"Tap" refers to an operation in which a user immediately touches the screen using a finger or a touch tool (eg, an electronic pen) and immediately lifts the screen without moving.

"Touch & hold" refers to an operation in which a user holds a touch input for more than a threshold time (for example, 2 seconds) after touching a screen using a finger or a touch tool (for example, an electronic pen). That is, this means that the time difference between the touch-in time point and the touch-out time point is greater than or equal to the threshold time (for example, 2 seconds). In order to allow the user to recognize whether the touch input is a tap or a touch and hold, the feedback signal may be provided visually, acoustically, or tactilely when the touch input is maintained for a threshold time or more. The threshold time may vary depending on implementation.

"Double tap" refers to an operation in which the user touches the screen twice using a finger or a touch stylus.

"Panning" refers to a case where a user performs a drag operation without selecting an object. Panning does not select a specific object, so instead of moving the object within the page, the page itself moves within the screen, or a group of objects moves within the page.

"Flick" refers to the action of a user dragging over a threshold speed (eg, 100 pixel / s) using a finger or a touch tool. The flick may be distinguished from the drag (or panning) based on whether the movement speed of the finger or the touch tool is greater than or equal to the threshold speed (eg, 100 pixel / s).

"Drag and drop" refers to an operation in which a user drags an object to a predetermined position on the screen and releases it using a finger or a touch tool.

“Pinch” refers to an operation in which a user moves two fingers in different directions while touching two fingers on the screen. This gesture is for zooming in or out of an object or page. An enlargement or reduction value is determined according to the distance between two fingers.

"Swipe" is an action of moving a certain distance in the horizontal or vertical direction while touching an object on the screen with a finger or a touch tool. The oblique motion may not be recognized as a swipe event.

The memory 160 may include a voice recognition module (not shown) for recognizing a voice of a user using a voice recognition engine and delivering the recognized voice to the controller 150.

Examples of events generated in the mobile terminal 100 include call signal reception, message reception, key signal input, schedule notification, and the like. The alarm module 164 may output an alarm signal in the form of a video signal through the display unit 121, may output the alarm signal in the form of an audio signal through the sound output unit 122, or the vibration motor 123. The alarm signal can also be output in the form of a vibration signal.

Meanwhile, the alarm module 164 may provide a snooze function. For example, when the user sets an alarm repeat count (for example, five times) or an alarm repeat interval (for example, three minutes), the alarm module 164 may generate an alarm signal a predetermined number (for example, five times) or a predetermined number. Output at intervals (eg, 3 minutes).

Applications stored in the memory 160 may vary. For example, the application DB 165 may include a reminder application, a contact application, a map application, a music application, an e-book application, a health care application, a workout management application, a parenting application, but are not limited thereto.
