The document describes the CEEDs (Collective Experience of Empathic Data Systems) project. CEEDs is developing a framework to allow people to consciously experience and interact with large datasets through synthetic reality systems. It monitors signals in users' unconscious responses like physiological measurements and behaviors to guide them to interesting areas in data visualizations. The project has 16 research partners across Europe and aims to build systems that leverage implicit and explicit user responses to support discovery and personalized experiences. Potential applications discussed include using CEEDs for neuroscience research, consumer preferences modeling, and informing product design. The document concludes with a workshop challenge to imagine innovative usage scenarios for CEEDs.
