Starting 1st April 2013 and for the third time, Stanford / Coursera are running their free Human Computer Interaction (HCI) course. Based on previous feedback, a few changes this years; they've revised the assignments, peer assessment, and overall experience it seems. Also, like last time, you can submit assignments in English or Spanish.

p.s. Stanford HCI seminar videos are online at http://hci.st/seminar
I'll be signing up this year. Something else to squeeze into the diary. Yum yum.
