The following tutorials will be held on April 20 in Vienna. Please note that the tutorials overlap with the workshop sessions, so registering to both is not possible.


T1: Radio Frequency Identification - April 20, 9:00-12:30

Christian Floerkemeier
Institute for Pervasive Computing
ETH Zurich

About the author:


Christian Floerkemeier holds a Ba and MEng degree from Cambridge University in the UK and is currently a research assistant in the group of Prof. Friedemann Mattern at the Institute for Pervasive Computing at ETH Zurich. As part of the industry sponsored research program M-Lab, he was involved in the design and implementation of various RFID based applications. He is also member of the research staff at the Auto-ID Lab in Switzerland. As author of the Auto-ID Center mark-up language PML Core, he has been involved in the standardization effort at the Auto-ID Center for the past two years.


Radio Frequency Identification (RFID) technology is rapidly evolving as a result of increased awareness of its potential in the business community, adoption by developers to bridge the gap between the physical and virtual world and the development of new manufacturing techniques that might allow for low-cost RFID tags.
RFID systems have been successfully used in specialized application domains such as cattle herding, library checkout, car immobilizers and ski ticketing. More recently, the technology has received increased attention as a technology that can provide better transparency and visibility in the supply chain.

Objectives and Outline

The purpose of this tutorial is to provide an overview of RFID systems and their various principles of operation, so that the participants get a better understanding of the challenges and
opportunities involved.

We pursue the objective to explain the operating principles of various available, passive RFID systems across the frequency range from low frequency (LF) to ultrahigh frequencies (UHF). In particular, we will show how the operating principles of RFID systems affect performance indicators such as read range and the
number of tags that can be detected per unit time. This discussion includes RFID system components, reader-transponder coupling and communication and anti-collision algorithms. We will also outline
current standardization efforts in the RFID domain. In particular, we will focus on ISO standards and the Auto-ID Center/EPCglobal standards.

Recent proposals by the research community address the privacy concerns that arise from a large scale deployment of RFID systems. It is our goal to show how, for example, blocker tags or hash-based access control works and to discuss their merits. Finally, future trends in RFID technology and novel application
domains are outlined. This includes recent developments at the Auto-ID Center/EPCglobal and the potential availability of low-cost RFID transponders.


The goal of this tutorial is to provide an overview of the rapidly evolving field of RFID technology. Along with the operating principles of various available systems, we will discuss the opportunities and challenges that arise from their use. Recently proposed approaches to address the privacy concerns associated
with large scale deployment of RFID systems are also presented.




T2: User Interface Design for Home Systems - April 20, 14:00 - 17:30

Martin Maguire
Loughborough University
Holywell Building, Holywell Way
Loughborough, Leicestershire LE11 3UZ

About the author:


Dr. Martin Maguire
Martin has a background in both computer studies and ergonomics. He works at the Ergonomics and Safety Research Institute (ESRI) at Loughborough University. His main interests are in the design of interactive systems, pervasive computing, and consumer products to be usable by the general public, including older and disabled people, along with the development of human factors tools, methods and guidelines in these areas. He is currently working on a project within The Application Home Initiative (TAHI) in the UK to establish the feasibility of bringing aggregated services into the home. Martin is a member of the UK Ergonomics Society, the ACM and is on the Council of the UK Usability Professionals Association.



In the future home, it will be possible for devices to be networked and centrally controlled and for services to be provided that can be aggregated together. This raises many issues that affect the end user such as the usability and acceptance of these services. The design of the user interface to support effective control of devices and access to services is therefore critical to the successful acceptance of the connected home concept.


What delegates will learn

  • The need to design the user interface in the knowledge of the home context and use of scenarios to establish the required functions and features.
  • Steps to perform in designing a user interface for a home product or system. Principles and guidelines when designing user interfaces for home systems such as the importance of establishing a clear structure that can be understood by a wide range of people.
  • Practice in creating a paper-based user interface mock-up and testing it with users.

Who should attend?
The session should be of interest to consumer product designers and designers in the area of home systems. It should also be relevant to project managers and marketers in the home systems sector, as well as students taking courses on IT, usability, and HCI (Human-Computer Interaction).


Each delegate will receive a booklet with a copy of the slides presented during the session, the exercise materials, and a set of relevant published papers.
