Conversational agents (CAs) are rapidly changing the way humans and computers interact. Through developments in natural language processing, CAs are increasingly capable of conducting human-like conversations with users. Furthermore, human-like features (e.g., having a name or an avatar) lead to positive user reactions as if they were interacting with a real human conversational partner. CAs promise to replace or supplement traditional interactions between humans (e.g., counseling, interviews). One field of CA-human interaction that is not yet fully understood in developing human-like CAs is donating to a good cause. Notably, many charities rely on approaching people on the streets to raise funds. Against this background, the questions arise: How should a CA for raising funds for non-profit organizations be designed and how does human-like design of a CA influence the user’s donation behavior. To explore these two questions, we conducted a 2 × 2 experiment with 134 participants.

Driven by technological advances, smart personal assistants (SPA) have gained importance in human–computer interaction. SPA can influence user behavior and persuade users to reach a specific outcome. However, users often lack the motivation to interact with SPA. One way to support this interaction is persuasive system design – considering concepts as gamification and nudging. Although SPA research has increased recently, there is still no shared knowledge about persuasive designs. Therefore, we aim to identify the current state-of-the-art Design for persuasive SPA to understand how interactions and designs can be improved. Thus, we conduct a systematic literature analysis to represent how gamification and digital nudging are used to design SPA and conclude if and how those concepts can support SPA interactions. Consequently, we contribute to theory, providing better understanding about SPA interaction and design to make SPA more engaging and entertaining. Practitioners can use this contribution for persuasive SPA designs.

