This is true not only for new users of goods or services, but also for their producers. They extend the insight into the acceptance of new goods and services, e.g. at the point of sale, from a mere sales and usage quantity oriented point of view to a cause and effect oriented one. Since online reviews by consumers of many goods and services are nowadays widespread and easily available on the internet, the question arises whether their analysis can replace the more traditional approaches to measure technology acceptance, e.g., using questionnaires with TAM (Technology Acceptance Model) items. This paper tries to answer this question using IKEA's mobile catalogue app as an example. For comparisons reasons, data on the acceptance of the current version of this catalogue is collected in four different ways, (1) as answers to batteries of TAM items, (2) as assignments to pre-defined adjective pairs, (3) as textual likes and dislikes of users (simulating online reviews), and (4) as publicly available (real) reviews by users. The source for (1)-(3) is a survey with a sample of respondents, the source for (4) an online forum. The data is analyzed using partial least squares (PLS) for TAM modelling and text mining for pre-processing the textual data. The results are promising: it seems that data collection via surveys can be replaced - with some reservations - by the analysis of publicly available (real) online reviews.}, language = {en} } @incollection{BaierReseSchreiber, author = {Baier, Daniel and Rese, Alexandra and Schreiber, Stefanie}, title = {Analyzing Online Reviews to Measure Technology Acceptance at the Point of Scale: The Case of IKEA}, series = {Successful Technological Integration for Competitive Advantage in Retail Settings}, booktitle = {Successful Technological Integration for Competitive Advantage in Retail Settings}, editor = {Pantano, Eleonora}, publisher = {IGI Global}, address = {Hershey, PA}, isbn = {978-1-4666-8297-9}, doi = {10.4018/978-1-4666-8297-9.ch008}, pages = {168 -- 189}, language = {en} } @inproceedings{BaierPełkaRybickaetal., author = {Baier, Daniel and Pełka, Marcin and Rybicka, Aneta and Schreiber, Stefanie}, title = {TCA/HB Compared to CBC/HB for Predicting Choices Among Multi-Attributed Products}, series = {Selected Papers of the 3rd German-Polish Symposium on Data Analysis and Applications}, booktitle = {Selected Papers of the 3rd German-Polish Symposium on Data Analysis and Applications}, editor = {Geyer-Schulz, Andreas and Pociecha, J{\´o}zef}, publisher = {KIT Scientific Publishing}, address = {Karlsruhe}, isbn = {978-3-7315-0581-5}, doi = {10.5445/KSP/1000058747}, url = {http://nbn-resolving.de/urn:nbn:de:0072-587471}, pages = {77 -- 87}, language = {en} } @inproceedings{SchreiberBaier, author = {Schreiber, Stefanie and Baier, Daniel}, title = {Multivariate Landing Page Optimization Using Hierarchical Bayes Choice-Based Conjoint}, series = {Data Science, Learning by Latent Structures, and Knowledge Discovery}, booktitle = {Data Science, Learning by Latent Structures, and Knowledge Discovery}, editor = {Lausen, Berthold and Krolak-Schwerdt, Sabine and B{\"o}hmer, Matthias}, publisher = {Springer}, address = {Berlin [u.a.]}, isbn = {978-3-662-44982-0}, doi = {10.1007/978-3-662-44983-7_41}, pages = {465 -- 474}, language = {en} } @misc{ReseBaierGeyerSchulzetal., author = {Rese, Alexandra and Baier, Daniel and Geyer-Schulz, Andreas and Schreiber, Stefanie}, title = {How augmented reality apps are accepted by consumers: a comparative analysis using scales and opinions}, series = {Technological Forecasting and Social Change}, volume = {124}, journal = {Technological Forecasting and Social Change}, issn = {0040-1625}, doi = {10.1016/j.techfore.2016.10.010}, pages = {306 -- 319}, abstract = {Increasingly, retailers rely on interactive technologies to improve consumers' shopping experiences. On the one side, interactive kiosks and smart mirrors make use of dedicated devices and software to explain, configure, and recommend products. On the other side, computer programs - so-called apps - are installed on the consumer's own device for the same purpose. They can be used at home, or - if installed on a mobile device - in retail outlets or on the move. In all cases, augmented reality (AR) can support these purposes by placing virtual content (e.g. newfurniture) in a real environment (the consumer's home). The overall perception and acceptance toward such interactive technologies are discussed in this paper. Users' perceptions and experiences are measured by applying a modified technology acceptance model (TAM). Four experiments, two with marker-based and two with markerless AR apps are presented to support the generalization of the results, the measurement models and the measurement approach. The results are satisfactory with regard to the robustness of the TAM model. However, the relative importance of hedonic (enjoyment, pleasure, fun) and utilitarian (information) aspects varies for different kinds of AR apps and has to be considered for improvement to occur. From a measurement point of view the acquiescence bias has to be dealt with when developing scale items.}, language = {en} } @inproceedings{BaierPełkaRybickaetal., author = {Baier, Daniel and Pełka, Marcin and Rybicka, Aneta and Schreiber, Stefanie}, title = {Ratings-/Rankings-Based Versus Choice-Based Conjoint Analysis for Predicting Choices}, series = {Data Science, Learning by Latent Structures, and Knowledge Discovery}, booktitle = {Data Science, Learning by Latent Structures, and Knowledge Discovery}, editor = {Lausen, Berthold and Krolak-Schwerdt, Sabine and B{\"o}hmer, Matthias}, publisher = {Springer}, address = {Heidelberg [u.a.]}, isbn = {978-3-662-44983-7}, doi = {10.1007/978-3-662-44983-7_18}, pages = {205 -- 216}, language = {en} } @phdthesis{Schreiber, author = {Schreiber, Stefanie}, title = {Die Akzeptanz von Augmented-Reality-Anwendungen im Handel}, publisher = {Springer Gabler}, address = {Wiesbaden}, isbn = {978-3-658-29162-4}, doi = {10.1007/978-3-658-29163-1}, pages = {XXI, 328}, language = {de} }
