Interaction design of mobile systems is a complex activity because it requires considering new usability and user experience
aspects in order to exploit the peculiar characteristics of mobile devices, such as their pervasive and ubiquitous nature.
This paper discusses issues about designing, developing and evaluating mobile systems. Italy has a rich cultural heritage,
and the focus in this study is on the design of systems that enable interactive exploration of historical sites, not only
for enhancing the user experience but also for learning purposes. The experience of the researchers at the Interaction, Visualisation
and Usability lab, University of Bari, Italy, in designing a mobile learning system, called Explore!, which supports young
students learning ancient history during a visit to archaeological parks, is reported. The evaluation of Explore! through
systematic field studies shows that the adopted approach is able to transform the visit to archaeological parks into a more
complete and culturally rich experience. 相似文献

When there is a “bad apple” in the group, are we more likely to follow the example or compensate for their sins? Three experiments showed that whether a group member’s unethical actions lead to contagion or restitution depends on the presence of out-group observers. In Experiment 1, participants were more likely to compensate for the transgression of an in-group member than an out-group member when there were out-group observers. Experiment 2 varied the presence of out-group observers and showed that such compensatory behaviors occur only in the presence of out-group members. We suggest that the presence of out-group observers trigger a self-categorization process that induces guilt in individuals for their group members’ transgressions. Indeed, associated guilt mediated the relationship between in-group member’s unethical behavior and participants’ compensatory behavior (Experiment 3). These results suggest that norms implied by others’ behavior and group categorization are important determinants of ethical behavior. 相似文献

The present study was aimed at exploring newborns’ ability to recognize configural changes within real face images by testing newborns’ sensitivity to the Thatcher illusion. Using the habituation procedure, newborns’ ability to discriminate between an unaltered face image and the same face with the eyes and the mouth 180° rotated (i.e. thatcherized) was investigated. Newborns were able to discriminate an unaltered from the thatcherized version of the same face when stimuli were presented in the canonical upright orientation (Experiment 1), but failed to discriminate the same stimuli when they were presented upside‐down (Experiment 2). The results indicate that sensitivity to fine spatial information (defined as second‐order relational information) in processing upright faces is already present at birth. 相似文献

In previous work (Cesari & Newell, 2002), we used a graphical dimensional analysis to show that grip transitions obey the body-scaled relation K = lnL(o) + InM(o)h/(a + bM(h) + cL(h)), where L. and Mo are the object's length and mass, and Lh and Mh the length and mass of the grasper's hand. However, the generality of the equation was limited by the ad hoc graphical method that defined the lines for grip separation and by the assumption that these lines be negatively sloped and parallel to one another. This article reports an independent test of this relation by the geometrical and statistical categorization of body-scaled invariants for the transition of human grip configurations through support vector machines (SVMs). The SVM analysis confirmed the fit of linear, negatively sloped, and approximately parallel transition boundaries in the scaling of human grip configuration within a single hand. The SVM analysis has provided a theoretical refinement to the scaling model of human grip configurations. 相似文献

Although prior studies have found that people generally underweight advice from others, such discounting of advice is not universal. Two studies examined the impact of task difficulty on the use of advice. In both studies, the strategy participants used to weigh advice varied with task difficulty even when it should not have. In particular, the results show that people tend to overweight advice on difficult tasks and underweight advice on easy tasks. This pattern held regardless of whether advice was automatically provided or whether people had to seek it out. The paper discusses implications for the circumstances under which people will be open to influence by advisors. Copyright © 2006 John Wiley & Sons, Ltd. 相似文献

To provide coverging support that the proper integration of analog and propositional representational systems is associated with spatial ability, visual, auditory and bimodal brain event-related potentials were recorded from 50 right-handed Caucasian males. Sensory interaction indices were derived for these Ss who had taken the Surface Development Test of spatial ability. Product-moment correlations were computed between sensory interaction indices for eight cerebral sites and spatial ability test scores. Sensory interaction for left- and right-hemispheric regions was significantly related to spatial ability. As sensory suppression lessened, spatial ability increased. The results substantiated the theory that the visual-imaginal-analog and the auditory-verbal-propositional representational systems are implicated in spatial ability. The extent to which the cortex can inhibit or attenuate the interaction or integration between these dual-symbol systems is associated with complicated spatial task performance. 相似文献

The primary purpose of this research was to determine how imaginal and verbal encoding strategies intereact with various stimulus characteristics to either enhance or retard recognition; the secondary purpose of these studies was to test the conceptual coding hypothesis of Ellis, 1972. A between-groups multivariate factorial analysis of covariance experiment and a within-subjects multivariate factorial analysis of variance experiment were conducted. In Experiment 1 it was found that low-codability shapes were better recognized under the verbal encoding set rather than the imaginal encoding verbal encoding sets; and high-codability shapes were not better recognized than low-codability shapes. However, in Experiment 2, where instructional set was a within-subjects factor, it was found that low-codability shapes were not better recognized under the verbal encoding set than the imaginal encoding set. 相似文献
