To understand people’s perceived barriers and benefits in regard to interactive digital textiles and to derive empirically founded design and communication guidelines, we conducted an empirical study based on a synthesis of the Unified Theory and Acceptance and Use of Technology 2 (UTAUT2) and the Smart Textile Technology Acceptance Model (STTAM). In a scenario-based quantitative user study with N = 324 participants, we evaluated the projected acceptance of two exemplary textile products in a between-subject design. The first product addressed wearables in form of a smart jacket and the second product referred to technology augmented living environments in form of a smart armchair. Regression analyses revealed that the combined model (UTAUT2 and STTAM) explained over 80% of the variance of the participants intention to use the smart armchair (80.3%) as well as the smart jacket (84.7%): For the smart armchair, the model dimensions performance expectancy, hedonic motivation, washability, and input modality were decisive, while performance expectancy, hedonic motivation, and connectivity were relevant for the smart jacket. We conclude with empirically based communication and design guidelines to increase the acceptance of interactive digital textiles.</div> </div> <div class="field field--name-field-signature field--type-string-long field--label-hidden field__item">Brauner P., Offermann-van Heek J., Ziefle M.

Digital textiles are reaching maturity and first technology augmented cloths are becoming commercially available. However, little is known about the acceptance and projected use of digital textiles for/in home environments and whether acceptance is shaped by age, gender, expertise in interacting with technology, or other aspects of user diversity. In a survey with n=136 participants, we identified and quantified factors that influence the adoption and rejection of a smart cushion as example for digital textiles. We found that attitude towards technology and attitude towards automation are decisive for the projected acceptance, while age plays a minor role. In addition, we provide a customer segmentation based on the projected use and provide detailed descriptions of adopters and rejecters as well as their model-based evaluations of the smart interactive cushion. The article concludes with open research questions and strategies for practitioners to leverage smart textile interfaces as basis for many innovative products in the future.</div> </div> <div class="field field--name-field-signature field--type-string-long field--label-hidden field__item">Heek, J.

Modern computer interfaces increase in functionality and potential, shrink in size, and enter our everyday lives. Apart from the technical perspective, it is important to understand if and under which conditions people adopt these technologies and which factors constitute perceived barriers of technology acceptance. In this work we examine people&#039;s attitudes towards smart textiles and their relationship to the intention to use these products in their home environment. This article provides a precise modeling of younger and older people in regard to expertise in interacting with technology, their desire to control and automate functions in their home environment, and the evaluation of a smart cushion for controlling the home environment, using the Smart Textile Technology Acceptance Model that is derived from the Unified Theory of Acceptance and Use of Technology 2 model. This model was applied for a specific smart textile product and the evaluation was focused on user-diversity, attitudes, and age. The article concludes with open research questions and guidelines for practitioners to leverage the benefits of smart textile user interfaces.</div> </div> <div class="field field--name-field-signature field--type-string-long field--label-hidden field__item">Brauner, P., Van Heek, J., Ziefle, M.: Age, Gender, and Technology Attitude as Factors for Acceptance of Smart Interactive Textiles in Home Environments.

An increasing number of everyday objects are equipped with smart technology and start to form the Internet of Things. Yet, interacting with these devices is based on conventional surfaces made of glass, metal, or plastic. We believe that textile interaction surfaces will be the next frontier of ubiquitous computing and identified many blank spots in the research landscape. Peoples’ perception and acceptance of smooth and soft interaction surfaces is insufficiently understood. In this paper we present a study in which 90 people of a wide age range evaluated the suitability of smart textiles in different usage scenarios in the home environment. Overall, a solid willingness to use smart textiles as input devices was found, even though there were conditional acceptance criteria which should be given before participants would be willing to buy them. In contrast to many other technology contexts, however, age is not decisive in the evaluation of the usefulness of smart textiles. Younger and older adults seem to have a quite similar evaluation, hinting at a quite generic acceptance pattern.</div> </div> <div class="field field--name-field-signature field--type-string-long field--label-hidden field__item">Ziefle, M., Brauner, P., van Heek, J.: Intentions to Use Smart Textiles in AAL Home Environments: Comparing Younger and Older Adults.

While this is the most prominent use of fabric, we present a standalone interface that builds on the natural set of interactions a piece of fabric affords, and that is feasible for industrial production. By integrating stitched patterns made of conductive thread into a square piece of fabric, we are able to sense established connections within this pattern and map these to a model how the cloth is folded. An integrated microcontroller tracks these connections and communicates them as two-dimensional continuous value changes to a host application. We present the technical construction of our prototype, a particular clip- on technique to establish the connection between fabric and electronics, and first insights into recognizing different grip gestures.</div> </div> <div class="field field--name-field-signature field--type-string-long field--label-hidden field__item">Heller, F., Lee, H.-Y.

The attributes were rated with different importances. Users request non-wearable textile input devices with no noticeable electronics for the living room. Gender, but no age effects were identified, as women prefer health applications, whereas men prefer media control.

As a framework of the research presented here we introduce a currently running interdisciplinary research project, in which novel textile input devices are to be developed, iteratively designed, and evaluated. In order to learn about the individual requirements for using smart textiles in a home con- text, we carried out a exploratory questionnaire study in which 72 participants (20-76 y) evaluated perceived benefits and barriers of smart textiles in the home context. Results show a first insight into user experience the general willingness to adopt smart textile input devices. Also, the perceived suitability of functions to be controlled by those novel input devices as well as the reported appropri- ateness of different rooms and device types in which smart input devices could be integrated were collected. Results show, overall, a high willingness of partic- ipants to use smart textiles as input devices.</div> </div> <div class="field field--name-field-signature field--type-string-long field--label-hidden field__item">Ziefle, M., Brauner, P., Heidrich, F., Möllering, C., Lee, H.-Y., Armbrüster, C.: Understanding Requirements for Textile Input Devices: Individually-tailored Interfaces Within Home Environments.

First technology augmented textiles in form of clothes and furnitures are becoming commercially available. In contrast to the close link between technological development and innovations, future users’ acceptance and usage of such interactive textiles has not been integrated sufficiently, yet. The current study investigates future users’ consumer behavior and acceptance of interactive textiles using a scenario-based conjoint analysis study, which was presented in an online questionnaire ( n = 324 ). Two prototypical interactive textiles were focused on: a smart jacket and a smart armchair. To assess the textile products, the participants had to choose the preferred product alternative consisting each of the acceptance-relevant factors “connectivity”, “input modality”, “feature range”, “usability”, and “ease of cleaning”and their respective levels. The results revealed that the “ease of cleaning” is the most important decision criterion for both textile devices (even more important for the smart jacket), followed by “feature range”, “connectivity”, and “usability”. In contrast, the “input modality” is perceived as least important. The study also identified user profiles based on the projected consumer behavior (“adopters”, “rejecters”, and “undecided”) for both products. Besides the differences in product evaluation and projected consumer behavior, the user groups are significantly influenced by the individual affinity to textiles (both products) and gender (smart jacket). The findings are used to derive design and communication guidelines referring to interactive textiles in order to incorporate users’ needs, wishes, and requirements into future products.</div> </div> <div class="field field--name-field-signature field--type-string-long field--label-hidden field__item">Offermann-Van Heek, J., Brauner, P., Ziefle, M.: Let’s talk about TEX—Understanding consumer preferences for smart interactive textile products using a conjoint analysis approach.
