This document discusses attention data and services, including a demo of current services and potential future demand from end users. It outlines key principles of attention data such as users owning and controlling their data, being able to move it securely between services, participating in an attention-based economy, and having transparency in how their data is used. Current attention recording and analysis services are demonstrated with a discussion of what new services may emerge and how attention data could flow and be analyzed to meet future user needs in a user-centric, open, and innovative way.
