Your interpretation is correct: you touch the word you want to look up for about a second. As a result of that, the word is selected and a menu bar is displayed at the top of the screen. Then you briefly touch the menu option for the dictionary (other options are that you can highlight the word, add a comment or google the word). Then in about another second the dictionary entry comes up. The whole process takes me about 3 seconds. It does not seem to make any difference whether it is a long or a short word.

The dictionary window covers about one third of the screen, and you can keep it open while reading, so that you can look up other words in the text simply by tapping them once. The dictionary window overlaps either the top or bottom part of the text, but you can easily move it from top to bottom or from bottom to top with a simple tap. I find that a convenient way of working when I'm reading a text in which I need to look up a lot of words.

Of course, in the end a lot depends on the quality of the dictionaries, and once again, I cannot promise you that the ones you will need are as good as the ones that I am using for other languages.
