Abstract: An electronic device with a display and a touch-sensitive surface displays a first authentication user interface on the display, the first authentication user interface including a text entry field for entering a text-based authentication code; detects a first input by a user on the touch-sensitive surface while displaying the first authentication user interface; in response to detecting the first input, displays a second authentication user interface on the display, distinct from the first authentication user interface, the second authentication user interface configured for entering a gesture-based authentication code; while displaying the second authentication user interface, detects one or more gestures by the user at locations on the touch-sensitive surface that correspond to locations on the second authentication user interface; and authenticates the user in accordance with a determination that the detected one or more gestures correspond to a gesture-based authentication code for the user.

Abstract: Techniques are provided for entering and saving a gesture on a touch-sensitive display device. In one embodiment, the device displays an array of visible graphical elements and may detect a gesture based on a user's touch of the visible graphical elements as well as on hidden areas not displayed to the user. For example, the device may detect a user's touch over hidden dots between the visible graphical elements or through hidden lines connecting the visible graphical elements. Some embodiments may include algorithms for improving accuracy in detecting the intended gesture. For example, the device may estimate possible or probable paths based on a current user touch position. In some embodiments, the visible graphical elements may be illuminated when a touch of the visible graphical elements is detected, or a disc representing a user's touch may be displayed as the user enters a gesture.

Abstract: Techniques are provided for entering, verifying, and saving a gesture on a touch-sensitive display device. In one embodiment, the device displays a gesture entry screen where a user enters a gesture. The device estimates the entered gesture and displays the estimated gesture on a gesture replay screen. The estimated gesture may be replayed repeatedly until stopped, and the device may display a gesture verification screen where the user may reenter the gesture. The device verifies if the re-entered gesture is substantially the same as the original estimated gesture. Some embodiments include a visible trace following a user's touch on the touch-sensitive display, where the trace may change in color and/or length depending on the speed, duration, and/or complexity of an entered gesture. Some embodiments include display indicator(s) (e.g., a strength bar, color change, timer, etc.) to indicate the strength and/or elapsed time during an entry or replay of a gesture.
