1. Using eye tracking to study mobile interfaces

In this tutorial we aim to give an introduction into how eye tracking works, how it can be used when studying interfaces on mobile devices such as mobile phones and what the limitations are. In the tutorial four different hardware setups that can be used when studying eye movements during interaction with mobile devices will be introduced. We will talk about the data you get from doing an eye tracking study, what to consider when choosing setup, but also give some general pointers on what to think about when doing eye tracking studies with mobile devices.

2. Personal Projectors for Mobile Human Computer Interaction

Projectors are a flexible medium for large, scalable and transitory display. They are pervasive as presentation infrastructure, widely deployed for public viewing, and increasingly replacing large screens in the home. Beyond display, projectors facilitate augmentation of real-world objects with visual overlay, and in combination with camera systems give rise to new forms of user interface from interactive surfaces to "everywhere" interfaces. Due to size, projectors have developed as infrastructure device, typically permanently installed, or set up ad hoc in a fixed position. However, miniaturization has now led to a first generation of devices, referred to as pico projectors, which are small enough to be used in truly mobile fashion - as handheld or wearable device, standalone or integrated with other personal devices. As a mobile personal device, pico projectors will be used in very different ways from projectors as we know them - just consider how different the use of handheld and wearable computers is from the use of PCs. In tutorial, I will survey current research on mobile personal projectors (including projector phones) to give the participants an understanding how pico projector technology is embraced for mobile human computer interaction. The participants will receive a comprehensive overview on developments from a conceptual perspective - analysing personal projector concepts, the input and output space for interaction with projectors, and sensing challenges and emerging applications in the mobile HCI context.

3. Performance evaluation of mobile services: measurements-based methodology and example assessment techniques

This tutorial first presents a generic methodology for measurements-based performance evaluation of a mobile communication system and its service(s), and second, it presents an application of this methodology to mobile healthcare services. The performance evaluation aims at analysis of, for example, mobile system bottleneck or scalability characteristics or at analysis of its responsiveness, where all metrics contribute to the overall experience of the mobile service use. The presented methodology has been derived from previous studies on performance of communication networks [1]. The methodology is outlined to perform (practical) measurements, as opposite to (theoretical) simulations or modeling. The methodology includes detailed steps for objectives determination, system instrumentation, and measurements execution and performance evaluation activities. The tutorial illustrates use of the methodology for performance evaluation of MobiHealth system and its vital sign tele-monitoring service provided to a mobile patient wearing a Wireless Body Area Network.

4. Speech Based Interaction: The Myths, Challenges, and Opportunities

HCI research has for long been dedicated to better and more naturally facilitating information transfer between humans and machines. Unfortunately, humans' most natural form of communication, speech, is also one of the most difficult modalities to be understood by machines - despite, and perhaps, because it is the highest-bandwidth communication channel we possess. While significant research efforts, from engineering, to linguistic, and to cognitive sciences, have been spent on improving machines' ability to understand speech, the MobileHCI community has been relatively timid in embracing this modality as a central focus of research. This can be attributed in part to the relatively discouraging levels of accuracy in understanding speech, in contrast with often-unfounded claims of success from industry, but also to the intrinsic difficulty of designing and especially evaluating speech and natural language interfaces. The goal of this course is to inform the MobileHCI community of the current state of speech and natural language research, to dispel some of the myths surrounding speech-based interaction, as well as to provide an opportunity for researchers and practitioners to learn more about how speech recognition works, what are its limitations, and how it could be used to enhance current interaction paradigms.

6. How to do Mobile HCI Research in the large

Since the introduction of application stores for mobile devices there has been an increasing interest to use this distribution platform to collect user feedback. Mobile application stores can make research prototypes widely available and enable to conduct user studies "in the wild" with participants from all over the world. Using apps as an apparatus goes beyond just distributing research prototypes. Consider apps as a tool for research means distributing specifically designed prototypes in order to extend our understanding of mobile HCI. In this tutorial we will provide an overview about recent research in this domain. It will be shown that stringent tasks and users´ motivation are crucial aspects. We will discuss how to design app-based experiments, what kind of users one can expect, and how to avoid ethical and legal issues.
