The present disclosure relates to user interfaces for receiving user input. In some examples, a device determines which user input technique a user has accessed most recently, and displays the corresponding user interface. In some examples, a device scrolls through a set of information on the display. When a threshold criteria is satisfied, the device displays an index object fully or partially overlaying the set of information. In some examples, a device displays an emoji graphical object, which is visually manipulated based on user input. The emoji graphical object is transmitted to a recipient. In some examples, a device displays paging affordances that enlarge and allow a user to select a particular page of a user interface. In some examples, the device displays user interfaces for various input methods, including multiple emoji graphical objects. In some examples, a keyboard is displays for receiving user input.

A touchpad and its force-sensing data correction method are provided. The touchpad has a force-sensing layer and a touch-sensing layer. The force-sensing layer has multiple force-sensing points. The touch-sensing layer has multiple touch-sensing points. One force-sensing point corresponds to n touch-sensing points. The force-sensing information received by the force-sensing layer is adjusted by using the touch-sensing information received by the touch-sensing layer, so that the resolution of the adjusted force-sensing information is higher than the resolution of the original received force-sensing information. In this way, the purpose of calibrating the force-sensing information is achieved, so as to improve the accuracy of determining the force applied by the object during the operation of the touchpad.
