  • Activity Recognition and Event Detection in Table Tennis
    (Own Funds)
    Digitalization of sports is also taking place in table tennis. This is caused by body-worn Wearables. This project captures, analyzes and processes the motion and movement of players,  ball characteristics and other interesting parameters during table tennis games and exercises. In contrast to common standard camera-based analysis within predefined laboratory environments used for most ball sports, only sensors mounted on the racket are included. All necessary electronics should ideally be hidden inside the racket, that the user does not feel affected. For motion analysis, mainly inertial sensors (accelerometers and gyroscopes) are used, as well as magnetometers for the absolute alignment in space and specific piezoelectric sensors for vibration detection. First, the acceleration, the angular velocity and absolute orientation of the racket are measured to classify the stroke type using pattern recognition algorithms.  It is possible to differentiate between forehand and backhand stroke types and various spin types. In addition, the ball impact event is verified by the vibration sensors. Afterwards, the resulting ball speed and spin are estimated shortly after this impact. Finally, the point of impact on the racket is localized by triangulation methods, similar to epicenter localization during earthquakes. All data is calculated on the embedded microcontroller and transferred to a mobile device, such as an Android smartphone via Bluetooth. There, the data is provided to the player as feedback for training support or statistics.
  • DailyHeart
    (Own Funds)
    Term: Aug 15, 2014 - Aug 15, 2017
    DailyHeart is a system for mobile ECG analysis that addresses the whole pipeline from data acquisition over data processing to data visualization. It features a novel low-power data acquisition ECG hardware using Bluetooth Low Energy, and an application for Android-based mobile devices that offers several modes for cardiac feedback, from measuring the current heart rate to continuously monitoring the user’s ECG throughout the day. Furthermore, it incorporates methods for human computer interaction concepts (e.g. smartwatches or Google Glass) to provide cardiac feedback to the user throughout the day, and depending on the current context.

    One clinical use case of DailyHeart is the unobtrusive monitoring of the users’ heart rate variability (HRV) by combining it with information on posture changes, e.g. changes from lying down to sitting or standing up. Initial results have shown that multiple measurements throughout the day can already indicate a possible disorder of the autonomous nervous system (e.g. Parkinson's Disease), and thus provide a recommendation of consulting a medical expert.

    Die Europäische Metropolregion Nürnberg (EMN) bietet eine weltweit einzigartige Konstellation für die industrienahe Forschung im Bereich eingebetteter Systeme für Sport- und Fitnessanwendungen. Das Lab Fitness@ESI wird breit aufgestellt. Es gilt sowohl Themen des Spitzen- und Breitensports zu bedienen, als auch Wege aufzuzeigen, zentrale Themen des stetig an Bedeutung gewinnenden Marktes für Sportmöglichkeiten behinderter Menschen zu erleichtern. Weiterhin werden Bereiche von der persönlichen Fitness bis hin zu Altersgerechten Anwendungen thematisiert. Damit können wichtige Märkte wie der für Imagegewinn und als Vorreiter wichtige Spitzensport und der finanziell attraktive Team- und Freizeitsport adressiert werden. Der Schwerpunkt soll dabei auf elektronischen Produkten im Fitness-Sektor (ähnlich zu bereits existierenden Produktfamilien wie Fitbit, iHealth, miCoach oder Nike+), Web-Plattformen und Anwendungsbeispielen liegen. Eine große Rolle werden in Zukunft auch Produkte für individualisierte Ratschläge und Trainingsempfehlungen spielen. Gerade der Bereich der personalisierten Fitness-Produkte zur Selbstkontrolle und -überwachung der eigenen Gesundheit und Fitness im Rahmen der „Quantified Self“-Bewegung hat ein enormes Marktpotenzial. Auch eine Erweiterung in den Bereichen Ambient Assisted Living (AAL) und Mobile Health (mHealth) ist denkbar.

