TL;DR: BLExpo, a beacon based service developed for an enhanced user experience at expo’s, relays location sensitive information saved on a server to the consumer, depending on his location, is described in this thesis in detail.
Abstract: The new Bluetooth 4.0 low energy (Bluetooth Smart) specification provides developers a means to create unique and never before seen systems. Using low energy beacons, new systems are able to deliver location based information to the user, whenever it comes into close proximity of a certain beacon. BLExpo, a beacon based service developed for an enhanced user experience at expo’s, relays location sensitive information saved on a server to the consumer, depending on his location, is described in this thesis in detail. Adapting the design of the service, a vast variety of different systems can emerge, and existing ones improved, by supplying beacons. A brief look at how Bluetooth low energy can make our lives more convenient is provided, as well as the issues that might arise when dealing with beacon based systems. Alternative designs are taken into account by describing systems that rely purely on Bluetooth low energy for both event triggering, and information exchange. Since every system mentioned in this thesis uses Bluetooth LE as the underlaying technology, it is also introduced and a brief overview is provided.

TL;DR: In this paper, a real-world business application scenario in the field of well-being and fitness is presented, in which two different sensors are integrated in a fitness application, in order to deal with problems relating to the connection and communication between the smart mobile device and the external sensors.
Abstract: Today, sensors are increasingly used for data collection. In the medical domain, for example, vital signs (e.g., pulse or oxygen saturation) of patients can be measured with sensors and used for further processing. In this paper, different types of applications will be discussed whether sensors might be used in the context of these applications and their suitability for applying external sensors to them. Furthermore, a system architecture for adding sensor technology to respective applications is presented. For this purpose, a real-world business application scenario in the field of well-being and fitness is presented. In particular, we integrated two different sensors in our fitness application. We report on the lessons learned from the implementation and use of this application, e.g., in respect to connection and data structure. They mainly deal with problems relating to the connection and communication between the smart mobile device and the external sensors, as well as the selection of the appropriate type of application. Finally, a robust sensor framework, arising from this fitness application is presented. This framework provides basic features for connecting sensors. Particularly, in the medical domain, it is crucial to provide an easy to use toolset to relieve medical staff.

TL;DR: In this paper, a Softwaresystem soll beispielsweise das Auffinden und Einsehen von Patientenakten and Aufgabenubersichten anhand von Kontexten optimieren, die durch die momentane Position eines Benutzers and seiner Zugehorigkeit zu einer Organisationseinheit bestimmt werden.
Abstract: Ziel der Arbeit ist es, einen weitreichenden Uberblick uber einige auf mobilen Endgeraten verfugbare physische Sensoren zu geben und ihre Verwendung zur Bestimmung des Kontexts eines Benutzers aufzuzeigen. Der Schwerpunkt vorgestellter physischer Sensoren wird auf denen liegen, die zur Positionsbestimmung des Benutzers herangezogen werden konnen. Darauf aufbauend werden Szenarien und Geschaftsprozessen erlautert, die durch den Einsatz mobiler Sensorik optimiert und automatisiert werden. Das Ziel, einen tiefen Einblick in die Kombination von Geschaftsprozessen mit Geschaftsanwendungen und mobiler Sensorik zu geben, wird durch die Implementierung eines Krankenhaus-Prozesses erreicht. Anhand des Prozesses und seiner Implementierung soll dargestellt werden, wie unter Verwendung von Bluetooth LE, Apples iOS, einer Serverarchitektur und zusatzlichen Komponenten eine Context Aware Application Geschaftsprozesse optimieren und automatisieren kann. Das resultierende Softwaresystem soll beispielsweise das Auffinden und Einsehen von Patientenakten und Aufgabenubersichten anhand von Kontexten optimieren, die durch die momentane Position eines Benutzers und seiner Zugehorigkeit zu einer Organisationseinheit bestimmt werden. Auch fehlerhafte Patientenverlegungen sollen durch die Anwendung verhindert und Medikamentenbestande einzelner Medikamente automatisiert dokumentiert und aktualisiert werden. Fur die Umsetzung einer solchen Geschaftsanwendung wird das Ziel gesetzt, eine geeignete Systemarchitektur zu erarbeiten, Sensoren und ihre Daten zu untersuchen, Schnittstellen bereitzuhalten und einen geeigneten Einsatz mobiler Sensorik zu finden.

Abstract: The Internet of Things (IoT) has various technologies that improve the functionalities of IoT devices to make them capable to connect and communicate with each other. The IoT with various advanced technologies and devices performing a rapid transformation of current society towards easier and smarter. As the use of IoT increases, the new challenges, requirements, and research/ innovation need have arisen to fulfill the demands. Wireless devices with low power and high data security are the most viable demand for diverse IoT applications. In an IoT environment, various nodes/ sensors are used to collect the data and different wireless communication technologies like Infrared, Bluetooth, Li-Fi, WI-Fi, Zigbee, etc. are used to transceive the data. As per the survey, among all other available wireless technologies, Bluetooth Low Energy (BLE) beacons have proved as most promising short-range wireless communication technology due to the fact of appearing everywhere or of being very common of Bluetooth-compatible technology. However, for better performance and efficiency of BLE beacons in the IoT ecosystem, regular research has needed to ensure seamless integration. For such research here we have combined the literature of IoT with Beacons. This paper consolidates: an introduction of IoT with its current market demand, challenges and five essential requirements observed. We have also discussed the research planning and strategy to discover the solutions. It also consolidates an introduction of BLE Beacon with its market demand, a survey of existing/ proposed solutions are reviewed to identify the current problem statements for research opportunities in the future.

TL;DR: A special procedure for mobile tagging is presented, which uses a distinct logo or image in order to refer to certain information instead of a QR-Code, and introduces a new similarity measure on basis of SURF feature points and a contour comparison.
Abstract: Mobile tagging became more and more popular in commercials, magazines, newspapers, and other applications during the last years. In context of commercials, a bar code containing the advertisers internet address is often used to refer a customer to related online content. Due to their robustness as well as their comparably high fault-tolerance in case of low quality pictures, QR-Code systems are commonly used for that task. Connected to that topic we present a special procedure for mobile tagging, which uses a distinct logo or image in order to refer to certain information instead of a QR-Code. Our procedure was optimized to work with a conventional smartphone – the only prerequisite for usage is the possession of a smartphone capable of capturing and analyzing the different logos with our smartphone application. To match the logos with related information and to determine their uniqueness we introduce a new similarity measure on basis of SURF feature points and a contour comparison.

TL;DR: In this article, the authors describe the design and implementation of an advanced mobile application, which enables location-based mobile augmented reality on two different mobile operating systems (i.e., iOS and Android).
Abstract: The technical capabilities of modern smart mobile devices more and more enable us to run desktop-like applications with demanding resource requirements in mobile environments. Along this trend, numerous concepts, techniques, and prototypes have been introduced, focusing on basic implementation issues of mobile applications. However, only little work exists that deals with the design and implementation (i.e., the engineering) of advanced smart mobile applications and reports on the lessons learned in this context. In this paper, we give profound insights into the design and implementation of such an advanced mobile application, which enables location-based mobile augmented reality on two different mobile operating systems (i.e., iOS and Android). In particular, this kind of mobile application is characterized by high resource demands since various sensors must be queried at run time and numerous virtual objects may have to be drawn in realtime on the screen of the smart mobile device (i.e., a high frame count per second be caused). We focus on the efficient implementation of a robust mobile augmented reality engine, which provides location-based functionality, as well as the implementation of mobile business applications based on this engine. In the latter context, we also discuss the lessons learned when implementing mobile business applications with our mobile augmented reality engine.
