Among the variety of technological innovations and considering the scarcity of resources, it is unclear which technologies to focus on and where to implement them in the value chain. To develop the most probable technology forecast that addresses the application of emerging technologies in the grocery value chain within the current decade, we conduct a two-stage Delphi study. Our results suggest a high relevance of almost all technologies. The panel is only skeptical about three specific projections. As a consequence, grocers are advised to build up knowledge regarding the application of these technologies in the most promising areas of their value chain.

When measured at short intervals, children’s growth shows characteristic patterns that can be of great importance for clinical purposes. Objective: To study whether measuring height on a daily basis using an APP is practicable and user-friendly. Methods: Recruitment took place via Snowball Sampling. Thirteen out of 14 contacted families signed up for a study period of 12 weeks with altogether 22 healthy children aged 3 to 13 years (response rate 93%). The study started with a visit to the family home for the setup of the measurement site, conventional height measuring and initial training of the new measurement process. Follow-up appointments were made at four, eight and 12 weeks. The children’s height was measured at daily intervals at their family homes over a period of three months. Results: The parents altogether recorded 1704 height measurements and meticulously documented practicability and problems when using the device. A 93% response rate in recruitment was achieved by maintaining a high motivation within the families. Contact with the principal investigator was permanently available, including open communication, personal training and attendance during the appointments at the family homes. Conclusion: Measuring height by photographic display is interesting for children and parents and can be used for height measurements at home. A positive response rate of 13 out of 14 families with altogether 22 children highlights feasible recruitment and the high convenience and user-friendliness of daily APP-supported height measurements. Daily APP measurements appear to be a promising new tool for longitudinal growth studies.

To this end, an approach to age-appropriate training will be designed with the help of AR technology. In times of the corona pandemic, a special research design is necessary for the initial survey of the current state in the companies, which will be systematically elaborated in this paper. The results of the previous methodological considerations illustrate the necessity of a mix of methods to generate a deeper insight into the work processes. Video-based retrospective interviews seem to be a suitable instrument to adequately capture the employees' interpretative perspectives on their work activities. In conclusion, the paper identifies specific challenges, such as creating acceptance among employees, open questions, e.g., how a transfer or generalization of the results can succeed, and hypotheses that will have to be tested in the further course of the research process.

