Modeling the Dynamics of Hair Movement

"What do you see in television commercials for hair products?" Anthony Gallium, of L'Oréal Recherche, posed to attendees during the IFSCC Congress in Paris. "Women turning their heads as their shiny, soft hair swings or cascades in slow motion." The dynamics of hair movement are of particular interest to product developers because they are important to consumers—who judge products based on the way they make their hair move. Cosmetic ingredient suppliers also have been focused on hair dynamics such as friction and how it impacts movement, as well as studied the flexibility of ingredient films to positively impact such movement.

In relation, computer animation and 3D modeling expert Norman Badler, PhD, of the University of Pennsylvania, will discuss ways to model the dynamics of hair movement during the Cosmetics & Toiletries Summit, to be held June 22 and 23, 2015, at the University of Pennsylvania in Philadelphia. In addition, he will attempt to calculate how coatings and other forces may impact the dynamics of hair movement.

Badler Biography

Norman I. Badler, PhD, is the Rachleff Professor of Computer and Information Science at the University of Pennsylvania (U Penn). Active in computer graphics since 1968 with more than 200 technical papers, his research involves developing software to acquire, simulate, animate and control 3D computer graphics human body, face, gesture, locomotion and manual task motions, both individually and for heterogeneous groups. Badler received his BA in Creative Studies Mathematics from the University of California at Santa Barbara in 1970. He also received his MSc in Mathematics in 1971 and PhD in Computer Science in 1975, both from the University of Toronto. He was the Cecilia Fitler Moore Department Chair of Computer and Information Science from 1990-1994, and he directs the the Susquehanna International Group (SIG) Center for Computer Graphics and the Center for Human Modeling and Simulation at U Penn.

Among the Center's achievements is the technology transfer, in 1996, of the human modeling software system Jack. Now an integrated product, and marketed by Siemens, it is used worldwide for human factors and ergonomics analyses of workplace and vehicle environments. Badler is the director of the BSE in Digital Media Design undergraduate program and the co-director of the masters in Computer Graphics and Game Technology program at U Penn. From 2001-2005, he also was the associate dean of the School of Engineering and Applied Science.

About C&T Summit

The C&T Summit is an interactive two-day event, designed to spark innovation and inspire the creative utilization of science in cosmetic product development. It will be held June 22 and 23, 2015, at the University of Pennsylvania in Philadelphia. Featuring a high-level technical conference and hands-on, practical application workshops, the C&T Summit provides an experiential learning environment, aiming to transfer knowledge through participation.
