The development of new visual displays and speach synthesizers leads to the on board presentation of additional information to the car driver. A series of laboratory and field experiments was carried out to compare visual, auditory, and partly combined presentation of binary and textual information. From the results recommendations for practical design can be given. Binary alarms which occur seldomly and with high priority have to be a dynamic signal, e. g. a blinking lamp optionally supported by an intermittent auditory signal. For textual information a voice warning system is recommended.

We investigated whether adding product information in mobile commerce improved consumers’ attitudes toward a product and whether this relationship was moderated by consumption goals. We conducted two field experiments in which we recruited parents in Korea and the USA and asked them how they evaluated two childcare hybrid products (HPs) newly developed by Samsung Electronics designers. The results revealed that participants exposed to additional information about the HPs evaluated them more favorably than those who were not exposed. However, this relationship disappeared when a consumption goal was activated. Our findings establish a dynamic relationship between information seeking and consumption goals, asking designers to rethink their rule of thumb in the mobile commerce context.

Multimodal Signalling

Courting males often perform different behavioural displays that demonstrate aspects of their quality. Male fiddler crabs, Uca sp., are well known for their repetitive claw-waving display during courtship. However, in some species, males produce an additional signal by rapidly stridulating their claw, creating a ‘drumming’ vibrational signal through the substrate as a female approaches, and even continue to drum once inside their burrow. Here, we show that the switch from waving to drumming might provide additional information to the female about the quality of a male, and the properties of his burrow (multiple message hypothesis). Across males there was, however, a strong positive relationship between aspects of their waving and drumming displays, suggesting that drumming adheres to some predictions of the redundant signal hypothesis for multimodal signalling. In field experiments, we show that recent courtship is associated with a significant reduction in male sprint speed, which is commensurate with an oxygen debt. Even so, males that wave and drum more vigorously than their counterparts have a higher sprint speed. Drumming appears to be an energetically costly multimodal display of quality that females should attend to when making their mate choice decisions.

Signal Detectability

Using a task which closely simulated the actual output from a sonar device, the performance of 12 subjects was observed for a total of 115 hr in repeated prolonged monitoring sessions under auditory, visual, and dual-mode display conditions. Despite an underlying basic superiority of signal discriminability on the visual display, and the occurrence of long-term practice effects, detection rate was consistently and substantially higher under the auditory condition, and higher again with the dual-mode display. These results are similar to those obtained by earlier workers using artificial laboratory tasks for shorter periods, and are consistent with the notion that auditory displays have greater attention-gaining capacity in a “vigilance” situation. A further comparison of the auditory and visual displays was then made in an “alerted” situation, where the possible occurrence of a signal was indicated by a warning stimulus in the alternative sensory mode. Ten subjects were observed for a total of 57 hr in these conditions, under which performance was found to be clearly superior with the visual display. Cross-modal correlations of performance indicated the presence of a common factor of signal detectability within subjects. It was concluded that where efficiency both in the initial detection of targets and their subsequent identification and tracking are equally important, the best solution would seem to be to retain both auditory and visual displays and to ensure that these are monitored concurrently.

While design theories in visual displays have been well developed and further refined, relatively little research has been conducted on design theories and models in auditory displays. The existing discussions mainly account for functional mappings between sounds and referents, but these do not fully address design aspects of auditory displays. To bridge the gap, the present proposal focuses on design affordances in sound design among many design constructs. To this end, the definition and components of design affordances are briefly explored, followed by the auditory display examples of those components to gauge whether sound can deliver perceived affordances in interactive products. Finally, other design constructs, such as feedback and signifier, are discussed together with future work. This exploratory proposal is expected to contribute to elaborating sound design theory and practice.

Duplicate Bug Reports

During software maintenance, bug reports are widely employed to improve the software project’s quality. A developer often refers to stowed bug reports in a repository for bug resolution. However, this reference process often requires a developer to pursue a substantial amount of textual information in bug reports which is lengthy and tedious. Automatic summarization of bug reports is one way to overcome this problem. Both supervised and unsupervised methods are effectively proposed for the automatic summary generation of bug reports. However, existing methods disregard the significance of duplicate bug reports in summarizing bug reports. In this study, we propose a PageRank-based Summarization Technique (PRST), which utilizes the textual information contained in bug reports and additional information in associated duplicate bug reports. PRST uses three variants of PageRank-based on Vector Space Model (VSM), Jaccard, and WordNet similarity metrics. These variants are utilized to calculate the textual similarity of the sentences between the master bug reports and their duplicates. PRST further trains a regression model and predicts the probability of sentences belonging to the summary. Finally, we combine the values of PageRank and regression model scores to rank the sentences and produce the summary for the master bug reports. In addition, we construct two corpora of bug reports and duplicates, i.e. MBRC and OSCAR. Empirical results suggest that PRST outperforms the state-of-the-art method BRC in terms of Precision, Recall, F-score, and Pyramid Precision. Meanwhile, PRST with WordNet achieves the best results against PRST with VSM and Jaccard.

