Instrumented Usability Analysis for Mobile Devices BIBAFull-Text 1-19
  Andrew Crossan; Roderick Murray-Smith; Stephen Brewster; Bojan Musizza
Instrumented usability analysis involves the use of sensors during a usability study which provide observations from which the evaluator can infer details of the context of use, specific activities or disturbances. This is particularly useful for the evaluation of mobile and wearable devices, which are currently difficult to test realistically without constraining users in unnatural ways. To illustrate the benefits of such an approach, we present a study of touch-screen selection of on-screen targets, whilst walking and sitting, using a PocketPC instrumented with an accelerometer. From the accelerometer data the user's gait behaviour is inferred, allowing us to link performance to gait phase angle, showing there were phase regions with significantly lower error and variability. The article provides examples of how information acquired via sensors gives us quantitatively measurable information about the detailed interactions taking place when mobile, allowing designers to test and revise design decisions, based on realistic user activity.
Appropriating Heuristic Evaluation for Mobile Computing BIBAFull-Text 20-41
  E. Bertini; T. Catarci; A. Dix; S. Gabrielli; S. Kimani; G. Santucci
Heuristic evaluation has proven popular for desktop and web interfaces, both in practical design and as a research topic. Compared to full user studies, heuristic evaluation can be highly cost-effective, allowing a large proportion of usability flaws to be detected ahead of full development with limited resource investment. Mobile computing shares many usability issues with more conventional interfaces. However, it also poses particular problems for usability evaluation related to aspects such as limited screen real estate, intermittent user attention, and contextual factors. This article describes a modified collection of usability heuristics that are designed to be appropriate for evaluation in mobile computing. They have been systematically derived from extensive literature and empirically validated. They therefore offer a sound basis for heuristic-based evaluation in mobile computing. Besides introducing the reader to the practical use of heuristic evaluation, the article also closes with a description of potential future research in the area.
Pickup Usability Dominates: A Brief History of Mobile Text Entry Research and Adoption BIBAFull-Text 42-59
  Mark Dunlop; Michelle Masters
Text entry on mobile devices (e.g. phones and PDAs) has been a research challenge since devices shrank below laptop size: mobile devices are simply too small to have a traditional full-size keyboard. There has been a profusion of research into text entry techniques for smaller keyboards and touch screens: some of which have become mainstream, while others have not lived up to early expectations. As the mobile phone industry moves to mainstream touch screen interaction we will review the range of input techniques for mobiles, together with evaluations that have taken place to assess their validity: from theoretical modelling through to formal usability experiments. We also report initial results on iPhone text entry speed.
On-the-Move and in Your Car: An Overview of HCI Issues for In-Car Computing BIBAFull-Text 60-78
  G. E. Burnett
The introduction of computing and communications technologies within cars raises a range of novel human-computer interaction (HCI) issues. In particular, it is critical to understand how user-interfaces within cars can best be designed to account for the severe physical, perceptual and cognitive constraints placed on users by the driving context. This article introduces the driving situation and explains the range of computing systems being introduced within cars and their associated user-interfaces. The overall human-focused factors that designers must consider for this technology are raised. Furthermore, the range of methods (e.g. use of simulators, instrumented vehicles) available to designers of in-car user-interfaces are compared and contrasted. Specific guidance for one key system, vehicle navigation, is provided in a case study discussion. To conclude, overall trends in the development of in-car user-interfaces are discussed and the research challenges are raised.
User Acceptance of Mobile Services BIBAFull-Text 79-97
  Eija Kaasinen
Personal mobile devices are increasingly being used as platforms for interactive services. Ease of use is important, but the services should also provide clear value to the user and they should be trustworthy and easy to adopt. These user acceptance factors form the core of the Technology Acceptance Model for Mobile Services introduced in this article. The model has been set up based on field trials of several mobile services with altogether more than 200 test users. This article presents the technology acceptance model and introduces two case studies of implementing the model as a design and evaluation framework in practice.

