There aren't many CS classes where you can actually make something and deploy it. This is a great class to have fun making Android apps that you can actually install on your phone. Lecture slides are kinda dry, but he's kind and answer all questions happily. You'll have to read documentations to learn Android basics tho.

Prof. Hollerer is a great professor who obviously cares about his students. However 184 was a heavier class than I expected. Not conceptually difficult, but you make several apps over the course of the quarter and there's a lot of debugging and hacking stuff up involved. Lectures are also a bit dry. Start your projects EARLY!!!!

Super nice professor. Easy class as well.

Awesome class! We had a ton of fun working on Android projects while simultaneously learning about HCI fundamentals. I definitely recommend going to lecture and taking notes. Many of his examples will be on the "final" exam.

hes a pretty good professor. the only thing i didn't really like is that the grading granularity was too low. people who didn't understand the material often got better grades then those who did, but made a minor mistake such as a typo or what not.

Great lecturer. He was able to adapt lectures to discuss the newest technologies. Learned a lot with the projects. Very applicable and useful material for the outside world.

Engaging, knows what he's doing. Has a German accent, still perfectly understandable. Good if you like CS. A little air-headed at times, goes on tangents.
