Still Searching or Have You Found It Already? – Usability and Web Design of an Educational Website
(2018)
Background: Apart from a straight-forward and intuitive operability an appealing design determines the success of a website equally well. For this reason, the selection of images and navigation bars plays a determining role. The eye tracking method proved to be appropriate in order to verify the usability of websites. Objectives: The aim of the study was to improve the usability of the website of an educational institute for trainees as target group. Methods/Approach: For this purpose, the use of an eye-tracking technology was combined with a survey. The eye-tracking study was implemented task-oriented. Test persons were asked to search for particular courses within this institute. Results: This approach in combination with a subsequent questionnaire resulted in tangible indications of search patterns of the test group. Furthermore, their perception and their appraisal of the usability as well as the web design was analysed. Even though most tasks were accomplished effectively and efficiently with a positive user feedback, a potential for improvement was detected, in particular with regard to the images and the location of the search field. Conclusions: The selected choice of methods enables researchers and web designers to derive recommendations for the orientation, structure, optimisation and comprehensibility of a website.
Mind the gap
(2015)
Sustainability is a growing megatrend in our society entailing an increasing importance of sustainable consumption. Consumers associate sustainable products with ecological and regional production including a high credibility. In order to take advantage of this trend manufacturers of sustainable foods must communicate the sustainability of their products via packaging and displays at the point of sale. The objective of this article is to examine how the design of display elements succeeds in conveying sustainability for a new organic juice. In addition, the perception of individual design elements of sustainable products is determined. To this end, a field study was carried out in a supermarket combining eye-tracking technology with a survey of 32 customers. At the entrance, customers were asked to buy a variety of the newly introduced "Emsländer" organic juice, and then participate in the survey. The results demonstrate that customers with a positive attitude towards sustainable food fixate individual display elements referring to sustainability components for longer and remember product features better. Hence, the positive attitude towards sustainable food results in a higher visual attention at the point of sale. These findings provide recommendations for the design of the display.
DIGI4Teach - Handbook
(2023)
One of the important outputs of our DIGI4Teach consortium is this Handbook, which consists of two parts. Part A contains an analysis of the most important descriptive research results conducted within the DIGI4Teach Erasmus+ project regarding the use of digital technology in teaching economic disciplines in partner countries. Part B contains twelve case studies from different areas of economics and business (accounting, finance, marketing, tourism and trade) that were prepared using various digital tools and they can be freely used in classes or other forms of education.
Design knowledge on smart glasses-based systems is scarce. Utilizing literature analysis on software development publications, insights from the design and implementation of four smart glasses-based systems and expert interviews, we elicited 16 design principles to provide guidance in the development of future service support systems. Heuristic Theorizing is an abductive Design Science Research method, hitherto far too little known or little noticed, which was applied to conduct the research. We contribute to theory and practice with applicable design principles to support the development of smart glasses-based systems. Phenomena known to have an impact on the adoption of smart glasses are addressed by these design principles.
The development of augmented reality glasses is still ongoing and faces barriers in diffusion and concerns about their impact on users, organizations and society. The study aims to find sufficient solutions for this struggling digital innovation and to provide guidance for the implementation of augmented reality glasses in design-oriented projects. During a 3-year consortium research, acceptance and privacy have been identified as major phenomena that influence the adoption of augmented reality glasses in the logistics domain. To forge ahead digital innovation research, the focus of the presented research lies on the diffusion of this technology with design knowledge for the development of augmented reality glasses-based systems. Evidence and artifacts contribute to the still limited knowledge of system design based on augmented reality glasses from a domain-specific instantiation and an implementation framework.
