At the Public Health Congress "Poverty and Health", Birte Richter and Janna Landwehr from the Medical Assistance Systems working group presented the "Healthy in Baumheide" project in their presentation "Realising a participatory cooperation project for health promotion in university teaching - implementation, results and experiences from different perspectives".

In this interdisciplinary project, health scientists are working with computer scientists to develop a context-based health app for a neighbourhood in Bielefeld, in which local children are actively involved in the development process. Based on the work of various practice partners, the project is cooperating with school pupils from the local secondary school. The aim is to promote health through social interaction, learning about resources in the neighbourhood and encouraging physical activity.

In the subsequent discussion, the presented project was supplemented with the experiences from the plenary session and possible solutions were discussed. The aim was to jointly generate ideas for strengthening participation in cooperation projects in order to use these approaches to contribute to improving equal health opportunities.

"What is the best way to explain this to you?" To answer this question, we(SFB 318 project A03) investigated advice taking / rejecting during a risk decision in an online study with over 700 participants. For this purpose, the virtual robot Floka was used as an AI-supported decision support system. Four different explanations were analysed against each other. These were abstracted both from human-human interaction and from XAI. In addition to the different behaviour in the explanations, the quality of the advice, trust and satisfaction with Floka were also surveyed and evaluated.

These research results have been published in the journal "Frontiers in Behavioural Economics Culture and Ethics".

On 2 February 2014, the showroom of the Medical Assistance Systems and Interactive Robotics working groups was officially opened together with colleagues and friends.

In the showroom "interactive assistance in medicine
and care"
in the premises of the Faculty of Medicine, high-tech assistance systems can be experienced. In addition to commercial products,
also presents current research prototypes in changing exhibitions.

The aim of the showroom is to familiarise people with a wide range of different technical support systems, to enable them to try them out and thus, among other things, to break down barriers.


In future, changing exhibits on the areas of "prevention", "everyday assistance", "rehabilitation and therapy" will be on display. The aim is to provide insights into the explainability of decision support systems and the development of prototypes by means of co-design.

Study participants wanted!

Open source software "RISE" to simplify human-robot interaction studies

06/12/2023

The interdisciplinary scenario development of human-robot interaction (HRI) studies often requires repeated realisations of basic implementations. This leads to delays in progress and distracts the focus from new aspects in the field of HRI.

To facilitate the development of scenarios for human-robot interaction studies, it is necessary to standardise and generalise repeated standard implementations. RISE was developed for precisely this reason and serves as a platform to enable interdisciplinary teams to improve the exchange of information when developing HRI scenarios. Clear, comprehensible files for defining scenarios not only make it much easier to create studies on human-robot interaction, but also to reproduce them.

RISE also offers a sophisticated graphical user interface (GUI). This allows internal states to be monitored and behaviour to be adjusted manually. This not only enables fully autonomously controlled behaviour, but also so-called "Wizard of Oz" studies. Here, the human can dynamically adapt the robot's behaviour to the respective situation in the background during the study. The expandability of RISE for external sensors and new robots also opens up a wide range of possibilities for various studies.

The open-source architecture and software RISE(GitLab project) are presented in detail in the journal"Frontiers in Robotics and AI". The system includes extensive documentation and addresses various problems that occur in existing software solutions for the development of human-robot interactions.

The development took place as part of the SFB/TRR 318 "Constructing Explainability".

A new publication in the journal "Frontiers in Robotics and AI" promises interesting results in the field of human-robot interaction. The research team A05 of the SFB/TRR 318, has published an article with the title "Scaffolding the human partner by contrastive guidance in an explanatory human-robot dialogue".

The research investigates the use of negation as a guiding strategy in interactive communication between humans and robots. An empirical study showed that while the use of negation led to longer reaction times compared to affirmation, it also improved task performance in several aspects. The results of this study shed light on the effects of negation on the linguistic processing of explanations in human-robot interaction.

Joint Research Centre explores key issue for the future related to co-constructive artificial intelligence

10/07/2023

The universities of Bielefeld University, Paderborn and Bremen have joined forces to develop AI systems that will support humans in carrying out everyday tasks.

For this purpose, researchers from the fields of AI, robotics, human-computer interaction, medical assistance, linguistics, psychology and sociology are working together in the newly founded Joint Research Center and creating the basis for the development of new robots with completely new capabilities. The basis of the research lies in the ability of a robot to learn through interaction with humans.

Based on this knowledge, the Researchers explore conceptual frameworks for intelligent action: The concept of so-called co-construction refers to cognitive and interactive mechanisms that help humans and machines to accomplish tasks together.

By founding the Joint Research Centre, the expertise on co-constructive AI from no less than three research locations will be combined in one hub. Further information...