Experiences of Supporting Local and Remote Mobile Phone Interaction in Situated Public Display Deployments BIBAFull-Text 1-21
  Jörg Müller; Keith Cheverst; Dan Fitton; Nick Taylor; Oliver Paczkowski; Antonio Krüger
Public displays and mobile phones are ubiquitous technologies that are already weaving themselves into the everyday life of urban citizens. The combination of the two enables new and novel possibilities, such as interaction with displays that are not physically accessible, extending screen real estate for mobile phones or transferring user content to and from public displays. However, current usability evaluations of prototype systems have explored only a small part of this design space, as usage of such systems is deeply embedded in and dependent on social and everyday context. In order to investigate issues surrounding appropriation and real use in social context field studies are necessary. In this paper we present our experiences with field deployments in a continuum between exploratory prototypes and technology probes. We present benefits and drawbacks of different evaluation methods, and provide a number of validated lessons from our deployments.
Embrace the Chaos, It's Not Noise: Lessons Learned from Non-Traditional Environments BIBAFull-Text 22-36
  Anthony Glascock; David Kutzik
The lessons learned from seven years of the testing of a behavioral monitoring system -- the Everyday Living Monitoring System (ELMS) -- outside the laboratory in the real world are discussed. Initially, the real world was perceived as messy and filled with noise that just delayed and complicated the testing and development of the system. However, over time, it became clear that without embracing the chaos of the world and listening very carefully to its noise, the monitoring system could not be successfully moved from the laboratory to the real world. Specific lessons learned at each stage of development and testing are discussed, as well as the challenges that are associated with the actual commercialization of the system.
Adapting Evaluation to Study Behaviour in Context BIBAFull-Text 37-55
  Scott Sherwood; Stuart Reeves; Julie Maitland; Alistair Morrison; Matthew Chalmers
We present a reflection on a series of studies of ubiquitous computing systems in which the process of evaluation evolved over time to account for the increasing difficulties inherent in assessing systems 'in the wild'. Ubiquitous systems are typically designed to be embedded in users' everyday lives; however, without knowing the ways in which people will appropriate the systems for use, it is often infeasible to identify a predetermined set of evaluation criteria that will capture the process of integration and appropriation. Based on our experiences, which became successively more distributed in time and space, we suggest that evaluation should become adaptive in order to more effectively study the emergent uses of ubiquitous computing systems over time.
User Evaluation of Mobile Devices: In-Situ versus Laboratory Experiments BIBAFull-Text 56-71
  Francis Jambon
Nowadays, mobile devices features are often linked up to the context of usage. As a consequence, researchers must consider not only the user and the device, but also the surrounding environment when designing effective user study evaluations. Two opposite experimental setups are possible: in-situ and in the laboratory. There is no consensus on their respective benefits, for instance with regard to the number of usability issues detected. In this paper, we isolate independent variables that could contribute to evaluation biases by proposing a taxonomy that splits the in-situ experimental setups into two new setups. We describe the concept of the "Uncertainty Principle" to emphasize the dilemma between precise observation and bias minimization and introduce the "Trojan Horse" technique to partially overcome the consequences of the uncertainty principle. As a conclusion, a methodology using both laboratory and in-situ experiments in a complementary way is proposed.

What does Mobile Mean? BIBAFull-Text 1-8
  Russell Beale
This article presents a perspective on what it really means to be mobile -- why being mobile is different. It looks at the technological and physical implications, but really considers the broader issues: the social implications, the impact that data on the move can have on people, and the use of mobile devices as sensors that can drive intelligent, contextual systems that provide a much more effective experience for the user than existing systems do.
Getting Connected: At What Cost? Some Ethical Issues in Mobile HCI BIBAFull-Text 9-17
  Antti Pirhonen; Elizabeth Sillence
The large scale deployment of mobile applications inevitably impacts upon our culture as a whole and affects more intimately our daily lives. Not all of these effects are desirable. In a market economy, ethical issues are not the most important drivers in the development of technology. In this article, we ask whether the mobile human-computer interaction community could take an active role in discussing ethical issues. In so doing we could focus our attention on developing technology for 'human beings' rather than fine tuning our emerging gadgets.
