Veiligheid op de werkvloer

Arbeidsongevallen zijn vaak te wijten aan menselijk gedrag, hoe mensen met elkaar omgaan en hoe ze met risico’s en richtlijnen omgaan. Bewust bezig zijn met veiligheid is een noodzakelijke voorwaarde voor veiligheid op de werkvloer. Door middel van cursussen, trainingen en ‘risk assessment’ kan een beter begrip en draagvlak gecreëerd worden voor veiligheid op de werkvloer. Dit is vooral het terrein van de Arbowetgeving. Omgevingsbewustzijn is echter ook belangrijk voor veiligheid op de werkvloer. Een adequaat inzicht in de huidige situatie is belangrijk om de gevolgen van bepaalde handelingen te kunnen beoordelen en om nadelige en schadelijke gevolgen en daarmee ongelukken te voorkomen. De menselijke vaardigheden schieten echter vaak te kort in complexe situaties en onder tijdsdruk en werkdruk. Doel van dit onderzoek is om na te gaan hoe technologie – en vooral Ambient Intelligence – kan bijdragen aan het verbeteren van de menselijke vaardigheden als het gaat om het beoordelen van een situatie en de gevolgen van handelingen. In dit onderzoek is gekeken hoe omgevingsbewustzijn tot stand komt, welke factoren daarbij een rol spelen en hoe dit proces in positieve en negatieve zin kan worden beïnvloed. Verder is gekeken naar de stand van zaken en de (technologische) ontwikkelingen op andere terreinen waar omgevingsbewustzijn een belangrijke rol speelt, zoals hulpverlening, defensie en luchtverkeersleiding. Die bevindingen zijn vervolgens geprojecteerd in de context van veiligheid op de werkvloer. De conclusie is dat Ambient Intelligence omgevingsbewustzijn kan verbeteren op alle niveaus. Ambient Intelligence verhoogt de perceptie, verbetert het inzicht en stelt in staat om de gevolgen van handelingen beter te kunnen inschatten. Omdat veiligheid op de werkvloer een uitgebreid gebied is en omdat ongelukken zeer divers van aard zijn, van incidenteel tot structureel, is de aanbeveling om aan de hand van een aantal geselecteerde ‘use-cases’ in de volgende fase meer focus en verdieping aan te brengen.

Deconstructing immersion in the experience economy framework for immersive dining experiences through mixed reality.

In this study, we test the immersive character in an interactive content narrative developed for Microsoft HoloLens 2 mixed reality glasses in the dining context. We use retrospective think aloud protocol (RTAP) and galvanic skin response (GSR) to explore different types of immersion that can be created through interactive content narratives. Leaning on the core dimensions of the experience economy, we expand the current understanding on the role of immersion through integration of four immersive experience facilitators. The study revealed that these immersive experience facilitators occur simultaneously and can be enhanced through interactive content narrative design. Perceived novelty and curiosity were identified as key determinants to keep consumers engaged in the immersive experience and engage with the content. The study verifies the use of galvanic skin response in combination with retrospective think aloud protocol as a suitable approach to measure emotional engagement potential in interpreting consumers’ recollection of immersive experiences.

Creating the Difference

‘Creating the Difference’ is the theme of the 2014 edition of the Chi Sparks conference. It is also the challenge that the Human-Computer Interaction (HCI) community is facing today. HCI is a creative field where practitioners engage in design, production, and evaluation of interactions between people and digital technology. Creating excellent interfaces for people, they make a difference in media and systems that people are eager to use. Usability and user experience are fundamental for achieving this, as are abilities at the forefront of technology, but key to a successful difference is getting the right concepts, addressing genuine, intrinsic, human needs. Researchers and practitioners contribute to this area from theory as well as practice by sharing, discussing, and demonstrating new ideas and developments. This is how HCI creates a difference for society, for individuals, businesses, education, and organizations. The difference that an interactive product or service makes might lie in the concept of it but also in the making, the creation of details and the realisation. It is through powerful concepts and exceptional quality of realisation that innovation is truly achieved. At the Chi Sparks 2014 conference, researchers and practitioners in the HCI community convene to share and discuss their efforts on researching and developing methods, techniques, products, and services that enable people to have better interactions with systems and other people. The conference is hosted at The Hague University of Applied Sciences, and proudly built upon the previous conferences in Arnhem (2011) and Leiden (2009).

Protein intake, nutritional status and outcomes in ICU survivors

The Living Environment and Thermal Behaviours of Older South Australians

Ageing brings about physiological changes that affect people’s thermal sensitivity and thermoregulation. The majority of older Australians prefer to age in place and modifications to the home environment are often required to accommodate the occupants as they age and possibly become frail. However, modifications to aid thermal comfort are not always considered. Using a qualitative approach this study aims to understand the thermal qualities of the existing living environment of older South Australians, their strategies for keeping cool in hot weather and warm in cold weather and to identify existing problems related to planning and house design, and the use of heating and cooling. Data were gathered via seven focus group sessions with 49 older people living in three climate zones in South Australia. The sessions yielded four main themes, namely ‘personal factors’, ‘feeling’, ‘knowing’ and ‘doing’. These themes can be used as a basis to develop information and guidelines for older people in dealing with hot and cold weather.

Prenatal anxiety recognition model integrating multimodal physiological signal

Anxiety among pregnant women can significantly impact their overall well-being. However, the development of data-driven HCI interventions for this demographic is often hindered by data scarcity and collection challenges. In this study, we leverage the Empatica E4 wristband to gather physiological data from pregnant women in both resting and relaxed states. Additionally, we collect subjective reports on their anxiety levels. We integrate features from signals including Blood Volume Pulse (BVP), Skin Temperature (SKT), and Inter-Beat Interval (IBI). Employing a Support Vector Machine (SVM) algorithm, we construct a model capable of evaluating anxiety levels in pregnant women. Our model attains an emotion recognition accuracy of 69.3%, marking achievements in HCI technology tailored for this specific user group. Furthermore, we introduce conceptual ideas for biofeedback on maternal emotions and its interactive mechanism, shedding light on improved monitoring and timely intervention strategies to enhance the emotional health of pregnant women.
