Investigating Privacy Attitudes and Behavior in Relation to Personalization

Abstract: This article presents an experimental study of privacy-related attitudes and behaviors regarding a music recommender service based on two types of user modeling: personality traits and musical preferences. Contrary to prior expectations and attitudes reported by participants, personality traits are frequently disclosed to the system and other users, indicating that embedded modeling of user personality does not represent an acceptance barrier. Discrepancies between privacy attitudes and behaviors have been reported before in the context of e-commerce applications, but the corresponding studies could not exclude several conflicting hypotheses, such as participants expressing attitudes outside the context of specific privacy dilemmas and contact with researchers, which may have mitigated perceived privacy risks. Arguably, these are fundamental problems in empirical investigations into privacy that apply to most published works relating to privacy and user modeling. Measures to control these factors in this study are discussed, and methodological suggestions for future research are presented.

Moving Tangible Interaction Systems to the Next Level

Abstract: Understanding tangible interaction's foundational concepts can lead to systems with direct, integrated, and meaningful data control and representation

An analysis of input-output relations in interaction with smart tangible objects

Abstract: This article focuses on the conceptual relation between the user's input and a system's output in interaction with smart tangible objects. Understanding this input-output relation (IO relation) is a prerequisite for the design of meaningful interaction. A meaningful IO relation allows the user to know what to do with a system to achieve a certain goal and to evaluate the outcome. The work discussed in this article followed a design research process in which four concepts were developed and prototyped. An evaluation was performed using these prototypes to investigate the effect of highly different IO relations on the user's understanding of the interaction. The evaluation revealed two types of IO relations differing in functionality and the number of mappings between the user and system actions. These two types of relations are described by two IO models that provide an overview of these mappings. Furthermore, they illustrate the role of the user and the influence of the system in the process of understanding the interaction. The analysis of the two types of IO models illustrates the value of understanding IO relations for the design of smart tangible objects.

The sensitivities of user profile information in music recommender systems

Abstract: Personalized services can cause privacy concerns, due to the acquisition, storage and application of sensitive personal information. This paper describes empirical research into the factors influencing the trade-off between the perceived benefits of personalization and the privacy ‘costs’ experienced by individuals. The experiment in question concerns a music recommender system accessed over the Internet. Recommendations are based on two different types of information about their user: music preferences and personality. Users are offered several levels of disclosure for this information. Results show similar disclosure behavior by the users for the two types of personal information. This contradicts attitudes of users as they were reported in a questionnaire and post-experiment interview. Factors that influence people’s disclosure behavior are the amount and clarity of information regarding the purpose of the information disclosure and regarding who gets access to the information, the degree of confidentiality of the information involved and the benefits people expect to gain from disclosing personal information.

On the relative importance of privacy guidelines for ambient health care

Abstract: We present an empirical study regarding the relative importance of complying with privacy related guidelines in the context of a Health Monitoring System. Participants were confronted with text scenarios describing privacy related aspects of a health monitoring service for daily use at home. Participants assessed the relative importance to them of simplified variants of the OECD (Organization of Economic Cooperation and Development) guidelines for the protection of personal data. The guidelines that relate to Insight and Openness were most valued. The guidelines relating to Modification and Data Quality were valued least by most participants in this context. Methodological challenges were encountered on the way, which reveal the complexity of conducting empirical investigations of privacy aspects of human-computer interaction.

The Dictionary of Philosophy

Abstract: THIS is a single volume, easy to handle and read, containing explanations of philosophical terms and outline accounts of schools of thought, special subjects and individual thinkers. It looks as though the efforts of a number of specialists had been put together in alphabetical order with little editing. Many of the articles are just right; for example, that on ‘Hegelianism’, and most of the definitions of Aristotelian terms. A few articles are too brief for clarity; many are too long and try to do too much. The Dictionary of Philosophy Edited by Dagobert D. Runes. Pp. viii + 343.

The nature of research.

Abstract: 88 remarks that each researcher is a “detective at the scene of a crime looking for the clues” that nature freely—but maybe not so readily— provides when the correct questions are asked and the appropriate facilities are available. Sometimes previous experiments by other scientists may have already provided the sought-for answers, but a researcher must be aware of these results and trust them. If the “alleged facts ... seem to be nonsense,” they may be, notes Webb; alternatively, another researcher may not understand the results. In some subjects, like high-energy physics, researchers watch a game played before them, and their task as researchers is to deduce the contest’s rules, learning how things operate so that the principles can be extrapolated to new situations. By contrast, in observational sciences like astronomy or geology, researchers are presented with the contest’s outcome, from which they must try to derive the rules (or break the code). Knowing how the universe has evolved, these scientists seek ultimately to infer the starting conditions that lead to the world in which we live today. Over the last half century, the science of biology has, at an accelerating pace, moved away from mere cataloging to studying processes with the most modern tools of the physical sciences and technology. Current wisdom is that the majority of this generation’s scientific breakthroughs will happen in the life sciences.
