Devices and methods for processing touch inputs

An electronic device, comprising:

• a display;
• a touch-sensitive surface;
• one or more processors;
• memory;
• and
• one or more programs, wherein the one or more programs are stored in the memory and configured to be executed by the one or more processors, the one or more programs including instructions for:
• displaying a user interface at a first display rate;
• while displaying the user interface in accordance with the first display rate:
• detecting movement of a touch input, including detecting the touch input at a first set of sequential locations on the touch-sensitive surface, wherein the first set of sequential locations includes a plurality of locations on the touch-sensitive surface;
• and
• predicting for the touch input a first set of one or more predicted locations on the touch-sensitive surface based on multiple locations in the first set of sequential locations;
• and
• updating the user interface in accordance with the first set of one or more predicted locations of the touch input on the touch-sensitive surface, wherein updating the user interface in accordance with the first set of one or more predicted locations includes:
• in accordance with a determination that there is a first confidence value in the prediction of predicted locations, the user interface is updated based on a first number of predicted locations;
• and
• in accordance with a determination that there is a second confidence value in the prediction of predicted locations, wherein the second confidence value is lower than the first confidence value, the user interface is updated based on a second number of predicted locations that is less than the first number of predicted locations.

A non-transitory computer readable storage medium storing one or more programs, the one or more programs comprising instructions, which, when executed by an electronic device with a display and a touch-sensitive surface, cause the electronic device to:

• display a user interface at a first display rate;
• while displaying the user interface in accordance with the first display rate:
• detect movement of a touch input, including detecting the touch input at a first set of sequential locations on the touch-sensitive surface, wherein the first set of sequential locations includes a plurality of locations on the touch-sensitive surface;
• and
• predict for the touch input a first set of one or more predicted locations on the touch-sensitive surface based on multiple locations in the first set of sequential locations;
• and
• update the user interface in accordance with the first set of one or more predicted locations of the touch input on the touch-sensitive surface, wherein updating the user interface in accordance with the first set of one or more predicted locations includes:
• in accordance with a determination that there is a first confidence value in the prediction of predicted locations, update the user interface based on a first number of predicted locations;
• and
• in accordance with a determination that there is a second confidence value in the prediction of predicted locations, wherein the second confidence value is lower than the first confidence value, update the user interface based on a second number of predicted locations that is less than the first number of predicted locations.
