Social Psychological Aspects of Smart Homes


SPASH is a project aiming at introducing metrics from social psychology into the field of usability engineering and UX design.


Modern technology, especially services like intelligent personal assistants and smart homes can reach high complexity of interaction. Such interaction spaces can hardly be assessed with traditional usability studies and metrics that have been used for years in human-computer interaction.


While human-computer interaction has been less complex and flexible in the past, the rise of ever more powerful interfaces with vast and flexible functionality spaces requires new viewpoints. The SPASH project aims at transferring concepts from social psychology to human-machine interaction reseach.


Project Leader: Patrick Ehrenbrink

Project Duration: 24M

The SPASH project is funded by the Bundesministerium für Bildung und Forschung, Software Campus, under grad no. 01IS12056.
