PHILIPS RESEARCH, PENAC, Briarcliff Manor, NY 1986 - 2002

Senior Human-Computer Interaction Researcher in various groups

1998 - 2001


Led projects in “group videoconferencing”: built in C++ an "automatic cameraman" and an "automatic producer", based on computer vision analysis (people and motion detection) and audio direction detection. They involved several prototypes, heuristics, and observation of actual use; resulted in a CHI2001 conference paper. High interest by product division. 2001


Led project in "ambient intelligence" (pervasive computing): defined scenarios & practical applications for Philips demo-house; analyzed possibilities, requirements and context questions for computer vision in an intelligent house; co-author of a NIST-ATP proposal “Elderly Care Monitoring” (via computer vision); experimented with a User Interface for a light spot remote control device.



Led project in "electronic companions": explored the notion of a TV set as a companion; proposed devices that would act as companions to elderly. Mock-ups; focus group sessions with elderly; many patent applications. Studied personality and conversation. Cultivated relationship with CSLI (Center for Study of Language and Information, Stanford University) for application of their "Media Equation." 1997


Wrote position paper on performance analysis for computer vision algorithms. 1995-1997


Member of "remote collaborative learning" project: focused the project towards realistic, visible and user-centered deliverables. Responsible for analysis of student and teacher requirements via experimental setups at the University of Pittsburgh (Prof. Mahling) in the context of “Problem Based Learning” sessions. 1995 - 1996


Member of global Philips User Interface (UI) steering group aimed at incorporating UI into research projects and defining a Philips strategy for UI research. Benchmarked UI strategies in Far-East companies and in Silicon Valley. 1986 - 1994


Led the development of a novel on-screen UI style for consumers, based on multimedia. Designed and prototyped various consumer systems and their UIs; performed task analysis, user tests and market research; promoted them within Philips (with demos and videotapes); pursued their commercialization.


The systems are:


An electronic TV guide system and interactive TV services. 3 patents awarded on its usage of an

interest profile of the consumer. Also led the effort of analyzing its business potential and contacting potential partner companies, in particular in the digital cable environment.


A variety of TV control systems (e.g. Picture-in-Picture) while starting up a team working for the

MAGNAVOX product division.


An integrated TV-VCR system, featuring automatic recording and replay of favorite programs, and tape space allocation. Very enthusiastic reaction by focus group participants.


PRIME COMPUTER, INC, Framingham, MA 1980-1985

Senior Technical Consultant


In operating system group, worked on a Virtual Memory File Access system.


In advanced development group, invented a novel architecture for application programs with a graphical and responsive user interface; prototyped the approach and published it. Based on this, participated in the landmark SEEHEIM User Interface Management Systems (UIMS) workshop.


In workstation architecture group, designed and prototyped a UI code generator, and an environment that integrates a PRIME PC with a PRIME host computer


CICESE (Centro de Investigación Científica y de Educación Superior de Ensenada), Baja California, Mexico 1978-1979

Computer Science Researcher / Graduate Teacher


Responsibilities included research around the software of the newly acquired PRIME computers and developing / teaching graduate level courses about it (Operating System, Assembler, Networking, etc.). Supervision of thesis students. Built up CICESE to one of the leading centers with PRIME expertise in both Californias.

Scientific Programmer


Responsible for all "Formula Manipulation" needs of the local theoretical physicists (incl. 1999 Physics Nobel Laureates Veltman and 't Hooft) via the SCHOONSCHIP system. Also collaborating with them on actual symbolic calculations. Developed algorithms and wrote manuals for SCHOONSCHIP. Converted it (25K lines of CDC 7000 assembler) to IBM using a PL/1-like compiler to obtain a portable macro implementation. Responsible for the worldwide maintenance of SCHOONSCHIP and lectured extensively on its capabilities thus increasing its usage more than tenfold.
