This papers presents some ideas to use so-called software agents as a software representation of a product not only during manufacturing but also during the whole life cycle of the product. Software agents are autonomous entities capable of collecting useful information about products. By their design and capabilities software agents fit well in the concept of ubiquitous computing. We use these agents in our newly developed manufacturing process. This paper discusses further use of agent technology.

Programmed control systems are ubiquitous in the present-day world. In current educational practice, however, these systems are hardly being addressed, and little is known about children’s spontaneous understandings about such systems. Therefore, we explored pupils’ understandings prior to instruction in three concrete settings: a car park, an elevator, and an autonomous robot. We analysed written responses from 49 Grade 3 (aged 7 to 10) and Grade 6 pupils (aged 10 to 13) to assess their understandings from two perspectives: the user and the system programmer perspective. Results indicate that most pupils were capable describing programmed systems from a user perspective point of view but found it hard to describe the system programmer perspective. Substantial differences were found between the contexts. The car park context evoked richer descriptions for the user perspective and the system programmer perspective in comparison to the elevator and autonomous robot contexts.

Within Human Activity Recognition (HAR), there is an insurmountable gap between the range of activities performed in life and those that can be captured in an annotated sensor dataset used in training. Failure to properly handle unseen activities seriously undermines any HAR classifier's reliability. Additionally within HAR, not all classes are equally dissimilar, some significantly overlap or encompass other sub-activities. Based on these observations, we arrange activity classes into a structured hierarchy. From there, we propose Hi-OSCAR: a Hierarchical Open-set Classifier for Activity Recognition, that can identify known activities at state-of-the-art accuracy while simultaneously rejecting unknown activities. This not only enables open-set classification, but also allows for unknown classes to be localized to the nearest internal node, providing insight beyond a binary “known/unknown” classification. To facilitate this and future open-set HAR research, we collected a new dataset: NFI_FARED. NFI_FARED contains data from multiple subjects performing nineteen activities from a range of contexts, including daily living, commuting, and rapid movements, which is fully public and available for download.

Conference poster Digitally controlled systems, such as elevators, washing machines, and traffic lights, are ubiquitous in children's present-day world. However, in current educational practice, such systems are hardly being addressed, and little is known about children's initial understandings about such systems in concrete situations. Therefore, we explored grade 3 and grade 6 pupils' understandings of digital control systems in the contexts of a car park, an elevator, and an autonomous robot. We interviewed 48 pupils to explore their initial understanding of the system at hand from the perspectives of the user, the computer, and the programmer perspective. The interviews were analyzed through a directed content analysis. Results from three perspectives and three contexts are described.

ICT is veel meer dan een hulpmiddel bij onderwijs en opleiding: zij provoceert een voortdurend nieuwe kijk op de essentie van leren en daarmee ook op het leraarschap. Opvallend is dat ICT in onderwijs penetreert nog voordat er enig model of theorievorming over haar bijdrage gevormd is; dat is pragmatisch en opportunistisch. Sterker nog: als we achteraf kijken naar hervormingen van onderwijsopvattingen, dan worden ze vaak aangedreven door technologische innovaties op dat moment: de entree van de boekdruk, telecommunicatie, computersystemen en virtuele realiteit. Binnenkort zullen we ingrijpende invloeden zien vanuit de biotechnologie, genetische modificatie, nanotechnologie etcetera. De huidige stap van laptop naar het veelkunnende mobieltje is er slechts één van de lange rij ICT-hulpmiddelen die er nog aan gaan komen. Als we de trend van ICT in onderwijs doortrekken, dan valt te verwachten dat 'mobiel leren' vooral zal leiden tot 'ubiquitous learning': overal- en voortdurend leren. Het begrip 'learning by heart' krijgt opnieuw betekenis: niet alleen het 'van buiten' leren, maar het opbouwen van een relatie met het onderwerp dat je bestudeert. De persoon van de docent wordt nog belangrijker dan hij nu al is. Mobiele communicatie gaat haar eerste vruchten afwerpen bij het 'voortdurend leren' van de docent. Het mobieltje en de on-line PDA gaan hierin een cruciale rol spelen. De Fontys lerarenopleidingen nemen met enthousiasme deze voortrekkersrol op zich. Het lectoraat Educatieve Functies van ICT begeleidt docenten en promovendi hierbij.

