(2018): The use of assistive technologies after stroke is debunking the myths about the elderly. In: Topics in stroke rehabilitation 25 (1), S. 28-36. DOI: 10.1080/10749357.2017.1376845
DOI: https://doi.org/10.1080/10749357.2017.1376845 Abstract: Background Through the concept of ageism, we highlight and explain how the society prejudices the elderly. WHO classifies 12 most common stereotypes pertaining to old age. Elderly people are being excluded from social life due to their chronological age rather than any actual reduced physical and/or mental ability. Some of these stereotypes are directly related to the (un)willingness and the ability of the elderly to use technology in everyday life. Objectives The study presented in this article aims to explain the phenomenon of technology use among elderly people who had had a stroke. Method A qualitative study, namely a qualitative content analysis, was performed. Six in-depth interviews with older people who have suffered a stroke were conducted and explored their views on the daily use of technology. Results All older people included in this study used different technologies, which have been divided into technologies that support mobility, technologies for personal care, technologies that support household chores, and technologies for maintaining a social network. An elderly person's attitude toward the use of technology is connected to their social network and assistance from professional staff, as well as the severity of their physical disability. We have found that using various technologies, elderly people are developing various coping strategies. Conclusions After a stroke, a certain degree of physical deterioration can be expected. Nonetheless, our participants managed to compensate for this also with the help of assistive devices and technologies, which negates the myth of simply "surrendering" to the aging process.

(2017): A population study of correlates of social participation in older adults with age-related vision loss. In: Clinical rehabilitation 31 (1), S. 115-125. DOI: 10.1177/0269215515624479
DOI: http://journals.sagepub.com/doi/pdf/10.1177/0269215515624479 Abstract: OBJECTIVE To examine personal characteristics, disease-related impairment variables, activity limitations, and environmental factors as correlates of social participation in older adults with vision loss guided by the World Health Organization's International Classification of Functioning, Disability and Health Model. DESIGN Baseline data of a larger longitudinal study. SETTING Community-based vision rehabilitation agency. SUBJECTS A total of 364 older adults with significant vision impairment due to age-related macular degeneration. MAIN MEASURES In-person interviews assessing social participation (i.e. frequency of social support contacts, social/leisure challenges faced due to vision loss, and of social support provided to others) and hypothesized correlates (e.g. visual acuity test, Functional Vision Screening Questionnaire, ratings of attachment to house and neighborhood, environmental modifications in home). RESULTS Regression analyses showed that indicators of physical, social, and mental functioning (e.g. better visual function, fewer difficulties with instrumental activities of daily living, fewer depressive symptoms) were positively related to social participation indicators (greater social contacts, less challenges in social/leisure domains, and providing more support to others). Environmental factors also emerged as independent correlates of social participation indicators when functional variables were controlled. That is, participants reporting higher attachment to their neighborhood and better income adequacy reported having more social contacts; and those implementing more environmental strategies were more likely to report greater challenges in social and leisure domains. Better income adequacy and living with more people were related to providing more social support to others. CONCLUSION Environmental variables may play a role in the social participation of older adults with age-related macular degeneration.

(2017): Online Recognition of Daily Activities by Color-Depth Sensing and Knowledge Models. In: SENSORS 17 (7)
Abstract: Visual activity recognition plays a fundamental role in several research fields as a way to extract semantic meaning of images and videos. Prior work has mostly focused on classification tasks, where a label is given for a video clip. However, real life scenarios require a method to browse a continuous video flow, automatically identify relevant temporal segments and classify them accordingly to target activities. This paper proposes a knowledge-driven event recognition framework to address this problem. The novelty of the method lies in the combination of a constraint-based ontology language for event modeling with robust algorithms to detect, track and re-identify people using color-depth sensing (Kinect® sensor). This combination enables to model and recognize longer and more complex events and to incorporate domain knowledge and 3D information into the same models. Moreover, the ontology-driven approach enables human understanding of system decisions and facilitates knowledge transfer across different scenes. The proposed framework is evaluated with real-world recordings of seniors carrying out unscripted, daily activities at hospital observation rooms and nursing homes. Results demonstrated that the proposed framework outperforms state-of-the-art methods in a variety of activities and datasets, and it is robust to variable and low-frame rate recordings. Further work will investigate how to extend the proposed framework with uncertainty management techniques to handle strong occlusion and ambiguous semantics, and how to exploit it to further support medicine on the timely diagnosis of cognitive disorders, such as Alzheimer’s disease.

