There are many ways to anchor digital information in the physical world. Common technologies today include NFC tags, QR codes, location and image recognition. As they rely on a mobile device to present information, they require user interaction before they present any up-to-date information – which could motivate and facilitate engagement in first place.
To address this problem we combine a marker with a small display. The display provides dynamic information upfront and enables potential users to make an informed decision about their engagement. In addition, it can give dynamic feedback and show a trace in the physical environment after interaction took place.
Ubiquitous annotation is a generic concept with a wide range of applications. We focus in particular on social object annotation, where people rate and comment on physical objects and places.
