Abstract
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.
Claims18
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:
- generating a user interface for display on a display, wherein the user interface includes a gesture display region and a text entry region;
- while the user interface is displayed on the display, receiving an indication of a first input that includes movement of a first contact detected on a touch-sensitive surface;
- in response to receiving the indication of the first input:
- displaying a representation of the movement of the first contact in the gesture display region;
- and
- determining a first character that corresponds to the movement of the first contact;
- while displaying the representation of the movement of the first contact in the gesture display region, detecting an end of the first input;
- and
- in response to detecting the end of the first input:
- displaying the first character in the text entry region;
- and
- shifting the gesture display region with respect to the text entry region.
A method comprising:
- at an electronic device with one or more processors and memory, the electronic device in communication with a display and a touch-sensitive surface:
- generating a user interface for display on the display, wherein the user interface includes a gesture display region and a text entry region;
- while the user interface is displayed on the display, receiving an indication of a first input that includes movement of a first contact detected on the touch-sensitive surface;
- in response to receiving the indication of the first input:
- displaying a representation of the movement of the first contact in the gesture display region;
- and
- determining a first character that corresponds to the movement of the first contact;
- while displaying the representation of the movement of the first contact in the gesture display region, detecting an end of the first input;
- and
- in response to detecting the end of the first input:
- displaying the first character in the text entry region;
- and
- shifting the gesture display region with respect to the text entry region.
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 one or more processors and memory, the electronic device in communication with a display and a touch-sensitive surface, cause the electronic device to perform a method comprising:
- generating a user interface for display on the display, wherein the user interface includes a gesture display region and a text entry region;
- while the user interface is displayed on the display, receiving an indication of a first input that includes movement of a first contact detected on the touch-sensitive surface;
- in response to receiving the indication of the first input:
- displaying a representation of the movement of the first contact in the gesture display region;
- and
- determining a first character that corresponds to the movement of the first contact;
- while displaying the representation of the movement of the first contact in the gesture display region, detecting an end of the first input;
- and
- in response to detecting the end of the first input:
- displaying the first character in the text entry region;
- and
- shifting the gesture display region with respect to the text entry region.