Empowering People Rather Than Connecting Them BIBAFull-Text 18-28
  Roderick Murray-Smith
This article discusses the consequences for the fundamentals of interaction design given the introduction of mobile devices with increased sensing capability. Location-aware systems are discussed as one example of the possibilities. The article provides eight challenges to the mobile HCI research community, and makes suggestions for how the International Journal of Mobile HCI could contribute to the field.
Mobile Internet: Past, Present, and the Future BIBAFull-Text 29-45
  Anne Kaikkonen
The Mobile Internet is no longer a new phenomenon; the first mobile devices supporting Web access were introduced over 10 years ago. During the past 10 years many user studies have been conducted that have generated insights into mobile Internet use. The number of mobile Internet users has increased and the focus of the studies has switched from the user interface to user experiences. Mobile phones are regarded as personal devices: the current possibility of gathering more contextual information and linking that to the Internet creates totally new challenges for user experience and design.
Mobile HCI: Thinking Beyond the Screen-Keyboard-Mouse Interaction Paradigm BIBAFull-Text 46-60
  Gitte Lindgaard; Sheila Narasimhan
In this position article we argue that it is time for the mobile HCI community to think beyond the traditional screen-keyboard-mouse paradigm and explore the many possibilities that mobility, mobile platforms, and people on the move offer. We present a collection of ideas aiming to encourage HCI researchers to explore how up-and-coming mobile technologies can inspire new interaction models, alternative I/O methods, and data collection methods. The range of possible applications designed to make life easier for specified user populations is limited, we maintain, only by our imagination to understand novel problem spaces, to mix, match and expand on existing methods as well as to invent, test, and validate new methods. We present several case studies in an attempt to demonstrate such possibilities for future mobile HCI.
Designing Mobile Phones for Children -- Is there a Difference? BIBAFull-Text 61-74
  Janet Read
The mobile phone is one of the most ubiquitous technologies in the developed world. In a market dominated by adults and older teenagers, one group of users that is relatively new to the mobile phone market is children. When children use mobile phones their needs are sometimes complicated by, or conflict with, the needs of their parents or primary care givers. As the laptop is being redesigned to make it accessible to children, it is worthwhile to ask the question 'Do children need a different sort of mobile phone than their parents?' By considering data about the use and usage of mobile phones, research on designing special children's technologies, and research on the needs of children as mobile phone users, this paper presents the argument that the mobile phone needs a design re-think if it is to meet the needs of children.
SatNav or SatNag? A Case Study Analysis of Evolving HCI Issues for In-Car Computing BIBAFull-Text 75-85
  G. E. Burnett
A wide range of in-car computing systems are either already in existence or under development which aim to improve the safety, efficiency and the comfort/pleasure of the driving experience. Several unique forces act on the design process for this technology which must be understood by HCI researchers. In particular, this is an area in which safety concerns dominate perspectives. In this position paper, I have used a case study system (vehicle navigation) to illustrate the evolution of some key HCI design issues that have arisen in the last twenty years as this in-car technology has matured. Fundamentally, I argue that, whilst HCI research has had an influence on current designs for vehicle navigation systems; this has not always been in a wholly positive direction. Future research must take a holistic viewpoint and consider the full range of impacts that in-car computing systems can have on the driving task.
Paper Rejected (p>0.05): An Introduction to the Debate on Appropriateness of Null-Hypothesis Testing BIBAFull-Text 86-93
  Mark. Dunlop; Mark Baillie
Null-hypothesis statistical testing has been seriously criticized in other domains, to the extent of some advocating a complete ban on publishing p-values. This short position article aims to introduce the argument to the mobile-HCI research community, who make extensive use of the controversial testing methods.

