Alarms, alerts, and other binary cues affect user behavior in complex ways. One relevant distinction is the suggestion that there are two different responses to alerts -- compliance (the tendency to perform an action cued by the alert) and reliance (the tendency to refrain from actions as long as no alert is issued). An experiment tested the dependence of the two behaviors on the Positive and Negative Predictive Values of the alerts (PPV and NPV) to determine whether these are indeed two different behaviors. Results suggest that the compliance is relatively stable and unaffected by irrelevant information (the NPV), while reliance is also affected by the PPV. The results are discussed in terms of multiple-process theories of trust in information sources.

Hafner, Verena, Lohse, Manja, Meyer, Joachim, Nagai, Yukie and Wrede, Britta (2011): The role of expectations in intuitive human-robot interaction. In: Proceedings of the 6th International Conference on Human Robot Interaction 2011. pp. 7-8.
Human interaction is highly intuitive: we infer reactions of our opponents mainly from what we have learned in years of experience and often assume that other people have the same knowledge about certain situations, abilities, and expectations as we do. In human-robot interaction (HRI) we cannot take for granted that this is equally true since HRI is asymmetrical. In other words, robots have different abilities, knowledge, and expectations than humans. They need to react appropriately to human expectations and behaviour. With this respect, scientific advances have been made to date for applications in entertainment and service robotics that largely depend on intuitive interaction. However, HRI today is often still unnatural, slow, and unsatisfactory for the human interlocutor. Both the sensorimotor interaction with environment and interlocutor, and the social aspects of the interaction still need to be researched and improved. Therefore, this full-day workshop aims to bring together researchers from different scientific fields to discuss these crosscutting issues and to exchange views on what are the preconditions and principles of intuitive interaction.

Ben-Asher, Noam, Kirschnick, Niklas, Sieger, Hanul, Meyer, Joachim, Ben-Oved, Asaf and Möller, Sebastian (2011): On the need for different security methods on mobile phones. In: Proceedings of 13th Conference on Human-computer interaction with mobile devices and services 2011. pp. 465-473.
Mobile phones are rapidly becoming small-size general purpose computers, so-called smartphones. However, applications and data stored on mobile phones are less protected from unauthorized access than on most desktop and mobile computers. This paper presents a survey on users' security needs, awareness and concerns in the context of mobile phones. It also evaluates acceptance and perceived protection of existing and novel authentication methods. The responses from 465 participants reveal that users are interested in increased security and data protection. The current protection by using PIN (Personal Identification Number) is perceived as neither adequate nor convenient in all cases. The sensitivity of data stored on the devices varies depending on the data type and the context of use, asking for the need for another level of protection. According to these findings, a two-level security model for mobile phones is proposed. The model provides differential data and service protection by utilizing existing capabilities of a mobile phone for authenticating users.

Personalizing news content requires to choose the appropriate depth of personalization and to assess the extent to which readers' explicit expressions of interest in general and specific news topics can be used as the basis for personalization. A preliminary survey examined 117 respondents' attitudes towards news content personalization and their interest in various news topics and subtopics. The second survey examined 23 participants' declared and actual interests. Participants preferred personalization based on general news topics. Declared interest in general news topics adequately predicted the actual interests in some topics, while in others users' interests differed between general news topics and subtopics. The variance in interest in items also differed among topics. Thus, different personalization methods should be used for different topics. For some, such as 'Sports', users show either high interest or no interest at all. In the latter case most articles related to the topic should be removed, with the exception of items that refer to unique events that may raise general interest according to the expressed interest. In other topics, such as 'Science&Technology', most users are interested in important articles, even if they are not interested in the general news topic. Here, the filtering technique should identify the important articles and present them to all readers. The results can be used to develop effective and simple personalization mechanisms which can be applied to the personalization of news, as well as to other domains.

