Bericht zur Bedarfsanalye
Wie können Roboter im Krankenhaus- und Pflegesektor Werte schaffen?
Wir schauen in eine Zukunft, wo viele Bürger pflegebedürftig werden, und zu wenige da sein werden, um die Pflege durchzuführen.
Endprodukt des Health-CAT Projektes ist ein Roboterprototyp, der dazu beiträgt, die demographische Herausforderung zu erleichtern. Um zu untersuchen, wie dies gemacht werden kann, nimmt das Projekt seinen Ausgangspunkt in einer sorgfältigen Bedarfsanalyse.
Wissenschaft:Stereo and Active-Sensor Data Fusion for Improved Stereo Block Matching
This paper proposes an algorithm which uses the depth information acquired from an active sensor as guidance for a block matching stereo algorithm. In the proposed implementation, the disparity search interval used for the block matching is reduced around the depth values obtained from the active sensor, which leads to an improved matching quality and denser disparity maps and point clouds. The performance of the proposed method is evaluated by carrying out a series of experiments on 3 different data sets obtained from different robotic systems. We demonstrate with experimental results that the disparity estimation is improved and denser disparity maps are generated.
Wissenschaft: I Would Like to Get Close to You“: Making Robot Personal Space Invasion Less Instructive with a Social Gaze Cue
How can a social robot get physically close to the people it needs to interact with? We investigated the effect of a social gaze cue by a human-sized mobile robot on the effects of personal space invasion by that robot. In our 2××2 between-subject experiment, our robot would approach our participants (n = 83), with/without personal space invasion, and with/without a social gaze cue. With a questionnaire, we measured subjective perception of warmth, competence, and comfort after such an interaction. In addition, we used on-board sensors and a tracking system to measure the dynamics of social positioning behavior. While we did find significant differences in the social positioning dynamics of the participants, no such effect was found upon quantitative analysis of perception of the robot. In a subsequent inductive analysis we further investigated these results, our findings suggesting that the social cue did play a role for the participants – particularly related to their perceived safety.
Wissenschaft: Increasing trust in human–robot medical interactions: effects of transparency and adaptability
In this paper, we examine trust in a human-robot medical interaction. We focus on the influence of transparency and robot adaptability on people’s trust in a human-robot blood pressure measuring scenario. Our results show that increased transparency, i.e. robot explanations of its own actions designed to make the process and robot behaviors and capabilities accessible to the user, has a consistent effect on people’s trust and perceived comfort. In contrast, robot adaptability, i.e., the opportunity to adjust the robot’s position according to users’ needs, influences users’ evaluations of the robot as trustworthy only marginally. Our qualitative analyses indicate that this is due to the fact that transparency and adaptability are complex factors; the investigation of the interactional dynamics shows that users have very specific needs, and that adaptability may have to be paired with responsivity in order to make people feel in control.
Wissenschaft: Robot technology for future welfare: meeting upcoming societal challenges – an outlook with offset in the development in Scandinavia
In many countries, a demographic change has been recognized and is subject to public discussions, either directly or indirectly by social systems being challenged with the growing demands. However, with the increase of life expectancy, also the type of needs change due to an increase of co-morbidity and multi-chronic conditions asking for an increased focus on the patient as a whole rather than the individual diseases. Recent technological advances provide new opportunities for technical solutions that interact with end users and the utilization of robots is considered one potential mean for addressing this challenge. This article outlines the changes in the demands, with particular examples taken from the Danish health care system as an example, together with the technological achievements within the robotics domain. We identify where technologies that to a large degree are existing already today can be utilized to support the social systems in the near future. We show that several of the challenges related to the demographic change can be addressed with technology that is already available and that for some cases have reached the mass market already. We also outline the to be expected opportunities and challenges in the development of future robots in the health-care domain.
Wissenschaft: Robot use cases for real needs: A large-scale ethnographic case study
This article discusses the process of developing robot use cases using large-scale ethnographic observation as a starting point. In particular, during 296 hours of ethnographic observation of the workflows at seventeen departments at Odense University Hospital, 607 processes were described and subsequently annotated. The ethnographic method provided rich, contextually situated data that can be searched and categorized for use case development, which is illustrated on an example use case, describing the process and illustrating the type of data elicited, discussing the problems encountered and providing downloadable tools for other researchers interested in similar approaches to use case development.