Jeder Mensch steht vor Beginn einer Fortbewegung vor den Fragen „Wo bin ich?“, „Wo liegt mein Ziel?“ und „Wie komme ich dahin?“. Ein Großteil der auf dem Markt befindlichen Navigationssysteme für Fußgänger stellen reduzierte Varianten aus Fahrzeugen dar und basieren auf 2D- Kartendarstellungen oder bilden die Realität als dreidimensionales Modell ab. Navigationsprobleme entstehen dann, wenn es dem Nutzer nicht gelingt, die Information aus der Anweisung auf die Wirklichkeit zu beziehen und umzusetzen. Ein möglicher Grund dafür liegt in der Visualisierung der Navigationsanweisung. Die räumliche Wahrnehmung des Menschen erfolgt ausgehend von einem bestimmten Betrachtungsstandpunkt und bringt die Lage von Objekten und deren Beziehung zueinander zum Ausdruck. Der Einsatz von Augmented Reality (erweiterte Realität) entspricht dem Erscheinungsbild der menschlichen Wahrnehmung und ist für Menschen eine natürliche und zugleich vertraute Ansichtsform. Im Unterschied zu kartographischer Visualisierung wird die Umwelt mittels Augmented Reality nicht modelliert, sondern realitätsgetreu abgebildet und ergänzt. Das Ziel dieser Arbeit ist ein Navigationsverfahren, das der natürlichen Fort-bewegung und Sichtweise von Fußgängern gerecht wird. Das Konzept basiert auf dem Einsatz einer Kombination aus Realität und virtueller Realität zu einer erweiterten Ansicht. Da keine Darstellungsform als die Route selbst besser geeignet ist, um einen Routenverlauf zu beschreiben, wird die Realität durch eine virtuelle Route erweitert. Die perspektivische Anpassung der Routendarstellung erfordert die sensorische Erfassung der Position und Lage des Betrachtungsstandpunktes. Das der Navigation zu Grunde liegende Datenmodell bleibt dem Betrachter dabei verborgen und ist nur in Form der erweiterten Realität sichtbar. Der im Rahmen dieser Arbeit entwickelte Prototyp trägt die Bezeichnung RealityView. Die Basis bildet ein freies und quelloffenes Navigationssystem, das für die Fußgängernavigation modular erweitert wurde. Das Ergebnis ist ein smartphonebasierter Navigationsprototyp, in dem die Ansichtsform einer zweidimensionalen Bildschirmkarte im Grundriss und die Darstellung einer erweiterten Realität im Aufriss kombiniert werden. Die Evaluation des Prototyps bestätigt die Hypothese, dass der Einsatz von Augmented Reality für die Navigation von Fußgängern möglich ist und von der Nutzergruppe akzeptiert wird. Darüber hinaus bescheinigen Wissenschaftler im Rahmen von Experten-interviews den konzeptionellen Ansatz und die prototypische Umsetzung des RealityView. Die Auswertung einer Eye-Tracking-Pilotstudie erbrachte den Nachweis, dass Fußgänger die Navigationsanweisung auf markante Objekte der Umwelt beziehen, deren Auswahl durch den Einsatz von Augmented Reality begünstigt wird. N2 - Pedestrian traffic takes place in public spaces and provides a seamless connection from door to door. Right before the start of a movement, every human being faces the following questions "Where am I?", "What is my goal?" and "How do I get there?". Existing navigation systems for pedestrians are based on 2D map representations or depict reality as a three-dimensional model. As a result, the majority of the systems on the market for pedestrians are smaller versions of vehicle navigation systems. Navigation problems can occur if the user is unable to relate the information of an instruction to reality and cannot implement it. One possible reason for this is the visualization of the navigation instruction. Peoples spatial perception takes place from their own perspective and shows how objects are positioned and how they are related to each other. The use of Augmented Reality corresponds to the appearance of human perception, and this is a natural and yet familiar view. Compared to cartographic visualization techniques reality is not modeled but mapped realistically and refers to the environment. The concept of this thesis is directly linked to the current state of research and examines the use of a simple method and target group-oriented representation, which meets the natural movement of pedestrians. Its central focus is the combination of reality and virtual reality to a common view. This view will be extended by a virtual route representation, which follows the route course in reality. No other form of representation is better suited to explain the course of a route than the route itself. The perspective adjustment and the calculation of the virtual image scene require a data model, which remains hidden from the viewer and only appears in form of a virtual route. The navigation prototype, which is developed in this study, is based on Augmented Reality and is called RealityView. Its base is a free and open source navigation platform, which was expanded modularly into a pedestrian navigation system. The result is a smartphone-based navigation prototype, which combines the two forms of a two-dimensional screen map in plan with the illustration of an Augmented Reality in elevation. The validation of the prototype confirms the hypothesis that the use of Augmented Reality for pedestrian navigation is possible and is also accepted by the user group. In addition, in interviews with experts scientists have confirmed the conceptual approach and the implementation of the RealityView-prototype. The evaluation of an eye-tracking pilot study proved that the use of Augmented Reality favors the selection of prominent objects in the environment.

The ability to speed up the transfer of knowledge between any kind of knowledge carriers in business processes with AR techniques can lead to a huge competitive advantage, for instance in manufacturing. This includes the transfer of person-bound knowledge as well as externalized knowledge of physical and virtual objects. The contribution builds on a time-dependent knowledge transfer model and conceptualizes an adaptable, AR-based application. Having the intention to accelerate the speed of knowledge transfers between a manufacturer and an information system, empirical results of an experimentation show the validity of this approach. For the first time, it will be possible to discover how to improve the transfer among knowledge carriers of an organization with knowledge-driven information systems (KDIS). Within an experiment setting, the paper shows how to improve the quantitative effects regarding the quality and amount of time needed for an example manufacturing process realization by an adaptable KDIS.
