- Activity Recognition and Event Detection in Table Tennis
(Own Funds)Term: Jan 1, 2015 - Jan 1, 2018
URL: https://www.mad.tf.fau.de/research/projects/esifitness/activity-recognition-and-event-detection-in-table-tennis/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.
(Own Funds)Term: Aug 15, 2014 - Aug 15, 2017DailyHeart 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.

- Digital Sports Bavaria: Implementation and validation of innovative Cyber Physical Systems and Human Computer Interaction concepts for future Wearable Computing trends in sport and fitness
(Third Party Funds Single)Term: Apr 1, 2015 - Mar 31, 2018
Funding source: Bayerisches Staatsministerium für Wirtschaft und Medien, Energie und Technologie (StMWIVT) (ab 10/2013)Digitalization becomes more and more part of different areas in daily life, e.g. sports and fitness: Wearables, nowadays especially step counters or activity trackers, support humans by individual promotion of health and improvement of fitness. Due to the various application areas, these Wearables are a profitable market for the future, but current existing systems have the following disadvantages:
Currently available sensors on the market are external devices which are manually put into apparel. An incorrect use, based on wrong placement of the system, leads e.g. to movement patterns of steps which deviate from a usual step. This deviation is a challenge for further processing.
Signal analysis is mainly based on the classification of movements, e.g. the detection of steps. In many applications, the quality of movement is important. Based on the information about, how a step is performed, an assessment of e.g. the state of health of a person can be performed.
The user interfaces are mainly based on simple text and/or graphical output on mobile devices or PC, e.g. number of steps per day and during one week. Nevertheless, for long-term success of systems, innovative approaches are needed.
Wearables mainly communicate with mobile devices, e.g. smartphones or a PC. Data are transmitted to a server via web browser for storage and display. This kind of system architecture is called wireless sensor network. In many applications, this simple system architecture is not sufficient. Furthermore, the user pays a fixed amount of money for the complete system, independent of the usage of e.g. server and services. For more complex algorithms and a location-independent application of the system, other system architectures have to be used. Computationally intensive algorithms for step segmentation, which e.g. are combined with a comparison of steps and statistics from a database, should run directly on a remote server. Furthermore, it is proposed that the cost of the system should be dependent on the usage of server and services.
The goal of the project is to develop a generic platform for future Wearable Computing trends in sports and fitness, which has the following four features: (i) permanent availability by integrated sensors in apparel using e-textiles (sensor integration), (ii) intelligent and flexibly adaptable sensor data processing for a detailed analysis of complex movement patterns, which provides more than just a classification (signal analysis), (iii) development of innovative user interfaces (Human Computer Interaction), and (iv) extension of the system architecture of wireless sensor networks with a combination of cloud computing methods (Cyber Physical Systems).

- 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:
- Usage of distinct sensors that enable gait assessment with high biomechanical resolution
- Development and evaluation of machine learning based gait pattern algorithms
- 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.
