Google introduced a new feature. You can now look at the ranking of publication venues by discipline and sub-discipline. The HRI conference is listed at place 9 in the robotics area. The CHI conference is on top in the human-computer interaction ranking. In both disciplines, Google has a problem with “Interaction”, since it declares them to be “Unteraction”. The journal “Human-Computer Interaction” is also not listed. I am not sure if this is due to a lack of h-index or due to some other reason.
