Tutorials

After 11 years of Mobile HCI, providing an overview of the state of the art becomes more and more challenging. During the tutorial day, a number of well-known researchers in Mobile HCI give overviews of the state of the art and cover many of the relevant topics during the tutorial day. Each tutorial will be 1 hour and will address selected topics in detail. The lecturers will also introduce you to the “must read” papers in this domain. The expected audience is varied and includes new students starting a PhD in Mobile HCI, practitioners wanting a quick survey of the state of the art and educators wishing to get an overview of Mobile HCI for their own teaching.

Tutorials will be held on Tuesday, September 15th, 2009, from 9:00 – 17:30 in the Lecture Rooms of the University. The tutorial day registration fee is €80 for early registration (for students 30 €), and includes access to all the tutorials listed below, as well as coffee/tea and lunch during the breaks. If you wish to register for the tutorials, you should register for the conference as well.

Mobile Search

By Matt Jones, PhD (Slides)

Desktop search is the most popular interactive web-activity with billions of interactions daily. Mobile search is increasing in significance and this tutorial will review the state-of-the-art knowledge touching topics such as: user motivations for mobile search; query capture; and, search result visualisation and interaction. While we will of course consider query-result, screen-based mobile systems, the tutorial will also explore more adventurous visions for seeking and finding including those involving multimodal elements (such as audio and gestures) and social-network based schemes.

Information Visualization and Visual Interfaces for Mobile Devices

By Luca Chittaro, PhD (Slides)

Mobile devices have now powerful graphics capabilities that enable the creation of novel visual interfaces – based on 2D (or even 3D) graphics - to help users on the move in dealing more quickly and easily with larger amounts of information. This tutorial will introduce participants to what we can learn (and what we need to adapt) from the field of visualization to build effective visual interfaces on mobile devices. It will also briefly show how information visualization techniques are useful to create new tools for studying the behaviour of mobile users. No particular background in information visualization is required.

Mobile Guides

By Chris Kray, PhD (Slides)

Mobile guides are one of the most widely used location-based services, and are now being rolled out commercially on a large scale. Often, mobile guides are thought of as just being ‘maps with a few markers and a highlighted route’ but this is a very narrow perspective - they can be much more. This tutorial will provide a systematic overview over the large body of research in this area. Topics covered will include psychological foundations of way finding and producing directions, different means to convey route instructions through a mobile interface as well as ways to represent and deal with location.

Mobile Privacy

By Marc Langheinrich, PhD (Slides)

Mobile applications that go beyond simple GPS-enabled maps often involve significant privacy issues. This tutorial will first frame the problem associated with mobile applications and personal privacy, i.e., why should we care about privacy issues when designing mobile applications? It will then summarize the current state-of-the-art in location privacy, i.e., computational countermeasures, consumer attitudes, and legal realities. Last but not least, it will also try to offer a somewhat larger view of privacy in general: what is it, and why should we want it?

Mobile Interaction with the Real World

By Enrico Rukzio, PhD (Slides)

Over the last years, there has been an increasing interested in extending the interaction between users and mobile devices to the interaction with objects from the everyday world. For example, people can use their mobile phones to take pictures of visual markers and have their codes recognized. A further example is the usage of RFID/NFC that is gaining popularity as it can reduce payment, identification or access control by simply swiping a mobile phone over a reader. This tutorial will provided a systematic overview of such interaction techniques, will discuss different technologies that are used for their implementation and will discuss applications areas and upcoming trends.

Modelling and Developing Mobile Applications

By Paul Holleis, PhD (Slides)

The development of mobile, pervasive applications is still a difficult task. Although by now there have been introduced APIs and several studies explored many aspects of mobile interfaces and services, it is often a complex and time-consuming task to create mobile applications and evaluate their usability properties. In this tutorial we will see current research and results about how to use usability models for easily and automatically evaluating certain aspects of mobile interfaces. Concentrating on the time to completion of tasks, I present approaches of how to integrate such methods into the development process and thus remove some of the burden from the developer.