Lavie, Talia and Meyer, Joachim (2010): Benefits and costs of adaptive user interfaces. In International Journal of Human-Computer Studies, 68 (8) pp. 508-524.
The paper examines the positive and the possible adverse effects of adaptive user interfaces (AUIs) in the context of an in-vehicle telematic system as a function of four factors: (1) four different levels of adaptivity (ranging from manual to fully adaptive with intermediate levels); (2) different tasks; (3) routine (familiar) and non-routine (unfamiliar) situations; and (4) different user age groups. Both experiments included three sessions during which participants drove a simple driving simulator and performed tasks with the telematic system at one of the adaptivity levels. We measured task performance times and lane position variance. Adaptivity was not always equally beneficial, and its benefits depended on a number of factors, including the frequency in which the tasks were performed, the user's age, the difficulty of the task and the user's involvement in the task. In familiar, routine situations, a fully adaptive system was beneficial for all participants, particularly older ones. In unfamiliar situations, to which the AUI was not adjusted, cognitive workload increased substantially, adversely affecting performance. Intermediate levels of adaptivity keep users involved in the task and help them become more proficient when performing both routine and non-routine tasks. However, intermediate levels of adaptivity should also be implemented with care, because they may also have adverse effects when users encounter non-routine situations.

Inbar, Ohad, Lavie, Talia and Meyer, Joachim (2009): Acceptable intrusiveness of online help in mobile devices. In: Proceedings of 11th Conference on Human-computer interaction with mobile devices and services 2009. p. 26.
The aim of this study was to examine how users perceive help on a mobile device with respect to the presentation format and the severity of the scenario the user encounters. We examined how 92 participants responded to four different formats of help offered for five different scenarios varying in their severity level using static images displayed in a web browser. The intrusiveness of the help format and the severity of the scenario affected participants' interest in receiving help. In certain conditions it may be helpful to suggest help, in particular when users do not know how to ask for it but show interest in receiving it when offered.

Technological developments and the addition of new features to existing applications or services require the inclusion of security mechanisms to protect the user. When using these mechanisms the user faces a tradeoff between more risky and more efficient or safer and less efficient use of the system. We discuss this tradeoff and present a novel complementary experimental system which provides researchers and corporations the ability to explore and model the usability and security tradeoff in the context of user interaction with security systems and psychological acceptability, even before the actual development and implementation processes have ended.

In: Proceedings of the Human Factors and Ergonomics Society 53rd Annual Meeting 2009. pp. 299-303.
The purpose of this panel was to provide a general overview and discussion of some of the most current and controversial concepts and trends in human-automation interaction. The panel was composed of eight researchers and practitioners. The panelists are well-known experts in the area and offered differing views on a variety of different human-automation topics. The range of concepts and trends discussed in this panel include: general taxonomies regarding stages and levels of automation and function allocation, individualized adaptive automation, automation-induced complacency, economic rationality and the use of automation, the potential utility of false alarms, the influence of different types of false alarms on trust and reliance, and a system-wide theory of trust in multiple automated aids.

While clinical reminders can promote adherence with evidence-based clinical guidelines, they may have unintended consequences such as alert fatigue, false alarms and increased workload, which cause clinicians to ignore them. We evaluated clinicians' response rates to suggestions to enroll patients in a nationwide clinical reminders intervention, aiming to promote prevention of clinical arthrosclerosis. Analysis of 203,164 suggestions for 108,636 patients showed that the clinicians mostly ignored suggestions from the system and followed only 21.4% of the inclusion suggestions. The data show that when physicians could choose for which patients the reminders will be generated, they mostly chose not to include patients in the clinical reminders intervention. It seems that they tried to abort the process as soon as possible, rather than complete the workflow orderly. Insights regarding the usability of clinical reminders are discussed.

Porat, Talya, Oron-Gilad, Tal and Meyer, Joachim (2009): Task-dependent processing of tables and graphs. In Behaviour and Information Technology, 28 (3) pp. 293-307.
In two experiments participants had to detect changes in periodic sinusoidal functions, displayed in either graphic or tabular displays. Graphs had a major advantage over tables when the task required considering configurations of data. Both displays led to similar results when task performance could rely on inspecting individual data points. With graphs almost all participants reported using the optimal method for detecting changes in the function, i.e., they used the method requiring the least effort to perform the task. With tables only about half used the optimal detection method, and these participants showed transfer of learning of detection methods between tasks. Experience in using a detection method led to improved performance if the new task relied on the same method of detection. These findings demonstrate the need to consider task performance methods when determining the relative value of different displays. The set of tasks for which a display is used is likely to affect performance and needs to be analysed as a whole, since methods employed for one task can affect task performance in other tasks.