(2017): Toward an intelligent long-term assistance for people with dementia in the context of navigation in indoor environments : Intelligente Langzeit-Unterstützung für Menschen mit Demenz im Kontext der Navigation in Gebäuden. In: Universität Würzburg, Graduate School of Science and Technology
Abstract: Designed and examined a system for indoor environments for people with moderate to severe dementia, who are unable or reluctant to use smartphone technology. To this end, a series of 10 studies was conducted with total of 35 adults with dementia. In the first step, a user-centered design approach was adopted to gather context and requirements of people with dementia in order to understand needs and difficulties (especially in spatial disorientation and wayfinding problems) experienced in dementia care facilities. Then, an "Implicit Interactive Intelligent (III) Environment" for people with dementia was proposed emphasizing implicit interaction and natural interface. The backbone of this III Environment is based on supporting orientation and navigation tasks with three systems: a monitoring system, an intelligent system, and a guiding system. The monitoring system and intelligent system automatically detect and interpret the locations and activities performed by the users i.e. people with dementia. This approach (implicit input) reduces cognitive workload as well as physical workload on the user to provide input. The intelligent system is also aware of context, predicts next situations (location, activity), and decides when to provide an appropriate service to the users. The guiding system with intuitive and dynamic environmental cues (lighting with color) has the responsibility for guiding the users to the places they need to be. Overall, three types of a monitoring system with Ultra-Wideband and iBeacon technologies, different techniques and algorithms were implemented for different contexts of use. They showed a high user acceptance with a reasonable price as well as decent accuracy and precision. In the intelligent system, models were built to recognize the users' current activity, detect the erroneous activity, predict the next location and activity, and analyze the history data, detect issues, notify them and suggest solutions to caregivers via visualized web interfaces. Regarding the guiding systems, five studies were conducted to test and evaluate the effect of lighting with color on people with dementia. The results were promising. Although several components of III Environment in general and three systems, in particular, are in place (implemented and tested separately), integrating them all together and employing this as a fully properly evaluation with formal stakeholders (people with dementia and caregivers) need to be examined in future research.

(2016): Sollten Assistenzroboter eine "Persönlichkeit" haben? : Potenzial simplifizierter Roboterpersönlichkeiten. In: Zeitschrift fur Gerontologie und Geriatrie 49 (4), S. 298-302. DOI: 10.1007/s00391-016-1068-3
DOI: http://www.ncbi.nlm.nih.gov/pubmed/27245227 Abstract: BACKGROUND In the European Union (EU) research project "HOBBIT" prototypes of assistive robots were developed in order to support a more secure and independent life style and trials were run at the homes of elderly users. OBJECTIVE The project "personAAL" aimed at investigating whether distinct behavioral forms of a robot ("personality"), despite an identical basic function (e.g. bringing a message) are perceived as different personalities by the test persons. MATERIAL AND METHODS For this study a robot was equipped with two types of behavior, one more introverted (purely function-oriented, impersonal and factual) and the other more extroverted (lively and enriched). The two types of behavior were demonstrated to 13 test persons (mostly older persons and experts from the care domain). RESULTS Nearly all of the test persons (12 out of 13) perceived a difference with respect to the behavior of the robot. Of the test persons 1 preferred the introverted robot, 9 the extroverted behavior of the robot and 3 had no preferences or stated that the preference depended on the context. The evaluation of answers to the Godspeed questionnaire resulted in significantly different perceptions of "anthropomorphism" and "animated" as well as in the total evaluation. It is also remarkable that no significant differences could be found for "likeability" and "perceived security". There was also no significant correlation between the preferred behavior of the robot and the self-assessment of the test person as being more introverted or extroverted. CONCLUSION From these results it can be concluded that acceptance of a robot does not solely depend on the mere function, which of course is a precondition but that it is advisable to offer a choice between different types of behavior in order to optimize acceptance.

(2010): DEEPKOVER – AN ADAPTIVE ARTFUL INTELLIGENT ASSISTANCE SYSTEM FOR COGNITIVELY IMPAIRED PEOPLE. In: Applied Artificial Intelligence 24 (5), S. 381-413. DOI: 10.1080/08839514.2010.481486
DOI: https://doi.org/10.1080/08839514.2010.481486 Abstract: This article presents a novel modular adaptive artful intelligent assistance system for cognitively and/or memory impaired people engaged in the realization of their activities of daily living (ADLs). The goal of this assistance system is to help disabled persons moving/evolving within a controlled environment in order to provide logistic support in achieving their ADLs. Empirical results of practical tests are presented and interpreted. Some deductions about the key features that represent originalities of the assistance system are drawn and future works are announced. (PsycINFO Database Record (c) 2016 APA, all rights reserved)

(2005): Gewohnheiten im Alter. In: Psychotherapie im Alter 2 (2), S. 9-20
Abstract: Vor dem Hintergrund eines "gesundheitspolitischen Managements von Gewohnheiten im Alter" wird die Bedeutung der zukunftigen Einubung und Stabilisierung von Gewohnheiten bei alteren Menschen mit Blick auf widerspruchliche Haltungen erortert. Gewohnheiten und ihre Verfestigungen zu Ritualen sind Ausdruck des Alltagslebens und helfen es gleichzeitig zu strukturieren. Sie vermitteln uber die ihnen innewohnenden Wiederholungen Handlungssicherheit und Berechenbarkeit. Wenn sie entfallen, werden zwar neue Freiheitsraume erfahrbar, doch steigert sich auch die Komplexitat der Erfordernisse zum Handeln. Gewohnheiten im hoheren Lebensalter werden deutlich kritischer bewertet und mit traditionellen Stereotypen des Alters verbunden. Da sich in Zukunft die Erfahrungswelten fur das hohere Lebensalter deutlich ausweiten werden, ist eine Vielzahl von Altersgewohnheiten zu erwarten, fur die traditionelle Ordnungsmuster alleine keine Aussagekraft mehr besitzen.