    Die Kompetenzen der Partner sind ideal komplementär, um wichtige Themen des Labs Fitness@ESI angehen zu können. Mit der Kombination der Expertisen der FAU und des Fraunhofer IIS können die bereits jetzt vorliegenden Fragestellungen aus der Industrie angegangen werden. Diese beschäftigen sich u. a. mit Sensorintegration und Datenauswertung, um wichtige Events im Team- und Freizeitsport (Auswertung von Pässen oder Schüssen im Fußball für den Trainer, Vitalparameteranalyse von Läufern für den Breitensport) adressieren zu können. Des Weiteren sind Auswertungen von Positionsdaten von hohem Interesse für Vereine und Medien. Weitere technologische Inhalte des Projekts bewegen sich im Bereich der drahtlosen, körpernahen Sensornetzwerke. Wichtige Forschungsbereiche sind die sensorische Umgebungserfassung und -analyse, Energy Harvesting (Energiegewinnung) für batterie- und kabellose Energieversorgung, drahtlose Energieübertragung, Indoor- Lokalisierung und das Design von neuartigen, miniaturisierten Sensorknoten auf Niedrigenergiebasis. Ein weiterer wichtiger Punkt ist die unauffällige Integration von Sensorik in Kleidung, Schuhen, Sportgeräten und der Umgebung des Anwenders. Mögliche Anwendungen sind die automatische Erkennung sportspezifischer Bewegungen, automatisierte Trainingsunterstützung und Feedback-Anwendungen.

    Aus Sicht der Softwareentwicklung liegen die Herausforderungen unter anderem in der Echtzeitverarbeitung und Fusion von Sensorsignalen, der effizienten drahtlosen übertragung und dem gleichzeitigen ressourcenschonenden Umgang mit Energie und Speicher.

    Die nötigen Tests neu zu etablierender Systeme an realem Klientel (Elite- und Amateursportvereine, Freizeitsportler, aber auch ältere, sowie seh- oder gehbehinderte Menschen) sind über die etablierten sehr guten Kontakte zu Industrieunternehmen wie der adidas AG, dem Institut für Sportwissenschaft und Sport der FAU und dem Universitätsklinikum Erlangen sichergestellt.

  • Fall risk detection for Parkinson's disease via intelligent gait analysis
    (Third Party Funds Single)
    Term: Jan 1, 2018 - Dec 31, 2019
    Funding source: Bayerisches Staatsministerium für Wirtschaft und Medien, Energie und Technologie (StMWIVT) (ab 10/2013)
    The ability to walk defines human nature and limits the mobility, independence, and quality of life. Falls are the leading cause of both fatal and nonfatal injuries among older adults, causing severe injuries such as hip fractures, head trauma, and death. Increased fall risk is a key symptom in Parkinson’s disease (PD), limiting the independency and mobility of patients.

    So far, no validated technical solutions exist to identify the individual’s rising fall risk before the first fall occurs. Therefore, we will investigate algorithms, that are able to predict the fall risk based on specific gait patterns, captured by shoe integrated inertial sensors. The data for the evaluation of fall risk associated gait patterns will be acquired by means of a continuous long-term monitoring system.

    To ensure a successful progress of this project we will combine three strategies in the research and development phase:

    1. Usage of distinct sensors that enable gait assessment with high biomechanical resolution
    2. Development and evaluation of machine learning based gait pattern algorithms
    3. Digital biobanking of clinical distinct gait patterns to individualize fall risk monitoring.

    The overall goal of the project is the investigation of novel machine learning based algorithms that enable the determination of PD patients’ fall risk using continuous gait data. Since existing algorithms and test procedures in related clinical research are typically limited to one-time assessments, we will investigate new algorithms for a continuous gait monitoring system, that will identify disease specific changes of gait with a high reliability.

    At the same time, we will generate clinical understanding and validated data for individualized applicability that is required for medical product licensing, as well as economic effect sizes of technology application in healthcare strategies.

  • Green Belt ML@Operations - Machine Learning for Specific Use Cases in Production and Quality
    (Third Party Funds Single)
    Term: Nov 1, 2017 - Oct 31, 2019
    Funding source: Bundesministerium für Bildung und Forschung (BMBF)
    Die Digitalisierung birgt große Potenziale zur Steigerung der Ressourceneffizienz industrieller Produktionsprozesse. Durch Technologien im Kontext von Industrie 4.0 können produktionsnahe Daten kurzzyklisch erfasst und aggregiert werden. In Anbetracht der dadurch zunehmenden Datenkomplexität und des Datenvolumens stehen Mitarbeiter jedoch vor der Herausforderung, diese Daten zu analysieren und zu interpretieren sowie die Nachhaltigkeit der eingeleiteten Maßnahmen zu bewerten, wobei die kognitiven Fähigkeiten oft an ihre Grenzen stoßen.