The assessment of the relative value of different design features for users is of great interest for software designers. Users' evaluations are generally measured through questionnaires. We suggest that other evaluation methods, including economic measures, may provide different estimates of the relative value of features. In a laboratory experiment we created four versions of a data-entry application by independently manipulating the system's usability and aesthetics. Users' evaluations of the four experimental systems were obtained in a within-subjects design. In addition, five between-subjects experimental conditions were created, based on the evaluation method (questionnaire alone or auction and questionnaire), monetary incentives (present or absent), and experience in using the system (present or absent). In questionnaire-based responses, the systems' usability affected evaluations of usability as well as aesthetics. Similarly, the systems' aesthetics affected evaluations of both aesthetics and usability. Questionnaire-based evaluations of usability and aesthetics were not affected by experience with the system or by monetary performance incentives. Auction bids were only influenced by the system's usability: bids corresponded to the objective performance levels that could be attained with the different systems. The results suggest that by using economic methods, researchers and practitioners can obtain system evaluations that are strongly related to performance criteria and that may be more valid when the evaluation context favors task-oriented performance.

Tractinsky, Noam and Meyer, Joachim (2001): Task structure and the apparent duration of hierarchical search. In International Journal of Human-Computer Studies, 55 (5) pp. 845-860.
Research in the area of human-computer interaction (HCI) suggests that long
or variable system delays lower user satisfaction with the interaction and the
system in general. Designers cannot always control the delays in a system's
responses (e.g. when accessing remote servers), but it is possible to design
human-computer interactions so that the apparent duration of intervals will
seem minimal. One way of achieving this goal is to structure tasks so that
their apparent duration is reduced, partly by altering the number of choices
and actions required for performing the task. Two laboratory experiments
assessed the effects of the number of choices and the number of ballistic
(simple) steps in a menu search on the apparent duration of the search. Results
showed that the apparent duration increased with an increasing number of
ballistic steps, while the number of choices had no effect on estimates.
However, apparent durations were the shortest when the ratio of choices to
ballistic steps was maximized. The implications of these findings for interface
design are discussed.

Two experiments assessed the effect of displaying a boundary on duration estimates and preference ratings for dynamic displays that were shown while users waited for the system's response. Displays were either symbolic (changing numbers) or graphic (increasing rectangles) and could contain a boundary that indicated when the interval was expected to be over. Duration estimates were similar for symbolic and graphic displays and for displays with and without a boundary. However, when the displays were encountered successively, participants assessed the graphic displays as having shorter durations than the symbolic displays. Faster rates of change in both types of displays led to increased duration estimates. Although displaying a boundary did not affect duration estimates, participants preferred displays in which a boundary was shown and preferred the graphic displays over the symbolic displays. Hence, bounded graphic displays are recommended as "wait" displays for computerized applications.

Meyer, Joachim and Shinar, David (1991): Perceiving Correlations from Scatterplots. In: Proceedings of the Human Factors Society 35th Annual Meeting 1991. pp. 1537-1540.
This study investigated the effects of statistical training and various perceptual characteristics of scatterplot displays on intuitive estimates of correlations. University professors and first year undergraduate students estimated correlations from scatterplots (1) with three different levels of correlation in the data, (2) with or without a regression line, and (3) with three different types of dispersion of the data point clouds. The faculty generally used higher and a wider range of values, but both groups perceived a higher correlation when a regression line was present and both groups were equally influenced by the different types of dispersion of the point cloud. These findings indicate that the estimation of correlations from scatterplots is a perceptually based process, which is largely independent from formal statistical training.

Meyer, Joachim, Shinar, David and Leiser, David (1990): Time Estimation of Computer "Wait" Message Displays. In: D., Woods, and E., Roth, (eds.) Proceedings of the Human Factors Society 34th Annual Meeting 1990, Santa Monica, USA. pp. 360-364.
The effect of different types computer "wait" message displays on the subjective estimates of the duration of intervals in which the subject had to wait for the computer response was studied. The displays were either static (a blank screen, the phrase PLEASE WAIT, or an epigram) or dynamic (a blinking PLEASE WAIT, a round clock-like display, or an emerging string of Xs along the center of the screen). Display duration varied from 3 to 16 seconds. The dynamic displays were shown at three different rates each. Results showed differences among the displays. For dynamic displays in which a development over time can be perceived (the clock and string of Xs), there was a direct relation between the rate of change and the estimate, i.e., higher rates of change led to estimates of longer durations. The results demonstrate that some of the variables, which have been found to influence time perception in basic psychological research settings, are applicable in the user-computer setting.
