I don't know about courses but I read The Design of Everyday Things by Donald Norman more than 10 years ago and it profoundly changed my life.

Obviously it doesn't only deal with UI design but I really recommend it if you're looking for a place to jump off from.

Be warned, once you read it you'll find yourself becoming extraordinarily annoyed by certain types of doors.