Using Data

Today, crowd computing is successfully applied for many information processing problems in a variety of domains. One of the most acute issues with crowd-powered systems is the quality of results (as humans can make errors). Therefore, a number of methods have been proposed to process the results obtained from the crowd in order to compensate human errors. Most of the existing methods of processing contributions are constructed based on a (natural) assumption that the only information available is unreliable data obtained from the crowd. However, in some cases, additional information is available, and it can be utilized in order to improve the overall quality of the result. The paper describes a crowd computing application for community tagging of running race photos. It presents a utility analysis to identify situations in which community photo tagging is a reasonable choice. It also proposes a data fusion model making use of runners’ location information recorded in their Global Positioning System (GPS) tracks. Field experiments with the applications show that community-based tagging can collect enough contributors to process photosets from medium-sized running events. Simulation results confirm, that the use of data fusion in processing the results of crowd computing is a promising technique, and the use of probabilistic graphical models (e.g., Bayesian networks) for data fusion allows one to smoothly increase the quality of the results with an increase of the available information.

Functional Modulation

A biologically relevant event is normally the source of multiple, typically correlated, sensory inputs. To optimize perception of the outer world, our brain combines the independent sensory measurements into a coherent estimate. However, if sensory information is not readily available for every pertinent sense, the brain tries to acquire additional information via covert/overt orienting behaviors or uses internal knowledge to modulate sensory sensitivity based on prior expectations. Cross-modal functional modulation of low-level auditory areas due to visual input has been often described; however, less is known about auditory modulations of primary visual cortex. Here, based on some recent evidence, we propose that an unexpected auditory signal could trigger a reflexive overt orienting response towards its source and concomitantly increase the primary visual cortex sensitivity at the locations where the object is expected to enter the visual field. To this end, we propose that three major functionally specific pathways are employed in parallel. A stream orchestrated by the superior colliculus is responsible for the overt orienting behavior, while direct and indirect (via higher-level areas) projections from A1 to V1 respectively enhance spatiotemporal sensitivity and facilitate object detectability.

After some introductory general remarks on recent investigations involving population models, two broad classes of stochastic model are discussed further, viz. spatial nearest-neighbour lattice models and doubly stochastic models.In Section 1 of the paper, the first type of model is considered primarily for its relevance to recent work by the author and others affecting the practical design and analysis of replicated field experiments.In Section 2, doubly stochastic processes are discussed more theoretically, particularly models investigated recently by the author involving infinitesimal transition operators in continuous time linear in the (variable) parameters.Some new numerical results on extinction and other ‘absorption' probabilities are presented; these are intended to throw further light on the extent to which the assumption of ‘white-noise' variability of the parameters can be a useful approximation to more realistic models.

The main objective of the TechTIDE project (warning and mitigation technologies for travelling ionospheric disturbances effects) is the development of an identification and tracking system for travelling ionospheric disturbances (TIDs) which will issue warnings of electron density perturbations over large world regions. The TechTIDE project has put in operation a real-time warning system that provides the results of complementary TID detection methodologies and many potential drivers to help users assess the risks and develop mitigation techniques tailored to their applications. The TechTIDE methodologies are able to detect in real time activity caused by both large-scale and medium-scale TIDs and characterize background conditions and external drivers, as an additional information required by the users to assess the criticality of the ongoing disturbances in real time. TechTIDE methodologies are based on the exploitation of data collected in real time from Digisondes, Global Navigation Satellite System (GNSS) receivers and Continuous Doppler Sounding System (CDSS) networks. The results are obtained and provided to users in real time. The paper presents the achievements of the project and discusses the challenges faced in the development of the final TechTIDE warning system.

Possible Cause

Pilots often turn off the auditory displays which are provided to improve their performance (Weiner, 1977; Veitengruber, Boucek, & Smith, 1977). The intensity of the auditory display is often cited as a possible cause of this behavior (Cooper, 1977). However, the processing of the additional information is a concurrent task demand which may increase subjective workload (Wickens & Yeh, 1983; McCloy, Derrick, & Wickens, 1983). Pilots may attempt to reduce subjective workload at the expense of performance by turning off the auditory display. Forty undergraduate males performed a visual search task. Three conditions: auditory display on, auditory display off, and subject's choice were run in combination with nine levels of visual display load. The auditory display, a 4000 Hz tone with a between-subject intensity of 60 dB(A), 70 dB(A), 80 dB(A), and 90 dB(A), indicated that the target letter was in the lower half of the search area. NASA-TLX (Task Load Index) was used to measure the subjective workload of the subjects after each block of trials (Hart & Staveland, 1988). A non-monotonic relationship was found between auditory display intensity and auditory display usage. Evidence was found that the auditory display increased some aspects of subjective workload– physical demands and frustration. Furthermore, there was a dissociation of performance and subjective workload in the manner predicted by Wickens – Yeh (1983). The implications of these results for display design are discussed.
