"Touch End" refers to the moment when a touch interaction on a device, such as a smartphone or tablet, is completed. This can occur when a user lifts their finger off the screen after tapping, swiping, or dragging. The device registers this action and responds accordingly, such as opening an app or scrolling through content. In the context of user interface design, understanding "Touch End" is crucial for creating responsive and intuitive experiences. Designers must ensure that the actions triggered by a "Touch End" event are clear and provide immediate feedback to the user, enhancing overall usability and satisfaction with the device.
