The Bubble Cursor
The bubble cursor is a target acquisition technique based on area cursors. The bubble cursor improves upon area cursors by dynamically resizing its activation area depending on the proximity of surrounding targets, such that only one target is selectable at any time. Empirical studies show that the bubble cursor significantly outperforms the point cursor, and that bubble cursor performance can be accurately modeled and predicted using Fitts' law.