Walking meetings are a promising way to reduce unhealthy sedentary behavior at the office. Some aspects of walking meetings are however hard to assess using traditional research approaches that do not account well for the embodied experience of walking meetings. We conducted a series of 16 bodystorming sessions, featuring unusual walking meeting situations to engage participants (N=45) in a reflective experience. After each bodystorming, participants completed three tasks: a body map, an empathy map, and a rating of workload using the NASA-TLX scale. These embodied explorations provide insights on key themes related to walking meetings: material and tools, physical and mental demand, connection with the environment, social dynamics, and privacy. We discuss the role of technology and opportunities for technology-mediated walking meetings. We draw implications for the design of walking meeting technologies or services to account for embodied experiences, and the individual, social, and environmental factors at play.

Ubiquitous computing, new sensor technologies, and increasingly available and accessible algorithms for pattern recognition and machine learning enable automatic analysis and modeling of human behavior in many novel ways. In this introductory paper of the 6th International Workshop on Human Behavior Understanding (HBU’15), we seek to critically assess how HBU technology can be used for elderly. We describe and exemplify some of the challenges that come with the involvement of aging subjects, but we also point out to the great potential for expanding the use of ICT to create many applications to provide a better life for elderly.

Intelligent environments can offer support to people with early-stage dementia, who often experience problems with maintaining their circadian rhythm. The focus of this work is developing a prototype of an Intelligent Environment for assisting these people with their daily rhythm while living independently at home. Following the four phases of the Empathic Design Framework (Explore, Translate, Process, and Validate), the needs of people with dementia and their caregivers were incorporated into the design. In the exploration phase, a need assessment took place using focus groups (N=12), observations (N=10), and expert interviews (N=27). Then, to determine the requirements for a prototype of an intelligent environment, the second phase, Translate, used three co-creation sessions with different stakeholder groups. In these sessions, Mind Maps (N=55) and Idea Generation Cards (N=35) were used. These resulted in a set of 10 requirements on the following topics: context-awareness, pattern recognition, adaptation, support, personalization, autonomy, modularity, dementia proof interaction, costs, data, and privacy. Finally, in the third phase, the requirements were applied to a real-life prototype by a multidisciplinary design team of researchers, (E-Health) tech companies, designers, software engineers with representatives of eight organizations. The prototype serves as a basis for further development of Intelligent Environments to enable people with dementia to live longer independently at home.

In an aging population, the prevalence of people with dementia is increasing. Intelligent environments can offer a solution to support people in the early stages of dementia, who often experience problems with maintaining their day-night rhythm. The focus of this work is developing an Intelligent Environment for assisting these people with their daily structure while living independently at home. Three co-creation methods with several stakeholder groups were used to elicit requirements and develop a prototype of an Intelligent Environment. Participants were involved in sessions using Mind Maps (N=55), Idea Generation Cards (N=35), and in a multidisciplinary design team with representatives of eight organizations. The result of these sessions was a set of 10 requirements for the Intelligent Environment on the following topics: context-awareness, pattern recognition, adaptation, support, personalization, autonomy, modularity, dementia proof interaction, costs, data and privacy. Based on these requirements, several scenarios were developed to explicate such an environment for supporting people with early dementia. The design team translated the requirements to a real-life prototype of an Intelligent Environment integrated into a demonstration home. The prototype serves as a basis for further development of Intelligent Environments to enable people with dementia to live longer independently at home.

Elk jaar organiseert de HBO-I stichting, het samenwerkingsverband van hbo ict-opleidingen in Nederland, een conferentie voor haar leden. Tijdens deze conferenties staan strategisch beleid, deskundigheidsbevordering en samenwerking centraal. Sinds 2005 is de internationale oriëntatie als strategisch aspect benadrukt. De blik tien jaar vooruit om de curricula niet op hypes, maar op trends te sturen. In 2005 werd Silicon Valley bezocht en in 2006 ging het HBO-I naar de CeBit in Hannover. Dit jaar zochten we de ict-wijsheid in het verre oosten. Hoe ontwikkelt ict zich in Azië? Dat was de reden voor het HBO-I om een studiereis te maken naar Japan. In Tokyo tref je alle grote ict-bedrijven en drie van de beste Japanse universiteiten. Geen betere periode om Tokyo te bezoeken dan de week van de kersenbloesem. Een verslag van een indrukwekkende HBO-I studiereis naar Japan.
