Digital Ink and annotations in e-teaching of advanced mathematics

Increasingly in lectures and seminars, the main presentation is projected from a computer: asides (and sketches) are handwritten, usually on a separate physical whiteboard. With distributed multi-nodal remote collaborative teaching via Access Grid, annotation and highlighting needs to be provided electronically. We discuss use of digital ink and annotations – for asides (including examples and sketches) and highlighting during the lecture (laser pointers are not effective in Access Grid Rooms): with a TabletPC (on pdf files using PDF Annotator) and within the Windows system (on Word, PowerPoint and Excel); within Maple and with an interactive whiteboard. We demonstrate an example of marking remote student work (handwritten, scanned as a pdf file and using PDF Annotator)…
