mReplay Research

My research is primarily in wireless technologies (mobile computing and RFID), and technology policy, but has also including information organization and retrieval, human factors, multimedia information, networked information systems, and information policy and management. As part of SIMS Research, I am part of some of most influential academic centers of their field, such as SIMS' Center for Document Engineering , Garage Cinema Research , SIMS Econ Research , and co-affiliated Management of Technology Program , the Berkeley Center for Law & Technology , and the Samuelsons Law, Technology and Public Policy Clinic .

In this paper, I propose a economics "Rawlsian framework" to provide a balanced protection of privacy, while suggesting limits to how companies implement this efficient technology, so that both consumers and business can benefit from the significant improvements in organization, sorting, distribution and
cost savings that RFID technology could provide.


Riley, P. and E. Schubert. mReplay: Mobile Sports Replay and Fan Democracy, IEEE Press, Proceedings of the AXMEDIS, 2005.

Abstract: mReplay (short for “mobile replay”) is a solution to an intriguing problem: individuals attending sporting events have less information than those watching the same game on television, where commentators attempt to explain events and sometimes replay events repeatedly, showing the viewer a certain play. mReplay is an information system that provides on-demand instant sports replay functionality to most mobile devices, (for example non-3G mobile phones, PDAs, and even the new Sony PSP) including those mobile devices without video playback. mReplay also allows users to vote during the sporting event: for example, for their favorite play of the game, or on whether an officiating call was accurate, or for their favorite player, all from their mobile device.

Needs and Usability Assessment



Despite their growing numbers, elderly computer users are struggling with more usability barriers than ever before. Currently, I am researching elderly computer users in the Rossmoor Retirement Community and observing their interactions with a number of technologies' user interfaces and systems. Based on this research, I am designing an innovative prototype website (Compumoor) which provides optimal usability needs for children, elderly, disabled, and foriegn users. Comumoor media:

Center for Digital Technology & Management
Ludwig Maximilians Universität

I am lecturing at LMU/TU's CDTM program on the Social Consequences of Science and Technology.

Under the combined influences of technological progress, economic and political regulation, and social components, modern technological innovations are used by individuals of many different social backgrounds. Do social and cultural qualities contribute to technological innovation, or have they changed because of technological innovation? (For example, why did the old fashion, large front-wheel bicycle stay "modern" for so long? Why did it take society so long to appreciate and adapt to the modern day bicycle?) Our readings will briefly assess the history of science and technology development to consider this question and examine how definitions and expectations of technology and science differ among the relevant social groups and cultures.


SIMS 290 Section 1
Realizing Digital Convergence

University of California, Berkeley

Under Professor Yale Braunstein, I was the Teaching Assistant for this innovative course where lectures and project development were coordinated with a team from the LMU/TU in Munich, Germany. This course combined lectures on industry structure, market analysis, and business models with the development of a working prototype and business case for a multimedia application. The application was an innovative digital magazine that combined the possibilities of the Internet and mobile communications with traditional print content. See more here.

Information Organization
and Retrieval



Currently, we are designing applications that provide a means of creating, sharing, and reusing mobile media and metadata with a Nokia 3650 cell phone. I belong to an innovative group (Garage Cinema Research) that is designing an application called Recreation Evaluation Interface (REI) and Wishter. REI media:

I also was a part of a small team of user interface designers that designed the mobile phone UI and web UI for Wishter, which was presented to Nokia.




Currently, I am in Munich, Germany doing my Fulbright-sponsored research on RFID implementation and the social and economic effects of RFID use. In addition, I am contributing to research at TUM on Location Based Services and other mobile phone system design.
