Interweaving visual and audio-haptic augmented reality for urban exploration

2018

While ordinary touchscreen-based interfaces on urban explorer applications draw much of a user's attention onto the screen, visual and audio-haptic augmented reality interfaces have emerged as the two main streams for enabling direct focus on the surroundings. However, neither interface alone satisfies users in the highly dynamic urban environment. This research investigates how the two complementary augmentation can coexist on one system and how people adapt to the situation by selecting the more suitable interface. A prototype was deployed in a field experiment in which participants explored points of interest in an urban environment with both interfaces. The engagement with the surroundi…

A wearable multimodal interface for exploring urban points of interest

2015

Locating points of interest (POIs) in cities is typically facilitated by visual aids such as paper maps, brochures, and mobile applications. However, these techniques require visual attention, which ideally should be on the surroundings. Non-visual techniques for navigating towards specific POIs typically lack support for free exploration of the city or more detailed guidance. To overcome these issues, we propose a multimodal, wearable system for alerting the user of nearby recommended POIs. The system, built around a tactile glove, provides audio-tactile cues when a new POI is in the vicinity, and more detailed information and guidance if the user expresses interest in this POI. We evaluat…

‘I think I will need help’: A systematic review of who facilitates the recovery from gender‐based violence and how they do so

2020

Context A key to advancing the eradication of gender-based violence (GBV) is knowing how to recover from it. Objective To identify the changes that are indicators of having overcome GBV and determine the role of various support networks. Search strategy We systematically searched Web of Science. Inclusion criteria Publications whose abstracts contained a minimum of two of the following words: (a) support or network or solidarity, (b) violence and (c) recovery or healing. Data extraction and synthesis Of the 273 documents retrieved, 52 were used using a narrative synthesis approach. Main results For recovery, women must reconnect with themselves, with their environment and with the world in …

Simple and Flexible Power Loss Minimizer With Low-Cost MCU Implementation for High-Efficiency Three-Phase Induction Motor Drives

2021

This paper presents a simple, practical and low-cost implementation of a power losses minimization algorithm for three-phase induction motors taking also into account both iron core losses and magnetic saturation. The algorithm evaluates, in real-time, the optimal direct axis magnetizing flux component for efficiency enhancement of the drive. A further advantage of the proposed technique is represented by a flexible and low-cost implementation by means of an ATMEL ATSAM3X8E microcontroller. The power loss minimization algorithm is tested preliminarily by means of several simulations, then, experimentally validated by applying the proposed control strategy on a 5.5 kW Field Oriented Control …

Technology management, networking positions and work/life boundaries among working adult students

2021

In this digitalised world, crossing boundaries between life domains is becoming increasingly easy. We are constantly faced with the need to define whether we are online or offline, and technology management is now an integral part of daily life. Technology management, which is affected by the individual's networking position, has different components: connectivity management, online self-presentation and privacy management. The objective of this study is to explore technology management strategies among working adult students. The study identifies three networking positions: socio-affective enthusiasts, context-contingent pragmatists and pragmatic avoiders. These three groups have specific …

A questionnaire to assess parental perception of barriers towards active commuting to school (PABACS): Reliability and validity

2019

Abstract Introduction Parental barriers are a key factor to determine physical activity behaviors, such as active commuting to school in young people. The purpose of this study was to test the reliability and validity of a questionnaire which addresses parental barriers towards active commuting to school. Methods This paper describes the development, following the Delphi method, and the validation of a Likert-scale questionnaire of 23 items (Parental Perception of Barriers towards Active Commuting to School (PABACS)) designed to determine the main parental barriers. These barriers are categorized into 3 scales (general, walking, and cycling barriers) and the overall questionnaire. A total o…

MAVIE-Lab Sports: a mHealth for Injury Prevention and Risk Management in Sport

2018

International audience; Smart-phones technology and the development of mHealth (Mobile Health) applications offer an opportunity to design intervention tools to influence health behavior changes. The MAVIE-Lab is a mHealth application including a DSS (Desicion Support System) to assist in the personalized evaluation of HLIs (Home, Leisure and Sport Injuries) risk and to promote the adoption of prevention measures. MAVIE-Lab Sports will be the first module of the mobile application. The purpose of this PhD project is to improve a particular module of MAVIE-Lab, devoted to sports (MAVIE-Lab Sports), in different aspects: statistical modeling, design and ergonomics. It also aims to evaluate sy…

Co-design of a Virtual Training Tool with Emergency Management Stakeholders for Extreme Weather Response

2018

Emergency services usually prepare for the most frequent or predictable types of disasters, such as fires. However, preparation for complex, unpredictable disaster scenarios is infrequent, probably because of high resource demand and difficulty of covering dynamic training needs of multiple stakeholders. The use of serious game techniques as the core of simulated or virtual training tools opens for new ways of training and learning in emergency and crisis scenarios. However, the number of virtual training tools customized to specific disaster or crisis scenario that address needs of diverse user groups is limited. Existing tools are often tailored with a particular geographical setting and …

The Integrated Migrant worker Safety Training Evaluation Model: IMSTEM

2021

Abstract This paper presents the development of the IMSTEM (Integrated Migrant worker Safety Training Evaluation Model), which aims to provide guidance on how to evaluate the transfer of safety training of migrant workers. Addressing the lack of rigorous safety training evaluation frameworks, the IMSTEM, using a mixed methods, multi-source approach, covers the deficiencies of previous models. The IMSTEM has its foundations in three main sources: a) the integration of safety training literature in relation to migrant workers; b) the theoretical framework of realist evaluation, which enables evaluators to understand what works for whom in which circumstances; and c) the integration of the tra…
