    Get your back straight! Learn Pilates with the Pilates Correction App
    (DELFI 2021, 2021) Meik, Anna; Schneider, Jan; Schiffner, Daniel
    Currently, a vast number of the population faces several barriers like the lack of motivation and guidance that impede them from practicing physical activities. Thus, we developed the Pilates Correction Game (PCG), a gamified application designed to support learners with the practice of Pilates. The PCG is composed of two applications: a smartphone application that tracks the learner’s back posture and a PC game that steers a rocket and calculates a score based on the smartphone's information. In this paper, we present a user experience evaluation on the PCG. Our results show that PCG was positively perceived by participants and in most cases helped them to improve their posture while doing the Pilates exercise. Furthermore, it is also motivating them to continue with the training.

    Product Roadmap Formats for an Uncertain Future: A Grey Literature Review
    (Software Management 2021, 2021) Trieflinger, Stefan; Münch, Jürgen; Bogazköy, Emre; Eißler, Patrick; Schneider, Jan; Roling, Bastian
    Product Roadmaps aim to provide direction, enable consistent development in relation to a product vision and support communication with relevant stakeholders. There are many different formats for product roadmaps, but they are often based on the assumption that the future is highly predictable. However, especially software-intensive businesses are faced with increasing market dynamics, rapidly evolving technologies and changing user expectations. Consequently, many organizations are wondering what roadmap format is appropriate for them and what components it should have to deal with an unpredictable future. Objective: This paper aims to identify suitable formats for the development and handling of product roadmaps in dynamic and uncertain markets. Method: We performed a grey literature review according to Garousi. Results: First, various components of the roadmap were identified, especially goals, themes, outcomes and outputs. Second, various product roadmap formats (e.g. theme-based roadmaps) were discovered. The roadmap components were then assigned to the various product roadmap formats. This overview aims at providing decision support for companies to select a suitable product roadmap format and adapt it to their own needs.

    Stakeholder attitudes towards digitalization in higher education institutions
    (DELFI 2019, 2019) Biedermann, Daniel; Kalbfell, Lea; Schneider, Jan; Drachsler, Hendrik
    We report the results of a group concept mapping study on the topic of digital transformation in German higher education. Students, teachers and administrative employees participated in the study where they first gathered statements which were then clustered and ranked according to importance and feasibility. The results show agreement between all groups that matters of culture and mentality remain the biggest factors for a successful digitalization of higher education. While we found agreement between groups on the importance of topics, those working at the institution are more pessimistic of cultural changes than students. The unification of service platforms and the development of validated didactical concepts for digital learning offerings are also seen as open challenges.

    Tabbi - A Tangible Interface for Educational Chatbots
    (DELFI 2020 – Die 18. Fachtagung Bildungstechnologien der Gesellschaft für Informatik e.V., 2020) Wollny, Sebastian; Schneider, Jan; Rittberger, Marc; Drachsler, Hendrik
    With the increasing popularity of Artificial Intelligence in educational research, chatbots seem to be a promising future technology that could help students with their daily problems. As part of Smart Learning Environments, they can be permanently accessible by natural language via a variety of interfaces. To investigate the property of "tangibility", we present TABBI, an interface for educational chatbots that allows students to interact with a physical robot. This robot interface will be used in future comparative studies to evaluate interaction possibilities with educational chatbots. In this paper, we describe the general idea and context of TABBI.

    “What can I help you with today?” - Exploring Opportunities of Learner Modeling for Online Educational Portals
    (DELFI 2019, 2019) Wollny, Sebastian; Schneider, Jan; Rittberger, Marc; Drachsler, Hendrik
    Online educational Portals (OEPs) subsume a field of online repositories for a wide range of stakeholders. They are characterized by easily accessible structures that do not require visitor accounts. Most OEPs therefore provide content in one way to all visitors also known as “one size fits all” approach. With this study, we examine if Web Analytics data can be used to infer the modeling of learners for OEPs. This would be the basis for additional and more personalized ways of providing content to various stakeholders. In order to draw conclusions about opportunities and limitations of Web Analytics in this regard, the data structure of the Fachportal Pädagogik, as one of the largest educational OEPs in Germany, is compared with a common Learner Modeling Framework. The evaluation of the results finally leads to two major challenges that must be overcome in order to achieve personalized content and learning experiences on OEPs.
