    Digitalisation for sustainability? Challenges in environmental assessment of digital services
    (INFORMATIK 2017, 2017) Pohl, Johanna; Finkbeiner, Matthias
    The expectations for Information and Communication Technology (ICT) to tackle climate change are massive, but successful implementation is by no means assured. Contrasting resource saving potential of ICT, energy and resource demand of end-user devices and digital services are growing. The overall question is, how great must the net enabling effects of specific digital services be in order to balance or exceed direct effects of ICT devices and the infrastructure used. To contribute to a more coherent assessment of digitalisation´s implications for sustainability, the authors suggest the following points: to cover all potential impacts, an environmental assessment of ICT has to follow a life cycle approach. Both ICT infrastructure as well as changing use patterns (direct rebound effects) have to be included into the system boundaries; only addressing energy issues is not sufficient. In addition, the material basis and resulting environmental and social impacts from mining, production and disposal have to be addressed.

    IT-getriebenes Instandhaltungsmanagement im After Sales Bereich
    (HMD Praxis der Wirtschaftsinformatik: Vol. 54, No. 3, 2017) Spreitzer, Sabrina; Mladenow, Andreas; Wagner, Gerold
    Eine der Hauptaufgaben des After Sales Service ist die Instandhaltung, und besonders in diesem Bereich ist zu erwarten, dass sich durch die derzeit voranschreitende Entwicklung von intelligenten Systemen und die dadurch bedingte steigende Maschinenvernetzung langfristige Veränderungen für den Unternehmensbereich ergeben werden. Der Hauptfokus der Forschung liegt im Umfeld der intelligenten Instandhaltungssysteme zumeist auf dem Entwicklungs- und Produktionsbereich, weshalb die bevorstehenden Veränderungen im After Sales Service teilweise noch schwer greifbar sind. Die vorliegende Studie analysiert anhand einer Case Study („multiple-case design“) potenzielle Auswirkungen intelligenter Instandhaltungskonzepte auf die Arbeitsweise des After Sales Service. Neben der zukünftigen Einbindung von Augmented Reality und Remote-Service Einsätzen stellt das Management von Daten und Wissen in der zukünftigen Arbeitswelt eine wichtige Stütze für den Erfolg der Instandhaltung dar. Durch die steigenden Datenmengen (Big Data) ist ein Trend zur Zentralisierung der Aufgaben erkennbar. Zudem werden auch interdisziplinäre Kenntnisse in den Bereichen Ingenieurswesen, Datenmanagement, Informationstechnologie und Betriebswirtschaft von Mitarbeitern erwartet, und der inhaltliche Aufgabenschwerpunkt verschiebt sich teilweise in Richtung IT-basierter Instandhaltung.AbstractOne of the primary tasks of After Sales Service is maintenance. It can be expected, especially in this area, that the current development of intelligent systems and the consequential increase of machine networking will result in long-term changes for a company’s business. The main focus of research on intelligent maintenance systems lies in the area of development and production which is why imminent changes in the after sales service are still difficult to grasp. Based on a case study (“multiple-case design”), the present study analyzes the potential impact of intelligent maintenance concepts on the operation of after sales service. In addition to the future integration of augmented reality and remote service assignments, the management of data and knowledge is an important success factor of maintenance in the modern working world. The increasing data volume (big data) indicates a trend towards centralization of tasks. In addition, interdisciplinary knowledge in the fields of engineering, data management, information technology, and business management is expected from employees, and the main focus of the task is shifting towards IT-based maintenance.

    Smart Home Medical Technologies: Users’ Requirements for Conditional Acceptance
    (i-com: Vol. 15, No. 1, 2016) Himmel, Simon; Ziefle, Martina
    One mega challenge for the next decades is the aging of populations in western societies. Ambient Assisted Living (AAL) Technologies provide solutions for these challenges of demographic change. Elderly people living independently in their homes can be monitored for health reasons with integrated information and communication technologies (ICT) to get help in case of emergencies. From the user-centered approach, acceptance of these solutions is crucial. In his work, we focus on the effects of 5 domestic spaces and 3 integrated ICT on acceptance and the influence of user factors. We consider two samples from 2010 (n = 100) and 2015 (n = 148). Results show that visual monitoring is accepted least, positioning best. The role of private and public rooms has a strong influence on acceptance. Also, the type of technology as well as the interaction of technology and room have a strong impact, whereas user factors play only a minor role for AAL acceptance.

    Use of Information and Communication Technology in Healthcare Context by Older Adults in Germany: Initial Results of the Tech4Age Long-Term Study
    (i-com: Vol. 16, No. 2, 2017) Mertens, Alexander; Rasche, Peter; Theis, Sabine; Bröhl, Christina; Wille, Matthias
    In 2016 the interdisciplinary research team Tech4Age started its long-term survey to evaluate the use of information and communication technology (ICT) by older adults () in Germany. This study focuses on the use of ICT devices and applications, the evaluation how these devices are operated in terms of ergonomic hand positions, the investigation of health information usage as well as technology affinity, health literacy and computer literacy. The first run of the Tech4Age long-term study was done by sending a paper-based questionnaire to 5,000 individuals older than 60 years randomly selected from the total German population and equally locally distributed within Germany. Responses were collected from N = 551 participants with a mean age of 69.17 years (SD = 5.787). The gender ratio of the sample is balanced, including 51.3% male and 48.7% female. Results provide descriptive insights into technology usage and knowledge about influencing factors. Older adults already use modern ICT on a large scale, for example to do online banking or for mobility reasons (navigation, booking tickets, etc.), but health-related ICT products and applications have been used less, mainly due to mistrust. Investigation of health information usage showed that doctors and pharmacists are the main sources older adults rely on. Two thirds of all participants were satisfied with general information they got about health. The evaluation of the ergonomic use of ICT devices revealed a common way of use, namely that a majority of older adults prefer to use their ICT devices in the case of a small display in portrait mode and in the case of larger displays in portrait as well as landscape mode. Touch input is always performed with a finger or the second hand, the one not holding the device. The article will present and discuss the results in detail.
