Medica 2021: Better posture at the workplace thanks to new sensor technology

Whether pain in the back, shoulders or knees: Incorrect posture in the workplace can have consequences. A sensor system developed by researchers at the German Research Centre for Artificial Intelligence (DFKI) and TU Kaiserslautern might be of help. Sensors on the arms, legs and back, for example, detect movement sequences and software evaluates the data obtained. The system provides the user with direct feedback via a Smartwatch so that he can correct movement or posture. The sensors could be installed in working clothes and shoes. The researchers have presented this technology at the medical technology trade fair Medica held from November 15th to 18th, 2021 at the Rhineland-Palatinate research stand (hall 3, stand E80).

Assembling components in a bent posture, regularly putting away heavy crates on shelves or quickly writing an e-mail to a colleague on the computer – during work most people do not pay attention to an ergonomically sensible posture or a gentle sequence of movements. This can result in back pain that may well occur several times a month or week and develop into chronic pain over time. However, incorrect posture can also lead to permanent pain in the hips, neck or knees.

A technology currently being developed by a research team at DFKI and Technische Universität Kaiserslautern (TUK) can provide a remedy in the future. Sensors are used that are simply attached to different parts of the body such as arms, spine and legs. “Among other things, they measure accelerations and so-called angular velocities. The data obtained is then processed by our software,” says Markus Miezal from the wearHEALTH working group at TUK. On this basis, the software calculates motion parameters such as joint angles at arm and knee or the degree of flexion or twisting of the spine. “The technology immediately recognizes if a movement is performed incorrectly or if an incorrect posture is adopted,” continues his colleague Mathias Musahl from the Augmented Vision/Extended Reality research unit at the DFKI.

The Smartwatch is designed to inform the user directly in order to correct his movement or posture. Among other things, the researchers plan to install the sensors in work clothing and shoes. This technology is interesting, for example, for companies in industry, but it can also help to pay more attention to one’s own body in everyday office life at a desk.

All of this is part of the BIONIC project, which is funded by the European Union. BIONIC stands for “Personalized Body Sensor Networks with Built-In Intelligence for Real-Time Risk Assessment and Coaching of Ageing workers, in all types of working and living environments”. It is coordinated by Professor Didier Stricker, head of the Augmented Vision/Extended Reality research area at DFKI. The aim is to develop a sensor system with which incorrect posture and other stresses at the workplace can be reduced.

In addition to the DFKI and the TUK, the following are involved in the project: the Federal Institute for Occupational Safety and Health (BAuA) in Dortmund, the Spanish Instituto de Biomechanica de Valencia, the Fundación Laboral de la Construcción, also in Spain, the Roessingh Research and Development Centre at the University of Twente in the Netherlands, the Systems Security Lab at the Greek University of Piraeus, Interactive Wear GmbH in Munich, Hypercliq IKE in Greece, ACCIONA Construcción S.A. in Spain and Rolls-Royce Power Systems AG in Friedrichshafen.

GreifbAR Projekt – Greifbare Realität – Interaktion mit realen Werkzeugen in Mixed-Reality Welten

Am 01.10.2021 ist das Forschungsprojekt Projekt GreifbAR gestartet unter Leitung des DFKI (Forschungsbereich Erweiterte Realität). Ziel des Projekts GreifbAR ist es, Mixed-Reality Welten (MR), einschließlich virtueller (VR) und erweiterter Realität („Augmented Reality“ – AR), greifbar und fassbar zu machen, indem die Nutzer mit bloßen Händen mit realen und virtuellen Objekten interagieren können. Die Genauigkeit und Geschicklichkeit der Hand ist für die Ausführung präziser Aufgaben in vielen Bereichen von größter Bedeutung, aber die Erfassung der Hand-Objekt-Interaktion in aktuellen MR-Systemen ist völlig unzureichend. Derzeitige Systeme basieren auf handgehaltenen Controllern oder Erfassungsgeräten, die auf Handgesten ohne Kontakt mit realen Objekten beschränkt sind. GreifbAR löst diese Einschränkung, indem es ein Erfassungssystem einführt, das sowohl die vollständige Handhalterung inklusiv Handoberfläche als auch die Objektpose erkennt, wenn Benutzer mit realen Objekten oder Werkzeugen interagieren. Dieses Erfassungssystem wird in einen Mixed-Reality-Trainingssimulator integriert, der in zwei relevanten Anwendungsfällen demonstriert wird: industrielle Montage und Training chirurgischer Fertigkeiten. Die Nutzbarkeit und Anwendbarkeit sowie der Mehrwert für Trainingssituationen werden gründlich durch Benutzerstudien analysiert.

