Annotating a physical object with (1) two hardware devices (Adafruit Feather Bluefruit LE Micro Board), each featuring an orientation sensor (BNO055 9-DOF absolute orientation sensor) which detects the rotations of the physical object and of the pointing device, respectively. (2) A graphical software tool which captures annotation activities and displays them on the digital object. The software tool is built as a native application using the Electron framework. It utilizes web technologies like Polymer, three.js and pouchdb.
(3) A server backend (Node.js) connected to a database (CouchDB). It stores the live sessions as well as all object and annotation data, and provides an application programming interface for integrating external data sources.
