Bubble cursor

The bubble cursor dynamically resizes its size to make sure that one target is always selectable.

Bubble cursor is based "The Bubble Cursor" research paper written by Tovi Grossman and Ravin Balkrishnan and published in 2005. 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. Configuration a - show/hide visual grey bubble. s - disable bubble cursor until page is refreshed. All configuration can be changed in extension settings.
