Design Principles of Mobile Information Systems in the Digital Transformation of the Workplace - Utilization of Smartwatch-based Information Systems in the Corporate Context

During the last decades, smartwatches emerged as an innovative and promising technology and hit the consumer market due to the accessibility of affordable devices and predominant acceptance caused by the considerable similarity to common wristwatches. With the unique characteristics of permanent availability, unobtrusiveness, and hands-free operation, they can provide additional value in the corporate context. Thus, this thesis analyzes use cases for smartwatches in companies, elaborates on the design of smartwatch-based information systems, and covers the usability of smartwatch applications during the development of smartwatch-based information systems. It is composed of three research complexes. The first research complex focuses on the digital assistance of (mobile) employees who have to execute manual work and have been excluded so far from the benefits of the digitalization since they cannot operate hand-held devices. The objective is to design smartwatch-based information systems to support workflows in the corporate context, facilitate the daily work of numerous employees, and make processes more efficient for companies. During a design science research approach, smartwatch-based software artifacts are designed and evaluated in use cases of production, support, security service, as well as logistics, and a nascent design theory is proposed to complement theory according to mobile information system research. The evaluation shows that, on the one hand, smartwatches have enormous potential to assist employees with a fast and ubiquitous exchange of information, instant notifications, collaboration, and workflow guidance while they can be operated incidentally during manual work. On the other hand, the design of smartwatch-based information systems is a crucial factor for successful long-term deployment in companies, and especially limitations according to the small form-factor, general conditions, acceptance of the employees, and legal regulations have to be addressed appropriately. The second research complex addresses smartwatch-based information systems at the office workplace. This broadens and complements the view on the utilization of smartwatches in the corporate context in addition to the mobile context described in the first research complex. Though smartwatches are devices constructed for mobile use, the utilization in low mobile or stationary scenarios also has benefits due they exhibit the characteristic of a wearable computer and are directly connected to the employee’s body. Various sensors can perceive employee-, environment- and therefore context-related information and demand the employees’ attention with proactive notifications that are accompanied by a vibration. Thus, a smartwatch-based and gamified information system for health promotion at the office workplace is designed and evaluated. Research complex three provides a closer look at the topic of usability concerning applications running on smartwatches since it is a crucial factor during the development cycle. As a supporting element for the studies within the first and second research complex, a framework for the usability analysis of smartwatch applications is developed. For research, this thesis contributes a systemization of the state-of-the-art of smartwatch utilization in the corporate context, enabling and inhibiting influence factors of the smartwatch adoption in companies, and design principles as well as a nascent design theory for smartwatch-based information systems to support mobile employees executing manual work. For practice, this thesis contributes possible use cases for smartwatches in companies, assistance in decision-making for the introduction of smartwatch-based information systems in the corporate context with the Smartwatch Applicability Framework, situated implementations of a smartwatch-based information system for typical use cases, design recommendations for smartwatch-based information systems, an implementation of a smartwatch-based information system for the support of mobile employees executing manual work, and a usability-framework for smartwatches to automatically access usability of existing applications providing suggestions for usability improvement

The Emerging Internet of Things Marketplace From an Industrial Perspective: A Survey

The Internet of Things (IoT) is a dynamic global information network consisting of internet-connected objects, such as Radio-frequency identification (RFIDs), sensors, actuators, as well as other instruments and smart appliances that are becoming an integral component of the future internet. Over the last decade, we have seen a large number of the IoT solutions developed by start-ups, small and medium enterprises, large corporations, academic research institutes (such as universities), and private and public research organisations making their way into the market. In this paper, we survey over one hundred IoT smart solutions in the marketplace and examine them closely in order to identify the technologies used, functionalities, and applications. More importantly, we identify the trends, opportunities and open challenges in the industry-based the IoT solutions. Based on the application domain, we classify and discuss these solutions under five different categories: smart wearable, smart home, smart, city, smart environment, and smart enterprise. This survey is intended to serve as a guideline and conceptual framework for future research in the IoT and to motivate and inspire further developments. It also provides a systematic exploration of existing research and suggests a number of potentially significant research directions.Comment: IEEE Transactions on Emerging Topics in Computing 201

Enabling the Adoption of Wearable Computers in Enterprises - Results of Analyzing Influencing Factors and Challenges in the Industrial Sector

Wearable computers like smart glasses or smartwatches enable the use of information systems in application scenarios in which information technology has rarely been used until now. The reason for this is, that users are able to interact with the devices hands-free, e.g. by using voice commands. A hands-free use is in particular relevant for enterprises in the industrial sector, as industrial workers often need to perform tasks manually, e.g. in manufacturing or maintenance. However, the technology is currently not used widely in enterprises. Thus, the aim of our research is to identify influencing factors and related challenges of using wearable computers in order to analyze how its adoption can be increased. Based on an empirical interview study within the industrial sector, we identified 11 influencing factors and 25 related challenges which affect the adoption of wearable computers

The Internet of Things (IoT) concept is evolving rapidly and influencing newdevelopments in various application domains, such as the Internet of MobileThings (IoMT), Autonomous Internet of Things (A-IoT), Autonomous Systemof Things (ASoT), Internet of Autonomous Things (IoAT), Internetof Things Clouds (IoT-C) and the Internet of Robotic Things (IoRT) etc.that are progressing/advancing by using IoT technology. The IoT influencerepresents new development and deployment challenges in different areassuch as seamless platform integration, context based cognitive network integration,new mobile sensor/actuator network paradigms, things identification(addressing, naming in IoT) and dynamic things discoverability and manyothers. The IoRT represents new convergence challenges and their need to be addressed, in one side the programmability and the communication ofmultiple heterogeneous mobile/autonomous/robotic things for cooperating,their coordination, configuration, exchange of information, security, safetyand protection. Developments in IoT heterogeneous parallel processing/communication and dynamic systems based on parallelism and concurrencyrequire new ideas for integrating the intelligent “devices”, collaborativerobots (COBOTS), into IoT applications. Dynamic maintainability, selfhealing,self-repair of resources, changing resource state, (re-) configurationand context based IoT systems for service implementation and integrationwith IoT network service composition are of paramount importance whennew “cognitive devices” are becoming active participants in IoT applications.This chapter aims to be an overview of the IoRT concept, technologies,architectures and applications and to provide a comprehensive coverage offuture challenges, developments and applications

Tandem: A Context-Aware Method for Spontaneous Clustering of Dynamic Wireless Sensor Nodes

Wireless sensor nodes attached to everyday objects and worn by people are able to collaborate and actively assist users in their activities. We propose a method through which wireless sensor nodes organize spontaneously into clusters based on a common context. Provided that the confidence of sharing a common context varies in time, the algorithm takes into account a window-based history of believes. We approximate the behaviour of the algorithm using a Markov chain model and we analyse theoretically the cluster stability. We compare the theoretical approximation with simulations, by making use of experimental results reported from field tests. We show the tradeoff between the time history necessary to achieve a certain stability and the responsiveness of the clustering algorithm
