Philippe was most recently Director of User Experience Design for Yahoo!'s next generation digital advertising platform APT. Prior to that he co-founded, ran, and sold 995 SOFT, a leading publisher of consumer software for mobile devices. Prior to 995 SOFT, he was CTO and VP Engineering with Bertelsmann BeMusic, a provider of online music storage, streaming and subscription services. Before joining Bertelsmann, he was VP Product Development at Pagoo Communications, where he headed the design and implementation of Voice Over IP applications. In 1998, he co-founded Zowie Intertainment — a high-tech toy company — to commercialize the smart toy concept he developed at Paul Allen's Interval Research. Zowie's critically acclaimed products where heralded by Newsweek as "It toys of 1999" and the company was subsequently acquired by Lego Systems, Inc. He conducted his thesis research at Stanford University and earned his Ph.D. degree from Université Pierre et Marie Curie in Paris.

Cohen, Jonathan, Withgott, Meg and Piernot, Philippe (1999): Logjam: A Tangible Multi-Person Interface for Video Logging. In: Altom, Mark W. and Williams, Marian G. (eds.) Proceedings of the ACM CHI 99 Human Factors in Computing Systems Conference May 15-20, 1999, Pittsburgh, Pennsylvania. pp. 128-135. Available online

This paper describes the evolution, implementation, and use of logjam, a system for video logging. The system features a game-board that senses the location and identities of pieces placed upon it. The board is the interface that enables a group of people to log video footage together. We report on some of the surprising physical and social dynamics that we have observed in multi-person logging sessions using the system.

Rice, James, Farquhar, Adam, Piernot, Philippe and Gruber, Thomas (1996): Using the Web Instead of a Window System. In: Tauber, Michael J., Bellotti, Victoria, Jeffries, Robin, Mackinlay, Jock D. and Nielsen, Jakob (eds.) Proceedings of the ACM CHI 96 Human Factors in Computing Systems Conference April 14-18, 1996, Vancouver, Canada. pp. 103-110. Available online

We show how to deliver a sophisticated, yet intuitive, interactive application over the web using off-the-shelf web browsers as the interaction medium. This attracts a large user community, improves the rate of user acceptance, and avoids many of the pitfalls of software distribution. Web delivery imposes a novel set of constraints on user interface design. We outline the tradeoffs in this design space, motivate the choices necessary to deliver an application, and detail the lessons learned in the process. These issues are crucial because the growing popularity of the web guarantees that software delivery over the web will become ever more wide-spread.

Piernot, Philippe, Felciano, Ramon M., Stancel, Roby, Marshall, Jonathan and Yvon, Marc (1995): Designing the PenPal: Blending Hardware and Software in a User-Interface for Children. In: Katz, Irvin R., Mack, Robert L., Marks, Linn, Rosson, Mary Beth and Nielsen, Jakob (eds.) Proceedings of the ACM CHI 95 Human Factors in Computing Systems Conference May 7-11, 1995, Denver, Colorado. pp. 511-518. Available online

As part of the 1994 Apple Interface Design Competition, we designed and prototyped the PenPal, a portable communications device for children aged four to six. The PenPal enables children to learn by creating images and sending them across the Internet to a real audience of friends, classmates, and teachers. A built-in camera and microphone allow children to take pictures and add sounds or voice annotations. The pictures can be modified by plugging in different tools and sent through the Internet using the PenPal Dock. The limited symbolic reasoning and planning abilities, short attention span, and pre-literacy of children in this age range were taken into account in the PenPal design. The central design philosophy and main contribution of the project was to create a single interface based on continuity of action between hardware and software elements. The physical interface flows smoothly into the software interface, with a fuzzy boundary between the two. We discuss the design process and usability tests that went into designing the PenPal, and the insights that we gained from the project.

Piernot, Philippe and Yvon, Marc (1995): A Model for Incremental Construction of Command Trees. In: Kirby, M. A. R., Dix, Alan J. and Finlay, Janet E. (eds.) Proceedings of the Tenth Conference of the British Computer Society Human Computer Interaction Specialist Group - People and Computers X August, 1995, Huddersfield, UK. pp. 169-179.

Application histories have been used for a variety of purposes including error recovery, browsing past activities, macro recording and demonstrational interfaces. However, in most systems the history is kept as a simple list of primitive commands, which poorly reflects the user task structure. In this paper we first present Command Trees, a richer representation of command histories that offers better support for undo/redo mechanisms and programming by demonstration. We then introduce a new model to support incremental construction of command trees and an object-oriented application framework that implements this model. An important property of this model is that it is independent of the interaction modality, thus extending its purpose.

Yvon, Marc, Piernot, Philippe and Cot, Norbet (1995): Programming by Demonstration: Detect Repetitive Tasks in Telecom Services. In: Proceedings of OZCHI95, the CHISIG Annual Conference on Human-Computer Interaction 1995. pp. 68-74.

Telecommunication services are bundled together into single applications. These applications allow for connections to many servers and computers, for quick and reliable data access and for document exchange. The invoked tasks can be combined and complex, they may take place in several applications such as copying final data in spreadsheets or word processors using inter-application communication protocols. Users should perform these time consuming tasks only once and let the computer take care of repetitive tasks. Programming by demonstration is a solution to that issue, it empowers the telecommunication services by detecting repetitive sequences, automating them and learning about the users' working methodology.

My devil's dictionary definition for an Intelligent Agent is a query program with a user interface that is so obscure that you must anthropomorphize it in order to account for its behavior.
