Claims:1. An apparatus to trigger an action based on a gesture, the apparatus comprising:
a touch sensitive display;
a touch sensor to detect touches and hovers associated with the touch sensitive display; and
a gesture handler including:
an identifier to identify fingers associated with the touches and hovers; and
a gesture detector to determine a gesture associated with the touches and hovers and determine an action associated with the gesture and the identified fingers.
2. An apparatus as defined in claim 1, wherein the gesture handler includes a system interface to transmit the action to an operating system of the apparatus.
, Description:FIELD OF THE DISCLOSURE
[0001] This disclosure relates generally to touch input, and, more particularly, to methods and apparatus to detect touch input gestures.

BACKGROUND
[0002] In recent years, touch input devices, such as touch sensing displays, have increased in quality and popularity. For example, many popular computing devices such as laptop computers, desktop computers, tablet computers, smartphones, etc. have been implemented with touch input devices to accept user input via touch (e.g., via a finger touching the display). Some such touch input devices are capable of sensing multiple touch inputs (e.g., a two-finger input gesture). Additionally or alternatively, some touch input devices are capable of detecting touch input prior to/without the touch input making contact with the touch input device. This type of detection is commonly referred to as hover detection (e.g., detecting a finger that is hovering and/or approaching the touch input device).