XR for nature and environment survey

On July 29th, 2021, Dr. Jason Rambach presented the survey paper “A Survey on Applications of Augmented, Mixed and Virtual Reality for Nature and Environment” at the 23rd Human Computer Interaction Conference HCI International. The article is the result of a collaboration between DFKI, the Worms University of Applied Sciences and the University of Kaiserslautern.

Abstract: Augmented, virtual and mixed reality (AR/VR/MR) are technologies of great potential due to the engaging and enriching experiences they are capable of providing. However, the possibilities that AR/VR/MR offer in the area of environmental applications are not yet widely explored. In this paper, we present the outcome of a survey meant to discover and classify existing AR/VR/MR applications that can benefit the environment or increase awareness on environmental issues. We performed an exhaustive search over several online publication access platforms and past proceedings of major conferences in the fields of AR/VR/MR. Identified relevant papers were filtered based on novelty, technical soundness, impact and topic relevance, and classified into different categories. Referring to the selected papers, we discuss how the applications of each category are contributing to environmental protection and awareness. We further analyze these approaches as well as possible future directions in the scope of existing and upcoming AR/VR/MR enabling technologies.

Presseberichte zu unserem Projekt “KI-Rebschnitt”
Advancing sports analytics to coach athletes through Deep Learning research

The recent advancements in Deep learning has lead to new interesting applications such as analyzing human motion and activities in recorded videos. The analysis covers from simple motion of humans walking, performing exercises to complex motions such as playing sports.

The athlete’s performance can be easily captured with a fixed camera for sports like tennis, badminton, diving, etc. The large availability of low cost cameras in handheld devices has further led to common place solution to record videos and analyze an athletes performance. Although the sports trainers can provide visual feedback by playing recorded videos, it is still hard to measure and monitor the performance improvement of the athlete.  Also, the manual analysis of the obtained footage is a time-consuming task which involves isolating actions of interest and categorizing them using domain-specific knowledge. Thus, the automatic interpretation of performance parameters in sports has gained a keen interest.

Competitive diving is one of the well recognized aquatic sport in Olympics in which a person dives from a platform or a springboard and performs different classes of acrobatics before descending into the water. These classes are standardized by international organization Fédération Internationale de Natation (FINA). The differences in the acrobatics performed in various classes of diving are very subtle. The difference arises in the duration which starts with the diver standing on a diving platform or a springboard and ends at the moment he/she dives into the water. This is a challenging task to model especially due to involvement of rapid changes and requires understanding of long-term human dynamics. Further, the model must be sensitive to subtle changes in body pose over a large number of frames to determine the correct classification.

In order to automate this kind of task, three challenging sub-problems are often encountered:  1) temporally cropping events/actions of interest from continuous video;  2) tracking the person of interest even though other divers and bystanders may be in view; and 3) classifying the events/actions of interest.

We are developing a solution in co-operation with Institut für Angewandte Trainingswissenshaft in Leipzig (IAT) to tackle the three subproblems. We work towards a complete parameter tracking solution based on monocular markerless human body motion tracking using only a mobile device (tablet or mobile phone) as training support tool to the overall diving action analysis. The techniques proposed, can be generalized to video footage recorded from other sports.
