. The objective of the workshop is to provide participants with an insight into the feasibility of common authorship opinions on multiple simulations by different writers. The workshop is comprised of a theoretical component and a large number of blinded practical exercises designed to develop, reinforce and test intersimulation common authorship determinations by participating FHEs
What Can Static Handwriting Features Reveal About Movement Dynamics?

In this presentation, we will explain how shape features from scanned signature images can be used to draw inferences on the movement dynamics. In a practical demonstration, MovAlyzeR software will be used to extract static and dynamic information from a scanned signature image that can be compared to exemplars collected online from suspects.
In a second study, we will show how electronic signature capture affects signatures due to the unusual stylus and stylus friction, size of the digital pad, unusual writing posture, and limited pad resolution. These issues can present challenges to FDEs when comparing electronic or point-of-sale signatures with conventional ink signatures. Case examples will be discussed.
