Augmented Reality Applications: The Impact of Usability and Emotional Perceptions on Tourists’ App Experiences

2019

There is a rising amount of research contributing to the knowledgebase of Augmented Reality (AR) application usage. However, up until now there is no sound understanding about how the emotional perception of AR application users impact on different types of experience. This paper aspires to contribute to this gap by analysing the link between usability, emotional perception (i.e. entertainment, playfulness and enjoyment), two types of experience viz. action- and emotional experience and users’ intention to use the app in a travel context. 796 questionnaires show that emotional experience is driven by entertainment while action experience is mainly triggered by playfulness. However, only emo…

Online prevention programmes for university students: stakeholder perspectives from six European countries

2021

Abstract Background Students beginning university are at a heightened risk for developing mental health disorders. Online prevention and early intervention programmes targeting mental health have the potential to reduce this risk, however, previous research has shown uptake to be rather poor. Understanding university stakeholders’ (e.g. governing level and delivery staff [DS] and students) views and attitudes towards such online prevention programmes could help with their development, implementation and dissemination within university settings. Methods Semi-structured interviews, focus groups and online surveys were completed with staff at a governing level, university students and DS (i.e.…

Die CO 2 -Messung im Atemgas

1997

UNLABELLED Currently, even in prehospital emergency medicine (PEM), continuous end-tidal CO2 monitoring is frequently used as a sensitive and non-invasive technique in ventilated patients. Due to its central role, the continuous measurement of exhaled CO2 provides immediate information about the status of three essential functions of the organism: ventilation, circulation, and metabolism. METHODS Recent literature, obtained by a computer-guided search (Winspirs), and product information of all currently available capnometry devices were reviewed in detail. Firstly, the theoretical background of different CO2-measurement methods and techniques is described. Secondly, indications and specific…

Process Evaluation of an eHealth Intervention (Food4toddlers) to Improve Toddlers' Diet : Randomized Controlled Trial

2020

Background Parents seek trustworthy information online to promote healthy eating for their toddlers. Such information must be perceived as relevant and easy to implement and use. Objective The objectives of this study were to conduct a process evaluation of the electronic health (eHealth) intervention (Food4toddlers) targeting food environment, parental feeding practices, and toddlers’ diet and to examine possible differences in these areas according to education and family composition. Methods A 2-armed randomized controlled trial, including 298 parent–toddler dyads from Norway, was conducted in 2017. In total, 148 parents in the intervention group received access to an intervention websi…

Virtual reality and 3D printing improve preoperative visualization of 3D liver reconstructions-results from a preclinical comparison of presentation …

2021

BACKGROUND: Preoperative three-dimensional (3D) reconstructions for liver surgery planning have been shown to be effective in reduction of blood loss and operation time. However, the role of the ‘presentation modality’ is not well investigated. We present the first study to compare 3D PDFs, 3D printed models (PR) and virtual reality (VR) 3D models with regard to anatomical orientation and personal preferences in a high volume liver surgery center. METHODS: Thirty participants, 10 medical students, 10 residents, 5 fellows and 5 hepatopancreatobiliary (HPB) experts, assigned the tumor-bearing segments of 20 different patient’s individual liver reconstructions. Liver models were presented in a…

An mHealth App for Supporting Quitters to Manage Cigarette Cravings With Short Bouts of Physical Activity: A Randomized Pilot Feasibility and Accepta…

2016

BackgroundWhile gains in reducing smoking rates in Finland have been made, prevalence rates are still substantial. Relapse rates among smokers engaged in quit-smoking programs are high. Physical activity has been proposed as one means to help smokers manage cravings. Software and apps on mobile phone and handheld devices offer an opportunity to communicate messages on how to use physical activity to manage cravings as part of quit-smoking programs. ObjectiveWe aimed to test the feasibility, acceptability, usability, and preliminary efficacy of an mHealth mobile phone app, Physical activity over Smoking (PhoS), to assist smokers in quitting smoking in a randomized controlled trial. The app w…

Personal health promotion through personalized health technologies — Nuadu experience

2009

Poor lifestyles — overweight, unhealthy diet, physical inactivity, sleep deprivation, and stress — are significant risk factors to chronic illnesses, which cause majority of the health care costs. Hence, behavioral change towards healthy lifestyles is one of the keys to health care cost containment. Personal health systems (PHS) offer tools to support behavioral change. As health risks, personal needs and preferences vary from an individual to another, personalization of the PHS is needed. In Nuadu project we have developed a PHS integrating several different personal health technologies. This system was studied in a large (N=354) randomized controlled trial where employees with several hea…

Introduction Monitoring and reduction of aversive tension is a core issue in dialectical behaviour therapy of patients. It has been shown that aversive tension is increased in adult borderline personality disorder and is linked to low emotion labelling ability. However, until now there is no documented evidence that patients with anorexia nervosa suffer from aversive tension as well. Furthermore the usability of a smartphone application for ambulatory monitoring purposes has not been sufficiently explored. Methods and analysis We compare the mean and maximum self-reported aversive tension in 20 female adolescents (12–19 years) with anorexia nervosa in outpatient treatment with 20 healthy co…

Exergames on Line for Childhood Obesity: Using a Web Platform as an Ambulatory Program to Increase the Acceptance and Adherence to Physical Activity …

2016

Many initiatives exist to promote physical activity (PA) in children but dropouts are a very common outcome. Information and Communication Technologies (ICTs) are considered as useful tools to promote adherence in PA. This study analyzes the acceptance and adherence of an Internet-based exergame (MOVE-IT) to promote PA compared to a non-technological ambulatory intervention (NTI). The role of clinicians support is also analyzed. Thirty one obese children (9–15 aged) were asked to do an exercise routine (3 times/week along 3 months), using a pamphlet (NTI) or MOVE-IT web. In addition, MOVE-IT participants were divided into two groups, with and without (S-EBW/NS-EBW) weekly support. Results s…

Measuring the Effects of Sharing Mobile Health Data During Diabetes Consultations: Protocol for a Mixed Method Study

2020

Background There is rising demand for health care’s limited resources. Mobile health (mHealth) could be a solution, especially for those with chronic illnesses such as diabetes. mHealth can increases patients’ options to self-manage their health, improving their health knowledge, engagement, and capacity to contribute to their own care decisions. However, there are few solutions for sharing and presenting patients’ mHealth data with health care providers (HCPs) in a mutually understandable way, which limits the potential of shared decision making. Objective Through a six-month mixed method feasibility study in Norway, we aim to explore the impacts that a system for sharing patient-gathered…
