The International Workshop on Symbiotic Interaction is the primary venue to present scientific works dealing with the symbiotic relationships between humans and computers and to discuss the nature and implications of such relationship, including ethics. The idea of symbiotic systems put forward in this workshop capitalizes on the computers’ ability to implicitly (even subliminally) detect the users’ goals, preferences or/and psycho-physiological states and modify its output accordingly. The workshop comes back to Padua this year after three successful editions in London, Helsinki and Berlin and extends its scope to qualitative research.
The emphasis is on user-driven research on symbiotic systems, adaptive systems, implicit input data, physiological computing and BCI, but also on understanding more deeply the nature of the interdependence and agency between computers and humans more broadly.

Topics can regard but are not limited to:
• Multimodal input for symbiotic systems
• Design and evaluation approaches: relevant dimensions for designing and evaluating a usable and satisfactory symbiotic system
• Context-aware and user-aware adaptive solutions
• Ethic issues and responsibilities (transparency, control, automaticity, profiling, agency, …)
• Symbiotic individual and collective behavior and structures
• Applications of symbiotic interaction (traffic, work and organizations, security, …)
• Transparent visualizations and feedback
• Symbiosis and persuasion
• Intelligent assistants using implicit data
• Recommender systems using implicit data
• Modeling users’ affective states
• Prediction of users’ goals and information relevance
• User models in collective symbiotic systems
• User’s perception of adaptive systems and intelligent interfaces: trust, blame, performance, facilitation
• Symbiosis in assistive technologies

The proceedings will be published by Springer, in the Lecture Notes on Computer Science series.
