Key factors in the public acceptance of biometric systems are non-intrusiveness, ease of use, and trust. In this paper we propose a biometric identity verification system consisting of a non-intrusive virtual mirror interface, and a face verifier using fractal coding to store the biometric template on a smart-card. The virtual mirror interface assists the user to obtain a frontal face image. The limited memory requirements of the fractal template and processing requirements of fractal decoding enable the implementation of the verification procedure on a smart-card. This set-up facilitates non-intrusive and easy to use biometric verification, and provides trust by adding a visualization to the biometric yes/no decision. Since the system does not require user assistance, it enables secure access over the Internet.

Particle image velocimetry has been widely used in various sectors from the automotive to aviation, research, and development, energy, medical, turbines, reactors, electronics, education, refrigeration for flow characterization and investigation. In this study, articles examined in open literature containing the particle image velocimetry techniques are reviewed in terms of components, lasers, cameras, lenses, tracers, computers, synchronizers, and seeders. The results of the evaluation are categorized and explained within the tables and figures. It is anticipated that this paper will be a starting point for researchers willing to study in this area and industrial companies willing to include PIV experimenting in their portfolios. In addition, the study shows in detail the advantages and disadvantages of past and current technologies, which technologies in existing PIV laboratories can be renewed, and which components are used in the PIV laboratories to be installed.

Research showed that more than 30% of patients with Posttraumatic Stress Disorder (PTSD) do not benefit from evidence- based treatments: Trauma-Focused Cognitive Behavioral Therapy (TF-CBT) or Eye Movement Desensitization and Reprocessing (EMDR). These are patients with prolonged and multiple traumatization, with poor verbal memory, and patients with emotional over-modulation. Retelling traumatic experiences in detail is poorly tolerated by these patients and might be a reason for not starting or not completing the recommended treatments. Due to lack of evidence, no alternative treatments are recommended yet. Art therapy may offer an alternative and suitable treatment, because the nonverbal and experiential character of art therapy appears to be an appropriate approach to the often wordless and visual nature of traumatic memories. The objective of this pilot study was to test the acceptability, feasibility, and applicability of trauma-focused art therapy for adults with PTSD due to multiple and prolonged traumatization (patients with early childhood traumatization and refugees from different cultures). Another objective was to identify the preliminary effectiveness of art therapy. Results showed willingness to participate and adherence to treatment of patients. Therapists considered trauma-focused art therapy feasible and applicable and patients reported beneficial effects, such as more relaxation, externalization of memories and emotions into artwork, less intrusive thoughts of traumatic experiences and more confidence in the future. The preliminary findings on PTSD symptom severity showed a decrease of symptoms in some participants, and an increase of symptoms in other participants. Further research into the effectiveness of art therapy and PTSD is needed.

Werkgevers in de Europese Unie gebruiken draagbare technologie, zoals smartphones, om er preventief voor te zorgen dat hun bedrijf geen besmettingshaard wordt. Door bron- en contactonderzoek en tracking van werknemers proberen zij dat te bereiken. Maar hoe zit dit in relatie tot de Europese AVG-regels? Stefania Marassi van de Haagse Hogeschool stelt dat er strikte voorwaarden moeten zijn om deze technologie te mogen gebruiken.

Dit boekje is uitgegeven in het kader van de inaugurele rede van Richard Griffioen, lector Animal Assisted Interventions (AAI). De inhoud van het lectoraat is zeer divers en richt zich op de impact van AAI (in de zorg) op het welzijn van mens en dier en het beïnvloeden van de mindset in de maatschappij. Het One Health concept, waarin het welzijn van de mens én het dier hand in hand gaan, speelt hierbij een belangrijke rol. Het lectoraat richt zich ook op nieuwe technologieën zoals virtual reality en robotica toepassingen. Het doel is om programma’s te ontwikkelen die zich richten op de hond, boerderijdieren en paarden.

New online stores and digital distribution methods have led to the development of alternative monetization models for video-games, such as free-to-play games with advertisements. Although there are many games using such models, until now the effect on the player experience from such interruptions has not been studied. In this controlled experiment, we requested that participants (N=236) play one of three different versions of a platformer game with: 1) no interruptions, 2) 30-second video advertisements, and 3) a multiple-choice questionnaire. We then evaluated the effects on the player experience. The study shows differences in their experiences, namely in: competence, immersion, annoyance, affects, and the reliability of the questionnaire answers. The contribution of this work is to identify which player experience variables are affected by interruptions, which can be valuable for selecting the business model and guiding the game design process.

Office well-being aims to explore and support a healthy, balanced and active work style in office environments. Recent work on tangible user interfaces has started to explore the role of physical, tangible interfaces as active interventions to explore how to tackle problems such as inactive work and lifestyles, and increasingly sedentary behaviours. We identify a fragmented research landscape on tangible Office well-being interventions, missing the relationship between interventions, data, design strategies, and outcomes, and behaviour change techniques. Based on the analysis of 40 papers, we identify 7 classifications in tangible Office well-being interventions and analyse the intervention based on their role and foundation in behaviour change. Based on the analysis, we present design considerations for the development of future tangible Office well-being design interventions and present an overview of the current field and future research into tangible Office well-being interventions to design for a healthier and active office environment.

Zorgcapaciteit kan een belangrijke schakel zijn tussen multi-probleem omstandigheden en ongunstige ontwikkeling van kinderen. Deze studie heeft als doel om de zorgcapaciteit en de correlaties daartussen te onderzoeken in zeer kwetsbare multiprobleemgezinnen in Rotterdam, Nederland. Zorgcapaciteit (algemeen, emotioneel en instrumenteel) werd prospectief beoordeeld bij 83 zeer kwetsbare vrouwen met behulp van video-observaties van dagelijkse zorgtaken, zes weken postpartum. Ondersteunende gegevens werden verzameld op drie tijdstippen: bij inclusie, zes weken na inclusie en zes weken postpartum, en deze omvatten psychologische symptomen, zelfredzaamheid, problematische levensdomeinen, thuisomgeving, inkomen, depressie, angst en stress. Zwangerschaps- en bevallingsgerelateerde informatie werd verzameld bij verloskundigen. De scores voor zorgverlening door de moeder waren gemiddeld van onvoldoende kwaliteit. Moeders die in een onveilige thuisomgeving leefden (B = 0,62) en moeders met meer problematische levensdomeinen (≤3 domeinen, B = 0,32) vertoonden significant hogere instrumentele zorgcapaciteiten. Andere variabelen waren niet gerelateerd aan zorgcapaciteit. De zorgcapaciteit in deze zeer kwetsbare populatie was van onvoldoende kwaliteit. In de meeste gevallen was er echter geen significant verband tussen zorgzaamheid en de variabelen die gerelateerd zijn aan kwetsbaarheid. Dit betekent dat een mogelijk verband tussen kwetsbaarheid en zorgcapaciteit kan worden veroorzaakt door de interactie tussen verschillende problemen, in plaats van door het type of de omvang van de zorg.
