In this paper we present the concept of the "KI-Labor Südbaden" to support regional companies in the use of AI technologies. The approach is based on the "Periodic Table of AI" and is extended with both new dimensions for sustainability, and the impact of AI on the working environment. It is illustrated on the basis of three real-world use cases: 1. The detection of humans with lowresolution infrared (IR) images for collaborative robotics; 2. The use of machine data from specifically designed vehicles; 3. State-of-the-art Large Language Models (LLMs) applied to internal company documents. We explain the use cases, thereby demonstrating how to apply the Periodic Table of AI to structure AI applications.
Due to the increasing aging of the population, the number of elderly people requiring care is growing in most European countries. However, the number of caregivers working in nursing homes and on daily care services is declining in countries like Germany or Italy. This limits the time for interpersonal communication. Furthermore, as a result of the Covid-19 pandemic, social distancing during contact restrictions became more important, causing an additional reduction of personal interaction. This social isolation can strongly increase emotional stress. Robotic assistance could contribute to addressing this challenge on three levels: (1) supporting caregivers to respond individually to the needs of patients and residents in nursing homes; (2) observing patients’ health and emotional state; (3) complying with high hygiene standards and minimizing human contact if required. To further the research on emotional aspects and the acceptance of robotic assistance in care, we conducted two studies where elderly participants interacted with the social robot Misa. Facial expression and voice analysis were used to identify and measure the emotional state of the participants during the interaction. While interpersonal contact plays a major role in elderly care, the findings reveal that robotic assistance generates added value for both caregivers and patients and that they show emotions while interacting with them.
The automatic processing of handwritten forms remains a challenging task, wherein detection and subsequent classification of handwritten characters are essential steps. We describe a novel approach, in which both steps - detection and classification - are executed in one task through a deep neural network. Therefore, training data is not annotated by hand, but manufactured artificially from the underlying forms and yet existing datasets. It can be demonstrated that this single-task approach is superior in comparison to the state-of-the-art two task approach. The current study focuses on hand-written Latin letters and employs the EMNIST data set. However, limitations were identified with this data set, necessitating further customization. Finally, an overall recognition rate of 88.28% was attained on real data obtained from a written exam.
Im Rahmen des Forschungsprojekts Professional UX entwickelt die Hochschule Offenburg gemeinsam mit dem Softwarehaus Dr. Hornecker in Freiburg eine innovative Systemlösung, die es ermöglicht, anhand von Mimik, Stimme und Blickverlauf beim Nutzer entstehende Emotionen bei der Nutzung interaktiver Anwendungen zu erfassen und zu interpretieren. Ziel der Untersuchung ist es, Indikatoren zu identifizieren, die eine exakte Zuordnung von wahrgenommenen Reizen zu den jeweils ausgelösten Emotionen erlauben. Sobald negative Emotionen wie Ärger oder Unsicherheit auftreten, kann dieser erfasst und im Nachgang der jeweils irritierende Reiz eliminiert werden. Das Projektteam hat einen ersten Prototyp für die Professional UX Systemlösung in Form von Hard- und Software entwickelt, mit dem es möglich ist, UX-Messungen während der User Interaktion durchzuführen und automatisiert mithilfe von KI auswerten zu lassen.
