Bubble cursor is a target acquisition technique based on area cursors. It improves upon area cursors by dynamically resizing its activation area depending on the proximity of surrounding targets, so that only one target is selectable at any time.

It works well with all pointing devices and works in many situations that area cursors cannot.

It allows users to move freely around their page and target multiple locations at the same time.

It can be used in all fields with a pointing device.

It is not based on event listeners.

It is based on the page dimensions and the mouse position.
