Interesting. My average time was actually slightly faster when the bubble cursor was off, but I think that was only because it made the teal bubble much easier to find. The clicking itself seemed significantly easier with the cursor on, especially when the teal bubble was small. By the way, the selection method here is not complicated: a click just selects the nearest bubble. The interesting part is the interface. Also, I'm wondering how this could be adapted to a more realistic context: say we have a large rectangle with a bunch of smaller rectangles inside it (e.g., a window with icons in it). The typical rule is that a click inside the large rectangle, that is not also inside a smaller one, counts as a click on the large rectangle. Now, could we adapt the bubble cursor to this situation? You can't differentiate between a click on a small rectangle and a click on the large one by the nearest criterion, since all clicks will generally be inside the larger rectangle.
