- AI-based media disruption and generative artificial intelligence
- Innovative media technologies (augmented reality, chatbots, deepfakes)
- User experience research
- Willingness to pay and consumer behavior in the mobile market
- Technology acceptance
Research Center Smart Systems for People and Technology (SSMT)
The CAEBUS team is part of the DIGITAL BUSINESS & E-GOVERNMENT working group at the university's internal research center SSMT.
The research focus "Smart Systems for People and Technology" reflects a strength of Hochschule RheinMain: the interdisciplinary and holistic approach to practical research questions. At the heart of the research are smart, i.e. safe IT systems that adapt to the individual characteristics and environments of users and are pleasant to use. This requires the interaction of various sub-disciplines of computer science.
The WG DIGITAL BUSINESS & E-GOVERNMENT forms the interface between the faculties of DCSM and WBS.