Recent socio-technical developments caused by ongoing digitalization (e.g., robotic process automation, artificial intelligence, anthropomorphic systems) or the COVID-19 pandemic (e.g., an increasing number of remote working employees and hence, increasing number of virtual collaboration) change the work environment and culture. Digital and smart workplace technol-ogies facilitate business processes and provide tools for efficient communication and (virtual) collaboration, “increasing the productivity of the workforce in the information age” (Attaran et al. 2019, p. 1). Especially in times of the COVID-19 pandemic, digital technologies play a crucial role in keeping us socially close, connected, and collaborative while increasing the phys-ical distance between humans. However, this development affects the health of employees (Tarafdar et al. 2013). In research, for example, it has long been known that the increased usage of digital technologies and media (DTM) may cause stress, leading to potentially harmful reac-tions in individuals. Research has noted this specific form of stress as technostress (Ayyagari et al. 2011; Tarafdar et al. 2007; Tarafdar et al. 2011; Tarafdar et al. 2019), which is an umbrella term for causes, negative organizational outcomes, and negative humanistic outcomes resulting from the use of DTM at work. The simultaneous consideration of humanistic (e.g., well-being, equality) and organizational outcomes (e.g., efficiency, productivity) is an integral part of a socio-technical system (Beath et al. 2013; Mumford 2006), which is at the core of the IS discipline (Bostrom et al. 2009; Chiasson and Davidson 2005). However, a review from Sarker et al. (2019) regarding published research articles in one of the top journals within the IS community revealed that most reviewed studies (91%) had focused exclusively on instrumental goals. They conclude that “many IS researchers have forgotten or ignored the premise that technologies need to benefit humankind overall (Majchrzak et al. 2016), not just their economic condition” (Sarker et al. 2019, p. 705). Especially as humanistic outcomes can lead to even more positive instrumental outcomes. Hence, Sarker et al. (2019) call for focusing on the connection between humanistic and instru-mental outcomes, enabling a positive synergy resulting from this interplay. For this reason, this dissertation adopts a socio-technical perspective. It aims to conduct re-search that links instrumental outcomes with humanistic objectives to ultimately achieve a healthier use of DTMs at the digital workplace. It is important to note that the socio-technical perspective considers both the technical component and the social component privileging nei-ther one of them and sees outcomes resulting from the reciprocal interaction between those two.Therefore, the dissertation focuses on the interaction while applying pluralistic methodological approaches from qualitative (e.g., semi-structured interviews, focus group discussions) and quantitative research (e.g., collection from a field study or survey research). It provides a theo-retical contribution applying both behavioral research (i.e., analysis of cause-and-effect rela-tionships) and design-oriented research (i.e., instructions for designing socio-technical information systems). Overall, this work addresses four different areas within the reciprocal interaction between the social and technical components: the role of the technical component, the role of the social component, DTMs fostering a fit between the technical and social compo-nents, and the imminent misfit between these two due to ongoing digitalization. First, to contribute to an understanding of the technical component’s role, this thesis presents new knowledge on the characteristics and features of DTM and their influence on employee health and productivity. Research on the design of digital workplaces examined different design approaches, in which information exchange and sharing documents or project support were regarded (Williams and Schubert 2018). However, the characteristics of DTM also play an es-sential role in the emergence of technostress (Dardas and Ahmad 2015). This thesis presents ten characteristics of DTM that affect technostress at an individual’s workplace, including a measurement scale and analysis on how these characteristics affect technostress. Besides, also, the provision of functional features by DTMs can affect instrumental outcomes or humanistic objectives. For example, affording users with certain kinds of autonomy regarding the config-uration of DTM while they work towards their goals could have a tremendous effect on pursu-ing goals and well-being (Patall et al. 2008; Ryan and Deci 2000). Therefore, this thesis presents knowledge regarding the design of DTM on the benefits of affording users with autonomy. Furthermore, it shows that merely affording more autonomy can have positive effects above and beyond the positive effects of the actualization of affordance. Second, to contribute to an understanding of the social component’s role, this thesis presents new knowledge on contextual and individual factors of social circumstances and their influence on employee health and productivity. In this context, the influence of the COVID-19 pandemic on the intensity of technostress among employees is considered, as work became more digital almost overnight. Therefore, this thesis provides empirical insights into digital work and its context in times of the COVID-19 pandemic and its effect on employees’ well-being, health, and productivity. Furthermore, measures to steer the identified effects if the situation in the course of the COVID-19 pandemic persists or comparable disruptive situations should re-occur are discussed. On the other hand, this research takes a closer look at the effect of an individual preference regarding coping styles in dealing with upcoming technostress. A distinction is made between the effects of two different coping styles, namely active-functional and dysfunctional, on strain as a humanistic outcome and productivity as an instrumental outcome. In the course of this, evidence is provided that coping moderates the relationship between the misfit within the socio-technical system and strain as proposed by the psychological theory of job demands-resources model (Demerouti et al. 2001). Third, to contribute to a successful fit between the technical and social components, this thesis presents frameworks and guidelines on the design of DTM, which understand the social com-ponent (here the user and her/his environment) and adjust accordingly to the needs of their users. Therefore, the thesis provides knowledge on the design of DTMs that support users in applying stress management techniques and build the foundation for stress-sensitive systems (i.e., systems that aim to mitigate stress by applying intervention measures on the social and technical component (Adam et al. 2017)). As a matter of fact, a framework for collecting and storing data (e.g., on the user and her/his environment) is developed and experiences with im-plementing a prototype for life-integrated stress assessment are reported. The experiences from this and the existing knowledge in the literature will finally be aggregated to a mid-range design theory for mobile stress assessment. To contribute to the fourth and last aspect, the imminent misfit within the socio-technical sys-tem due to ongoing digitalization, this thesis presents new knowledge regarding digital work demands that potentially affect both employees’ health and instrumental outcomes. The current version of technostress’s theoretical foundation was introduced more than ten years ago by Tarafdar et al. (2007). However, the interaction with and use of DTM has considerably changed along with the societal and individual expectations. Therefore, this thesis puts the current con-cept of technostress to test. As a result, a new theory of digital stress, as an extension of the concept of technostress, is proposed with twelve dimensions – instead of five dimensions within the concept of Tarafdar et al. (2007) – that could be hierarchically structured in four higher-order factors. This theory holistically addresses the current challenges that employees have to deal with digitalization. To sum up, this dissertation contributes to the IS community’s knowledge base by providing knowledge regarding the interaction between employees and their digital workplace to foster the achievement of humanistic and instrumental outcomes. It provides both behavioral research and design-oriented research while using pluralistic methodological approaches. For this pur-pose, this thesis presents knowledge about the different components within the socio-technical system, design knowledge on DTMs fostering the fit between these components, and an under-standing of an upcoming misfit due to the ongoing digitalization. Overall, this research aims to support the successful change towards a healthy digital workplace in the face of digitalization.

