Designing Personalized User Experiences in eCommerce

How do you design personalized user experiences that delight and provide value to the customers of an eCommerce site? Personalization does not guarantee high quality user experience: a personalized user experience has the best chance of success if it is developed using a set of best practices in HCI. In this book 35 experts from academia, industry and government focus on issues in the design of personalized web sites. The topics range from the design and evaluation of user interfaces and tools to information architecture and computer programming related to commercial web sites. The book covers four main areas: -Theoretical, Conceptual, and Architectural Frameworks of Personalization, -Resear...

Qualitative HCI Research

Human-Computer Interaction (HCI) addresses problems of interaction design: understanding user needs to inform design, delivering novel designs that meet user needs, and evaluating new and existing designs to determine their success in meeting user needs. Qualitative methods have an essential role to play in this enterprise, particularly in understanding user needs and behaviours and evaluating situated use of technology. Qualitative methods allow HCI researchers to ask questions where the answers are more complex and interesting than "true" or "false," and may also be unexpected. In this lecture, we draw on the analogy of making a documentary film to discuss important issues in qualitative H...

Human-Computer Interaction – INTERACT 2005

We will be, sooner or later, not only handling personal computers but also mul- purpose cellular phones, complex personal digital assistants, devices that will be context-aware, and even wearable computers stitched to our clothes...we would like these personal systems to become transparent to the tasks they will be performing. In fact the best interface is an invisible one, one giving the user natural and fast access to the application he (or she) intends to be executed. The working group that organized this conference (the last of a long row!) tried to combine a powerful scientific program (with drastic refereeing) with an entertaining cultural program, so as to make your stay in Rome the m...

Personal Information Management

In an ideal world, everyone would always have the right information, in the right form, with the right context, right when they needed it. Unfortunately, we do not live in an ideal world. This book looks at how people in the real world currently manage to store and process the massive amounts of information that overload their senses and their systems, and discusses how tools can help bring these real information interactions closer to the ideal. Personal information management (PIM) is the study and practice of the activities people perform to acquire, organize, maintain, and retrieve information for everyday use. PIM is a growing area of interest as we all strive for better use of our limi...

Usage Policies for Decentralised Information Processing

Usage Policies for Decentralised Information Processing

Owners impose usage restrictions on their information, which can be based e.g. on privacy laws, copyright law or social conventions. Often, information is processed in complex constellations without central control. In this work, we introduce technologies to formally express usage restrictions in a machine-interpretable way as so-called policies that enable the creation of decentralised systems that provide, consume and process distributed information in compliance with their usage restrictions.

Multitasking in the Digital Age

Multitasking in the Digital Age

In our digital age we can communicate, access, create, and share an abundance of information effortlessly, rapidly, and nearly ubiquitously. The consequence of having so many choices is that they compete for our attention: we continually switch our attention between different types of information while doing different types of tasks--in other words, we multitask. The activity of information workers in particular is characterized by the continual switching of attention throughout the day. In this book, empirical work is presented, based on ethnographic and sensor data collection, which reveals how multitasking affects information workers' activities, mood, and stress in real work environments...

Usable Security

There has been roughly 15 years of research into approaches for aligning research in Human Computer Interaction with computer Security, more colloquially known as ``usable security.'' Although usability and security were once thought to be inherently antagonistic, today there is wide consensus that systems that are not usable will inevitably suffer security failures when they are deployed into the real world. Only by simultaneously addressing both usability and security concerns will we be able to build systems that are truly secure. This book presents the historical context of the work to date on usable security and privacy, creates a taxonomy for organizing that work, outlines current research objectives, presents lessons learned, and makes suggestions for future research.

Human-Computer Interactions in Museums

Human-Computer Interactions in Museums

Museums have been a domain of study and design intervention for Human-Computer Interaction (HCI) for several decades. However, while resources providing overviews on the key issues in the scholarship have been produced in the fields of museum and visitor studies, no such resource as yet existed within HCI. This book fills this gap and covers key issues regarding the study and design of HCIs in museums. Through an on-site focus, the book examines how digital interactive technologies impact and shape galleries, exhibitions, and their visitors. It consolidates the body of work in HCI conducted in the heritage field and integrates it with insights from related fields and from digital heritage pr...
