PublicationValue Co-Creation in Smart Services: A Functional Affordances Perspective on Smart Personal Assistants(Assoc. of Information Systems, 2020-03-09)
;Knote, RobinIn the realm of smart services, smart personal assistants (SPAs) have become a popular medium for value co-creation between service providers and users. The market success of SPAs is largely based on their innovative material properties, such as natural language user interfaces, machine-learning-powered request handling and service provision, and anthropomorphism. In different combinations, these properties offer users entirely new ways to intuitively and interactively achieve their goals and, thus, co-create value with service providers. But how does the nature of the SPA shape value co-creation processes? In this paper, we look through a functional affordances lens to theorize about the effects of different types of SPAs (i.e., with different combinations of material properties) on users' value co-creation processes. Specifically, we collected SPAs from research and practice by reviewing scientific literature and web resources, developed a taxonomy of SPAs' material properties, and performed a cluster analysis to group SPAs of a similar nature. We then derived 2 general and 11 cluster-specific propositions on how different material properties of SPAs can yield different affordances for value co-creation. With our work, we point out that smart services require researchers and practitioners to fundamentally rethink value co-creation as well as revise affordances theory to address the dynamic nature of smart technology as a service counterpart.Type: journal articleJournal: Journal of the Association for Information SystemsVolume: 22Issue: 2DOI: 0.17705/1jais.00667 -

PublicationClassifying Smart Personal Assistants: An Empirical Cluster Analysis( 2019)
;Knote, RobinThe digital age has yielded systems that increasingly reduce the complexity of our everyday lives. As such, smart personal assistants such as Amazon’s Alexa or Apple’s Siri combine the comfort of intuitive natural language interaction with the utility of personalized and situation-dependent information and service provision. However, research on SPAs is becoming increasingly complex and opaque. To reduce complexity, this paper introduces a classification system for SPAs. Based on a systematic literature review, a cluster analysis reveals five SPA archetypes: Adaptive Voice (Vision) Assistants, Chatbot Assistants, Embodied Virtual Assistants, Passive Pervasive Assistants, and Natural Conversation Assistants.Type: conference paperJournal: Hawaii International Conference on System Sciences (HICSS) -

PublicationTowards a Pattern Language for Smart Personal Assistants( 2018)
;Knote, RobinSupporting users in their daily activities, thus, making their lives more comfortable, has long been a goal for consumer-oriented systems development. With the rise of smart personal assistants (SPAs), however, we have reached a new milestone along the path towards this goal. These systems assist their owners by providing personalized and context-dependent information and service. Today's implementations reach from conversational agents, such as Siri, Cortana or Google Assistant, over chatbots, which are primarily text-based, to cognitive assistants, which assist according to a user's current cognitive or emotional state. However, although both research and practice proceed with full pace, recurring design elements of SPAs have not yet been investigated. We hence propose a pattern language for smart personal assistants to guide further empirical and design efforts. Therefore, we review existing information systems, computer science and human-computer interaction literature to find recurring design characteristics among 115 different assistants. The resulting pattern language contains 22 patterns that specify the interaction behavior and the intelligence of smart personal assistants.Type: conference paperJournal: Conference on Pattern Languages of Programs (PLoP) -
PublicationTowards Design Excellence for Context-Aware Services - The Case of Mobile Navigation Apps( 2017-02-12)
;Knote, RobinTo satisfy service customers and create unique value in a digitized world, companies must strive for exceeding customers’ expectations of e-service experience by establishing high e-service quality. However, an increasing amount of e-services is performed by context-aware mobile technology, which is able to sense and react to changes in the user’s environment. Although these context-aware services are able to address our personal needs and already determine our everyday live, knowledge on how to develop such services is sparse. In our study, we qualitatively compare three mobile navigation apps based on their user reviews in order to elicit first requirements and design approaches for e-service quality oriented design. Results show that well known e-service quality models are not fully applicable to the case of mobile navigation services.Type: conference paper -
PublicationTowards Requirement Patterns for Smart Physical Work Assistants( 2017)
;Knote, RobinAlthough physical work is becoming increasingly automated, many tasks in manufacturing, assembly or quality assurance still require human expertise, skills and subjective evaluation. Therefore, digitization offers the possibility to support such physical tasks by smart assistant systems. Being part of a larger research project, the aim of this short paper is to present requirement patterns that have evolved during a case study at a German car component manufacturer. Guided by work design theory, our research reveals four requirement patterns that support requirements specification of smart physical work assistants with regard to autonomy, task variety, task identity and feedback from tasks.Type: conference paper -
PublicationFrom Requirement to Design Patterns for Ubiquitous Computing Applications(ACM, 2016-06-06)
;Knote, Robin ;Baraki, Harun ;Geihs, KurtUbiquitous Computing describes a concept where computing appears around us at any time and any location. Respective systems rely on context-sensitivity and adaptability. This means that they constantly collect data of the user and his context to adapt its functionalities to certain situations. Hence, the development of Ubiquitous Computing systems is not only a technical issue and must be considered from a privacy, legal and usability perspective, too. This indicates a need for several experts from different disciplines to participate in the development process, mentioning requirements and evaluating design alternatives. In order to capture the knowledge of these interdisciplinary teams to make it reusable for similar problems, a pattern logic can be applied. In the early phase of a development project, requirement patterns are used to describe recurring requirements for similar problems, whereas in a more advanced development phase, design patterns are deployed to find a suitable design for recurring requirements. However, existing literature does not give sufficient insights on how both concepts are related and how the process of deriving design patterns from requirements (patterns) appears in practice. In our work, we give insights on how trust-related requirements for Ubiquitous Computing applications evolve to interdisciplinary design patterns. We elaborate on a six-step process using an example requirement pattern. With this contribution, we shed light on the relation of interdisciplinary requirement and design patterns and provide experienced practitioners and scholars regarding UC application development a way for systematic and effective pattern utilization.Type: conference paperScopus© Citations 9 -