This finding supports assumptions made by other researches (e.g. Morana et al. 2017) and shows the importance that these systems may have in improving organisational performance (through its employees) which may also lead to a higher satisfaction of the latter. Furthermore, it demonstrates, that VAs are not only beneficial for organisations when applied in contact with its customers (cf. ...

When attempting to solve a problem, humans call upon cognitive resources. These resources are limited, and the degree of their utilisation is described as cognitive load. While the number of parameters to be taken into account and to be processed by modern-day knowledge workers increases, their cognitive resources do not. Research shows that too high a load can increase stress and failure rates and decrease the work satisfaction and performance of employees. It is thus in the interest of organisations to reduce the cognitive load of their employees and keep it at a moderate level. One way to achieve this may be the application of virtual assistants (VAs), software programs, that can be addressed via voice or text commands and respond to the users’ input. This study uses a laboratory experiment with N = 91 participants comparing two groups in their ability to solve a task. One group was able to make use of a VA while the other could not. Besides task performance, the cognitive load of the participants was measured. Results show that (a) cognitive load is negatively related to task performance, (b) the group using the VA performed better at the task and (c) the group using the VA had a lower cognitive load. These findings show that VAs are a viable way to support employees and can increase their performance. It adds to the growing field of IS research on VAs by expanding the field for the concept of cognitive load.
... One phenomenon in this wave are conversational agents (CAs), defined as software which users interact with through natural language (McTear et al. 2016). Equipped with increasing capabilities to assist users in a variety of tasks (Maedche et al. 2016;Morana et al. 2017), these agents permeate our private and professional lives in different forms, including digital assistants on smartphones (Chattaraman et al. 2018), chatbots on social media (Xu et al. 2017) or as physically embodied service robots (Stock 2018;Stock and Merkle 2018). ...

The increasing capabilities of conversational agents (CAs) offer manifold opportunities to assist users in a variety of tasks. In an organizational context, particularly their potential to simulate a human-like interaction via natural language currently attracts attention both at the customer interface as well as for internal purposes, often in the form of chatbots. Emerging experimental studies on CAs study the impact of anthropomorphic design elements, so-called social cues, on user perception. However, while these studies provide valuable prescriptive knowledge on selected social cues, they neglect the potential detrimental influence of the limited responsiveness of present-day conversational agents. In practice, many CAs fail to continuously provide meaningful responses in a conversation due to the open nature of natural language interaction, which negatively influences user perception and often led to CAs being discontinued in the past. Thus, designing a CA that provides a human-like interaction experience while minimizing the risks associated with limited conversational capabilities represents a substantial design problem. This study addresses the aforementioned problem by proposing and evaluating a design for a CA that offers a human-like interaction experience while mitigating negative effects due to limited responsiveness. Through the presentation of the artifact and the synthesis of prescriptive knowledge in the form of a nascent design theory for anthropomorphic enterprise CAs, this research adds to the growing knowledge base on designing human-like assistants and supports practitioners seeking to introduce them in their organizations.
... Aufgrund der jüngsten technologischen Fortschritte und der Popularität von Textnachrichten als Kommunikationsform ist bei Unternehmen insbesondere das Interesse an Chatbots gestiegen. In vielen Branchen werden Chatbots bereits produktiv eingesetzt, um Nutzer bei der Suche nach relevanten Informationen über Produkte und Dienstleistungen zu unterstützen und einfache Prozesse, wie etwa bei der Flug-oder Hotelbuchung, zu automatisieren ( Morana et al. 2017). Die Schweizerische Post setzt beispielsweise einen Chatbot auf ihrer Webseite ein, um häufige Kundenanfragen zu Produkten und Dienstleistungen von PostFinance automatisiert zu beantworten Stucki et al. , 2020. ...

