Research output: Chapter in Book/Report/Conference proceedingConference Contribution (Conference Proceeding)


The development of smart home and ambient healthcare systems benefits from the availability of ground truth data - annotations describing participant actions, such as current state, location or activity. Such annotations are useful to support building and testing systems to automatically extract this information from the data. This paper describes a prototype annotation system based on a Google Wear OS watch, using
tactile input via Graffiti-style on-screen handwriting, combined with unobtrusive haptic feedback to acknowledge the receipt of data.
