Predicting mid-air gestural interaction with public displays based on audience behaviour
2020
Abstract Knowledge about the expected interaction duration and expected distance from which users will interact with public displays can be useful in many ways. For example, knowing upfront that a certain setup will lead to shorter interactions can nudge space owners to alter the setup. If a system can predict that incoming users will interact at a long distance for a short amount of time, it can accordingly show shorter versions of content (e.g., videos/advertisements) and employ at-a-distance interaction modalities (e.g., mid-air gestures). In this work, we propose a method to build models for predicting users’ interaction duration and distance in public display environments, focusing on …
Multidimensional prediction of work traffic crashes among Spanish professional drivers in cargo and passenger transportation
2020
The aim of this study was to examine the effect of different environmental, mechanical and individual factors associated with fatalities and serious injuries caused by work traffic accidents among cargo and passenger transport drivers (CPTD) in Spain. For this cross-sectional study, national data on work traffic accidents collected in Spain during the last 3 years were analyzed through a regression modeling approach, in order to predict the severity of traffic crashes involving CPTD. Using binary logistic regression analyses, it was found that the type of road and accident, the meteorological, light and vehicle conditions, individual characteristics and risky driving behaviors significantly…
Commuting accidents of Spanish professional drivers: when occupational risk exceeds the workplace
2019
Background. Work traffic accidents are an issue both in Spain and all over the world, and specific evidence on commuting accidents is scarce. Even though both industrial safety and welfare have been improved during the last decades, the commuting accidents rate is growing worldwide. Purpose. The aim of this study was to examine and describe the characteristics of commuting traffic crashes of Spanish professional drivers. Materials and methods. For this cross-sectional study, commuting accidents suffered by drivers during the last 12 years were analyzed. Crossed and heatmap-based analyses were performed in order to establish patterns and driver-based differences among commuting crashes. Resu…
Multitasking in Driving as Optimal Adaptation Under Uncertainty
2021
Objective The objective was to better understand how people adapt multitasking behavior when circumstances in driving change and how safe versus unsafe behaviors emerge. Background Multitasking strategies in driving adapt to changes in the task environment, but the cognitive mechanisms of this adaptation are not well known. Missing is a unifying account to explain the joint contribution of task constraints, goals, cognitive capabilities, and beliefs about the driving environment. Method We model the driver’s decision to deploy visual attention as a stochastic sequential decision-making problem and propose hierarchical reinforcement learning as a computationally tractable solution to it. The…
Worldwide research output trends on drinking and driving from 1956 to 2015.
2020
This study seeks to analyze worldwide research activity on drinking and driving of macro-actors (countries and research fields) and meso-actors (institutions, journals, articles, co-substance(s) studied) during the last 6 decades (between 1956 and 2015). Web of Science and Elsevier Scopus were searched using terms referred to drinking and driving, including terms related to vehicles and way spaces. Overlapping was excluded and absence of false positives was confirmed. Articles on alcohol with/without other psychoactive substances were assessed quantitatively (bibliometric measures). Well identified by All Science Journal Classification system (ASJC) (Elsevier Scopus), an increase in the num…
Managing Human Factors to Reduce Organisational Risk in Industry
2018
[EN] Human factors are intrinsically involved at virtually any level of most industrial/business activities, and may be responsible for several accidents and incidents, if not correctly identified and managed. Focusing on the significance of human behaviour in industry, this article proposes a multi-criteria decision-making (MCDM)-based approach to support organizational risk assessment in industrial environments. The decision-making trial and evaluation laboratory (DEMATEL) method is proposed as a mathematical framework to evaluate mutual relationships within a set of human factors involved in industrial processes, with the aim of highlighting priorities of intervention. A case study relat…
Brightness and contrast do not affect visually induced motion sickness in a passively-flown fixed-base flight simulator
2016
Abstract Background Visually Induced Motion Sickness (VIMS) or simulator sickness is often elicited by a visual stimulus that lacks the appropriate vestibular or proprioceptive feedback. In this study, we chose to investigate the effects of brightness and contrast of the visual scene on VIMS. Hypothesis We hypothesized that visual environments differing in brightness or contrast would differentially induce VIMS. The symptoms of VIMS should be most severe for the combination of high brightness and high contrast and conversely lowest for the low brightness and low contrast condition. Methods 33 healthy subjects were tested in a fixed-base flight simulator. Each subject flew in four consecutiv…
Fitbit for learning: Towards capturing the learning experience using wearable sensing
2020
The assessment of learning during class activities mostly relies on standardized questionnaires to evaluate the efficacy of the learning design elements. However, standardized questionnaires pose additional strain on students, do not provide “temporal” information during the learning experience, require considerable effort and language competence, and sometimes are not appropriate. To overcome these challenges, we propose using wearable devices, which allow for continuous and unobtrusive monitoring of physiological parameters during learning. In this paper we set out to quantify how well we can infer students’ learning experience from wrist-worn devices capturing physiological data. We coll…
The communication breakdown in the generation of the adverse event in an obstetrics and gynecology ward: a System Dynamics perspective.
2013
During the last two decades, the issue of clinical risk management became one of the key topics in the Health care sector due to the increasing attention to the patient safety and the increase in monetary and non monetary costs (insurance fees, image etc.). For this reason, in the healthcare sector have been imported risk management methods that have been successfully applied in other sector. However they are too static and linear to study such a complex and dynamic issue as the risk management. The objective of the research is to investigate, with a system dynamics perspective, the relationship between the communication and the adverse event in the Health Care, referring to the studies of …
Radical innovation by theoretical abstraction - a challenge for the user-centred designer
2016
AbstractIt is generally accepted that scientific disciplines such as psychology, sociology, and anthropology contribute beneficially to design by providing understanding of users’ needs, experiences, and desires. Arguably, however, these disciplines have more to contribute, because they include theories and models that can be applied as design frames and principles. More specifically, goal-setting, visualization, thematization, and conceptual reconfiguration are general mechanisms through which theories translate into design contributions. Actualizing radical design solutions via these mechanisms is discussed: theories provide appropriate means of abstraction, which allows ‘distance’ from u…