Chatbots sind softwarebasierte Systeme, die mittels natürlicher Sprache mit Menschen interagieren. Viele Unternehmen setzen zunehmend auf Chatbots, um Kunden bei der Suche nach Informationen über Produkte oder Dienstleistungen und bei der Durchführung einfacher Prozesse zu unterstützen. Nichtsdestotrotz ist die Akzeptanz von Chatbots bei vielen Nutzern derzeit noch gering. Ein Grund dafür ist, dass sich die Interaktion mit Chatbots nur selten natürlich und menschlich anfühlt. Es wächst deshalb die Erkenntnis, dass neben einer guten technischen Plattform auch weitere Faktoren bei der Gestaltung von Chatbots beachtet werden sollten. Die soziotechnische Gestaltung von Chatbots fokussiert sich daher auf die sozialen Signale eines Chatbots. Diese sozialen Signale (z. B. Lächeln, Sprachstil oder Antwortgeschwindigkeit) spielen nicht nur in der zwischenmenschlichen Kommunikation, sondern auch in der Interaktion mit Chatbots eine grosse Rolle. Dieser Artikel erläutert die Grundlagen der soziotechnischen Gestaltung von Chatbots, verdeutlicht die Wirkung sozialer Signale anhand eines Forschungsbeispiels und diskutiert kritisch die Vermenschlichung von Chatbots.
... According to Aldrich [10, p. 17] a SH can be defined as "[…] a residence equipped with computing and information technology which anticipates and responds to the needs of the occupants […]." By the extension "smart or intelligent", the system (the "house" in our case), is able to give tailored assistance for the users [11]. In this study we define SH according to [12] as a residence "equipped with a high-tech network, linking sensors and domestic devices, appliances and features that can be remotely monitored, accessed or controlled, and provide services that respond to the needs of its inhabitants". ...

With the rapid development of the Internet of Things, intelligent systems are increasingly finding their way into everyday life and into people’s homes. With the spread of these technologies, there is a growing concern about what sensitive data is collected and what it is used for. Unfortunately, the role of privacy has remained largely unexplored in the smart home (SH) usage context. This study addresses this gap in literature: to what extend users’ concerns for information privacy influence the intended SH usage. This study takes an interactional psychology perspective and links the dimensions of the privacy concerns to the intention to use SH devices. Therefore, a multi-theoretical model using Smart PLS 3.2.8 was tested. This study contributes to the literature on privacy, and SH usage by exploring how and why privacy concerns influence participants’ intended SH usage. The findings, derived from the empirical study emphasize the importance of addressing privacy concerns because they are capable of directly and indirectly influencing the intended SH usage. Finally, the results which indicate new directions for privacy and SH research are discussed and implications for research and practice are given.
... Smart Devices wie Tablets oder Smart Glasses erlauben neue Möglichkeiten zur Prozesserhebung. Insbesondere Smart Glasses eignen sich zu Modellierungszwecken, da sie Spracherkennung und deren Verarbeitung unterstützen [Mo17] und somit erweiterte Interaktionsmöglichkeiten bereitstellen ("Hände frei"), die für die ungestörte Durchführung der Prozessausführung [HS16] notwendig sind. Diesem Vorteil gegenüber steht die limitierte Darstellung von Elementen aufgrund der Displaygröße [Ja18], [QL15], sodass IT-Organisationen vor der Herausforderung stehen, Informationssysteme mit adäquaten User Interfaces (UI) für neuartige Technologien zur Verfügung zu stellen [UA16]. ...

Mobile und innovative Prozessmodellierungswerkzeuge, die innerhalb von Arbeitsumgebungen wie z.B. in der Produktion oder in der Wartung verwendet werden können, sind bisher nachrangig untersucht worden, obwohl sie eins-zu-eins Prozesserhebungen direkt am Arbeitsplatz durch den Domänenexperten ermöglichen. Eine direkte Prozesserhebung reduziert falsche Prozessabweichungen und den gesamten Modellierungsaufwand, da beispielsweise keine Abstimmungsaufwände zwischen Domänen- und Modellierungsexperten auftreten. Innovative mobile Endgeräte wie Smart Glasses haben sich in technischen Prozessen bereits als Assistenzsystem etabliert. Der vorliegende Beitrag entwickelt auf dieser Basis eine sprachbasierte Modellierungsumgebung, die es erlaubt ereignisgesteuerte Prozessketten unter Verwendung von Smart Glasses zu modellieren. Durch Nutzung des Tools können Arbeiter syntaktisch und semantisch korrekte EPK-Prozessmodelle bereits während der Arbeitsdurchführung erheben und Geschäftsprozesse somit parallel zu ihrer Ausführung modellieren.
