It's always nice to be cited and Birgit Loch and Christine McDonald have done so in "Synchronous Chat and Electronic Ink for Distance Support in Mathematics," Innovate, Feb/March 2007. They cite my 2004 work on Virtual Office Hours for students at a distance which pointed out that economists, statistician and mathematicians can't effectively communicate at a distance with the normal tools of a computer, with type and the mouse. They show the use of digital ink in MSN Messenger and show examples of mouse drawings. I would like to see this used with Tablet PCs where the precision of writing could improve with the use a pen. I am going to have to install MSN and give it a try. The advantage of this over Adobe Connect? It's free!
