How Correct and Defect Decision Support Systems Influence Trust, Compliance, and Performance in Supply Chain and Quality Management – A Behavioral Study Using Business Simulation Games philipp Sat, 08/22/2020 - 18:14

Abstract

Supply Chains and production networks are complex sociotechnical cyber-physical systems whose performance is determined by system, interface, and human factors. While the influence of system factors (e.g., variances in de- livery times and amount, queuing strategies) is well understood, the influence of interface and human factors on supply chain performance is currently insuffi- ciently explored. In this article, we analyze how performance is determined by the correctness of Decision Support Systems and specifically, how correct and defect systems influence subjective and objective performance, subjective and objective compliance with the system, as well as trust in the system. We present a behavioral study with 50 participants and a business simulation game with a market driven supply chain. Results show that performance (-21%), compliance (-35%), and trust (-25%) is shaped by the correctness of the system. However, this effect is only substantial in later stages of the game and occluded at the be- ginning. Also, people’s subjective evaluations and the objective measures from the simulation are in congruence. The article concludes with open research questions regarding trust and compliance in Decision Support Systems as well as actionable knowledge on how Decision Support Systems can mitigate supply chain disruptions.

Invisible Touch! – Design and Communication Guidelines for Interactive Digital Textiles Based on Empirical User Acceptance Modeling philipp Thu, 08/20/2020 - 19:20

Abstract

Interactive digital textiles are both light and shadow in regard to users’ perception and technology acceptance. 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.

What is Hip ? – Classifying Adopters and Rejecters of Interactive Digital Textiles in Home Environments philipp Thu, 08/20/2020 - 19:15

Abstract

The omnipresence and familiarity of textiles in combination with the integration of invisible sensors, actuators, and information and communication technology under the term “interactive digital textiles” offer the potential of bridging the gap between age, the aging-population, and latest information and communication technology. 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.

Guidelines for Integrating Social and Ethical User Requirements in Lifelogging Technology Development philipp Thu, 08/20/2020 - 19:09

Abstract

Lifelogging technologies have the potential to facilitate and enrich the everyday life of younger as well as older people. On the one hand, tracking and logging of data about activities and behavior support an active lifestyle. On the other hand, tracking medical data and movements support increasing safety by detecting, e.g., emergencies or falls. From a technical perspective, a variety of technologies enable lifelogging and are already available on the market. Instead, there is very little knowledge about the perception and acceptance of lifelogging technologies from users' socio-ethical perspective. Hence, this paper presents research results from four online survey studies (n = 1107) aiming at covering a broad range of lifelogging applications and reaching diverse target groups. Being based on insights gathered from the quantitative data collection, this paper derives guidelines for integrating ethical and social perspectives in lifelogging technology development and emphasizes gaps within the research landscape regarding its perception and acceptance.

Wind of change? Attitudes towards aging and use of medical technology philipp Thu, 08/20/2020 - 18:43

Abstract

Shifts in demographic developments have led to changed needs and requirements in healthcare. Rising life expectancy and improved medical healthcare enable a more independent and healthier lifestyle of (older) persons, but also changes expectations and perceptions of aging, and health-supporting technologies. Knowledge about attitudes towards aging, medical assistive technologies, and impacting user factors (especially age and health status) is limited with regard to a broad sample of participants. In the present study (N=585), we therefore examined in an online-survey current attitudes towards aging and quality of life in older age, as well as perceptions and acceptance of health-supporting technologies, taking age and health status as user factors into account. Results revealed significant effects of age and health condition on the perception of life quality in older age. In addition, positive perceptions of aging, technology acceptance, as well as benefits and barriers were signific antly influenced by the respondents’ age. In contrast, health status significantly affected the negative perceptions of aging. Under impacts of age and health condition as user factors, results of the study allow a deeper understanding of changing patterns of perceived aging and prevailing opinions regarding acceptance of medical technology.

Age, Gender, and Technology Attitude as Factors for Acceptance of Smart Interactive Textiles in Home Environments - Towards a Smart Textile Technology Acceptance Model philipp Thu, 08/20/2020 - 18:28

Abstract

Smart interactive textiles are the next frontier of ubiquitous computing and may serve as novel and accepted interfaces that go beyond conventional human-computer interaction. 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'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.

Projecting Efficacy and Use of Business Simulation Games in the Production Domain Using Technology Acceptance Models philipp Thu, 08/20/2020 - 17:00

Abstract

Globalized markets, product complexity, and increased requirements on quality lead to growing complexity of business and manufacturing processes. Game-Based learning environments and business simulation games offer great potential to prepare employees the increasing complexity. As it is unclear who profits most from these learning environments, we did a study with 66 partici- pants on a game for conveying Production Planning and Control and Quality Management. In our research model we combined personality attributes and two common technology acceptance models to determine factors projecting perfor- mance in the game and projected later use of business simulation games in gen- eral. We found that main drivers for usage are performance expectancy and trans- fer of skill, i.e., the perceived applicability of the learned knowledge and skills for the later work. The attained performance is unrelated to the projected use. The article concludes with guidelines to increase the likelihood for the later use of business simulation games and for increasing their overall efficacy.

Intentions to Use Smart Textiles in AAL Home Environments: Comparing Younger and Older Adults philipp Thu, 08/20/2020 - 16:20

Abstract

The vision of ubiquitous computing is increasingly picking up pace. 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.

Understanding Requirements for Textile Input Devices: Individually-tailored Interfaces Within Home Environments philipp Thu, 08/20/2020 - 15:31

Abstract

In the last few years, an increasing public awareness regarding the consequences of the demographic change can be observed in many countries, which is imposing considerable challenges on future health care systems in the next decades. 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.

Exergames for Elderly in Ambient Assisted Living Environments - Determinants for Performance Technology Acceptance philipp Tue, 08/18/2020 - 14:32

Abstract

Ambient Assisted Living environments (AAL) offer a solution to face the demographic change and by supporting elderly and chronically ill people inside their own home environments. Serious and pervasive games can change people’s attitudes and can promote healthy behavior. However, both concepts are rarely combined and the integration of both concepts is insufficiently explored. We present a user study (n=64) of an Exergame for Ambient Assisted Living Environments with the research foci performance and acceptance. Age is the predominant factor for performance, while the intention to use is determined by gaming frequency. Neither technical self-efficacy, nor age had considerable influence on these measures. Excitingly, the interaction with the game had a considerable positive effect on the participant’s perceived health and pain. The study shows that Exergames in Ambient Assisted Living environments are a viable solution to support the mobility of people in an aging society.