    Verfahren des Maschinellen Lernens (ML) können hier neue Formen der Arbeitsteilung zwischen Maschinen bzw. Software als Entscheidungsvorbereiter und Mitarbeitern als Problemlöser zu ermöglichen. In der industriellen Praxis werden ML-Verfahren meist situativ und von Experten entwickelt eingesetzt, so dass der Aufwand entsprechend hoch ist. Des Weiteren verfügen kleine und mittlere Unternehmen (kmU) häufig nur über wenig Ressourcen und Expertise, um diese Potenziale zu nutzen.

    Ziel dieses Projektes ist es, ein Qualifizierungskonzept zu entwickeln und durchzuführen, um den Kenntnisstand bzgl. ML-Verfahren von Mitarbeitern in Produktions- und Qualitätsbereich sowie von Studierenden mit den genannten Schwerpunkten gezielt zu erweitern. Die Teilnehmer entscheiden sich dabei entweder für die Spezialisierungsrichtung "Produktion" oder "Qualität". Jede Spezialisierungsrichtung besteht aus vier praxisorientierten Anwendungsfällen, in denen die Teilnehmer geeignete ML-Verfahren kennenlernen und in konkreten individuellen Projekten mit ca. 10 Wochen Dauer anwenden. Die Anwendungsphase wird von der wissenschaftlichen Leitung des Projekts individuell gecoacht. Die Anwendungsfälle orientieren sich an bestehenden Geschäftsprozessen und Problemstellungen in der Industrie zum Qualitätsmanagement und zur Optimierung von Produktionsprozessen, wodurch ein einfacher Transfer und eine hohe Akzeptanz auf industrieller Seite sichergestellt werden soll.

    Body Sensor Networks are getting more and more important in sports and health. Currently, various isolated applications exist that use body sensors to assist athletes and monitor elderly people. Systems like the adidas miCoach and Nike+ prove the potential of information and communication engineering technology for manufacturers of sports equipment. The perfect product for a leading position in this market would be a central, flexible and generic wearable computing platform instead of isolated applications. To facilitate such a solution, sensors integration in clothing and sports equipment and data analysis capabilities have to be substantially advanced. Additionally, to succeed on the market, new communication and sensor technologies as well as innovative applications have to be developed.

    The goal of the project is to bundle and enhance the expertise of the project partners in the described field to develop innovative products. The existing miCoach platform will be the basis for a comprehensive communication and application platform for body sensor network data called "miLife". This platform will provide flexible sensor connection, data analysis and social networking capabilities for applications in team sports, exercise motivation and health monitoring.

    RoboCup is a international initiative to promote research in artificial intelligence and autonomous mobile robots. Each year the RoboCup Foundation hosts international tournaments where top research groups of Universities from the whole world participate. Since 2008, the University of Erlangen-Nuremberg also has its own RoboCup team that participates in the small-size league. This league is one of the smallest and fastest RoboCup leagues. Five wheeled robots per team are playing on a field of about 6m x 4m. The maximum size for each robot is 18cm in diameter and a height of 15 cm. The robots get information about the current game situation from two cameras above the field and an external computer, which communicates with the robots via a wireless link. In Erlangen the team is organized as an interdisciplinary student project at the Technical Department. The main goals of this project are to foster creative ideas and team work among technical students from electrical engineering, mechatronics and computer science. Research topics include topics from pattern recognition, embedded systems and artificial intelligence. In the scope of this project the Pattern Recognition Lab employs statistical estimation techniques and tries to extend them towards automotive applications. To promote the project, a non-profit organisation called "Robotics Erlangen e.V." was founded in 2008. In this organization team members as well as supporters of the group are brought together. The project is funded in part by tuition fees as well as private and industry donations.
