As part of the research project "Secure information networks of small- and medium-sized energy providers" (SIDATE), a survey about the IT security status of German energy providers was conducted. The project itself is focused on the IT security of small- and medium-sized energy providers. In August 2016, 881 companies listed by the Federal Network...

What is end-user development (EUD) and when does a user become an end-user developer? Since the concept of EUD encompasses methods as well as practices of appropriating technology, it is not easy to answer these questions and several researchers already dealt with these issues. Within our chapter we suggest to conceptually extend our understanding...

Mobile devices have conquered nearly all parts of the daily life. These devices support their owners in specific situations, both at work and in leisure contexts, and therefore make it increasingly difficult to keep work and private life separated. Examining the practices around the use of mobile technology has become a topic of some interest as is...

Due to new regulations in Germany energy providers are required to obtain IT security certificates. Especially small and medium-sized energy providers struggle to fulfill these new requirements. Since most of them are in the same situation, we are dealing with the question on how to support their collaboration using a web-based platform. We elicite...

In recent years, platforms such as Arduino have made it easier for makers and hobbyists to create " smart objects " and connected devices. However, there are some unique barriers when developing embedded systems that challenge non-professionals. We derive these barriers from existing literature on end-user-development (EUD) in general and in partic...

Eine sicher funktionierende Energieinfrastruktur ist für fast alle Lebensbereiche unserer heutigen Gesellschaft grundlegend. Damit die Energieversorgung im Rahmen der Energiewende auch nachhaltig sichergestellt werden kann, wird auch im Energiesektor immer mehr Informations-und Kommunikationstechnik (IKT) eingesetzt.

Fragebögen sind ein beliebtes und bewährtes Mittel in Usability-Studien. Sie werden oft im Rahmen von Usability-Tests verwendet. Solche Tests stellen jedoch oft künstliche Situationen dar. Data logging, also das automatische Sammeln von Nutzungsdaten, kann hingegen Einblicke in die Nutzung von Applikationen im echten Nutzungskontext geben. Diese Me...

Increasingly, mobile services are using location-based information provided by GPS sensors. Especially HCI research deals with a growing interest in how people make sense of location-based information while on the move. Mobile user-studies can help to address this black box and provide the opportunity to combine location-based data with context rel...
Conference Paper

With the emergence of smart, sensor-equipped mobile devices, the gathering and processing of data concerning the everyday lifestyles of the people using these devices has become a matter of course within the field of HCI. New standards in mobile technologies provide new opportunities for empirical studies, which allow researchers to explore people’...
Conference Paper

Distributed collaborative applications for supporting complex use cases in mobile environments have to provide contextual information (e.g. presence and group awareness) via their user interface. Social interaction and data sharing - being essential aspects of distributed collaborative applications - typically result in conflicting goals, primarily...

Project
The goal of the project EKPLO is to make use of the potentials of advanced planning and scheduling (APS) systems with a special consideration of the employees as key players in order to establish a collaborative a order and resource planning across supply chains. The resulting system will be called human-centered APS (HAPS). Website: http://ekplo.de
Project
Due to the recent German and European regulations for critical infrastructures, the concerned companies and especially energy providers are required to get certifications for their security. As a consequence in particular small and medium-sized energy providers struggle to fulfil the requirements. Compared to larger providers, there is a lack of financial and human resources which they could utilise for IT security. The aim of the SIDATE project is to develop tools and concepts in order to support small and medium-sized energy providers to continuously improve their security. Since many of them face same challenges, a natural solution to support them is to stimulate inter-organisational collaboration. This should be done by building an inter-organisational collaboration platform for energy providers. The platform should enable the energy providers to share their knowledge about IT security in a structured way. One of the platform’s modules should be a security self-assessment and benchmarking module, so the energy providers can easily assess and compare their security level.