How It Started: Mobile Internet Devices of the Previous Millennium BIBAFull-Text 1-3
  Evan Koblentz
Internet access on cellular phones, after emerging as a new technology in the mid-1990s, is now a thriving activity despite the global economic recession. IDC reported smartphone sales of 1.18 billion units in 2008 (IDC, 2009), compared to the unconnected personal digital assistants approaching merely 1 million units per quarter in the second half of 2003.However, the concept of using handheld devices for wide area data applications began 25 years prior to the beginning of the end of PDAs.
User Experience of Mobile Internet: Analysis and Recommendations BIBAFull-Text 4-23
  Eija Kaasinen; Virpi Roto; Kristin Roloff; Kaisa Väänänen-Vainio-Mattila; Teija Vainio
Mobile access to the Internet with handheld devices has been technically possible for quite a while and consumers are aware of the services but not so ready to use them. A central reason for the low usage is that user experience of the mobile Internet is not yet sufficiently good. This paper analyses the mobile Internet from the end-user perspective, identifying factors and solutions that would make Internet usage on a mobile device an enjoyable experience. User experience can be improved by a better understanding of users and usage contexts, by developing mobile services that better serve the needs of mobile users, easing service discovery and by developing the infrastructure needed for the mobile Internet. This paper discusses all these aspects and gives development recommendations. Multidisciplinary and multicultural cooperation between the various actors in the field is needed to improve user experience.
Always On: A Framework for Understanding Personal Mobile Web Motivations, Behaviors, and Contexts of Use BIBAFull-Text 24-41
  Carol Taylor; Nancy Samuels; Judith Ramey
Mobile data services offer a growing alternative means of accessing the Web and have drawn significant attention from the mobile industry. However, design efforts are hampered people's motivations, behaviors, and contexts of use when they access the Web on their phones. To help address this need, we conducted a study to explore the following questions for U.S. mobile phone users: 1) What motivations lead people to access the Web on their mobile phones?; 2) What do they do?; and 3) Where do they do it? Based on the findings from Part One of the study, we constructed a taxonomy of behaviors, motivations, and contexts associated with mobile Web usage. In Parts Two and Three, we validated the taxonomy as well as compared iPhone versus non-iPhone user behaviors. We conclude this report by considering the design implications of our findings and future research directions.
Improving the User Experience of a Mobile Photo Gallery by Supporting Social Interaction BIBAFull-Text 42-57
  Elina Vartiainen
Today, image gallery applications on mobile devices tend to be stand-alone and offline. For people who want to share photos with others, many add-on tools have been developed to connect the gallery applications to Internet services to enable photo-sharing. The authors argue that photo-centric social interaction is best supported when the gallery application is fully integrated with an Internet service. In this case, no additional tools are needed and the user's image content is fully synchronized with the service. They designed and implemented a service-integrated mobile gallery application with a corresponding Internet service. Moreover, they conducted a field study with 10 participants to compare our application with a state-of-the-art gallery application combined with an add-on photo-sharing tool. Their application was preferred by most participants and it was especially appreciated because of the user experience. Above all, the results show that social activity increased amongst the participants while using our application.
Touch-Based Access to Mobile Internet: User Experience Findings BIBAFull-Text 58-79
  Minna Isomursu; Mari Ervasti
This article reports user experience findings from two field trials where Mobile Internet access was supported through Near Field Communication (NFC)-based tag infrastructure. The authors' results show that touch-based interaction can provide enhancement to the Mobile Internet user experience in: (1) content and service discovery, (2) Mobile Internet access, and (3) integrated situated and embodied experience. The problems related to service discovery can be solved by providing location-based access, and by using visual cues embedded into the environment for discovering content and services. Mobile Internet access through touch solves the problem of memorizing complicated URLs and the challenge of typing with a mobile device keypad. As touch-based access builds a semantic bridge between the physical context of use and the Mobile Internet experience, the user experience converges seamlessly into one where both the physical and digital worlds play a role.
