CHARACTER RECOGNITION ON A COMPUTING DEVICE

摘要

In some embodiments, a device performs character recognition based on spatial and temporal components of touch input detected on a touch-sensitive surface. In some embodiments, a device provides feedback about handwritten input and its recognition by the device. In some embodiments, a device presents a user interface for changing previously-inputted characters.

主权项

1. An electronic device, comprising:
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:
receiving an indication of a first input that includes movement of a contact detected on a touch-sensitive surface of a device, wherein:
the movement of the contact comprises a first stroke, andthe first stroke has a spatial component and a temporal component;determining a first probability that the first stroke corresponds to a first character based on the spatial component of the first stroke;determining a second probability that the first stroke corresponds to the first character based on the temporal component of the first stroke; anddetermining an aggregate probability that the first stroke corresponds to the first character based on the first probability and the second probability.
