Pattern-based mobile device unlocking
A computer-implemented method of authenticating a user with a computing device is disclosed. The method involves displaying a grid of selectable visually-distinguishable graphical elements on a device display, receiving from a user of the device a drawn pattern across the selectable graphical elements, comparing the received drawn pattern to information representing a stored authentication pattern for the user, and unlocking access to functions on the device if the received drawn pattern substantially matches the stored authentication pattern.
1. A computer-implemented method executed by one or more processors, the method comprising:
entering, by a computing device, a locked mode in which access to one or more functions of the computing device is restricted;
receiving, by the computing device and while in the locked mode, a wireless communication;
receiving, by the computing device and while in the locked mode, a first user input; and
displaying, (i) by the computing device, (ii) while remaining in the locked mode, and (iii) in response to the first user input, a lock mode display screen comprising a presentation of current time and a notification indicative of the received wireless communication.
2. The computer-implemented method of claim 1 , wherein the lock mode display screen includes a presentation of instructions for unlocking the computing device.
3. The computer-implemented method of claim 2 , further comprising:
receiving, by the computing device and while the lock mode display screen is being displayed, a second user input;
displaying, by the computing device and in response to receiving the second user input, an unlock entry screen that allows a user to enter an unlock input using touchscreen capabilities of the computing device;
receiving, by the computing device, the unlock input via a touchscreen of the computing device; and
entering, by the computing device and in response to receiving the unlock input, an unlocked mode.
4. The computer-implemented method of claim 1 , wherein the received wireless communication is an indication of an incoming call and the notification comprises a notification of a missed call.
5. The computer-implemented method of claim 1 , wherein the received wireless communication is an indication of a voice message and the notification comprises a notification of the voice message.
6. The computer-implemented method of claim 1 , wherein the received wireless communication is a text message and the notification comprises a notification that the text message has been received since a last time the computing device was in an unlocked mode.
7. The computer-implemented method of claim 6 , wherein the notification further comprises an indication of a sender of the text message and at least a portion of content of the text message.
8. The computer-implemented method of claim 1 , wherein the lock mode display screen further comprises a presentation of a second notification indicative of a scheduled calendar event.
9. The computer-implemented method of claim 1 , wherein the lock mode display screen further comprises a presentation of a second notification indicative of a preset alarm time.
10. The computer-implemented method of claim 1 , further comprising:
receiving, by the computing device and while the lock mode display screen is being presented, a second user input; and
displaying, by the computing device and response to the second user input, additional detail relating to the notification while remaining in the locked mode.
11. The computer-implemented method of claim 1 , wherein the lock mode display screen further comprises a presentation of instructions for placing an emergency call, the method further comprising:
receiving, by the computing device and while the lock mode display screen is being displayed, a second user input; and
displaying, by the computing device and response to the second user input, an emergency call screen, wherein the emergency call screen permits a user to dial a telephone number, and wherein the emergency call screen restricts user input from accessing a contact list stored on the computing device.
12. The computer-implemented method of claim 1 , wherein the notification indicates a number of received messages.
13. A non-transitory computer readable medium storing instructions that, when executed by one or more processors, cause the one or more processors to perform operations comprising:
entering, by a computing device, a locked mode in which access to one or more functions of the computing device is restricted;
receiving, by the computing device and while in the locked mode, a wireless communication;
receiving, by the computing device and while in the locked mode, a first user input; and
displaying, (i) by the computing device, (ii) while remaining in the locked mode, and (iii) in response to the first user input, a lock mode display screen comprising a presentation of a current time and a notification indicative of the received wireless communication.
14. The medium of claim 13 , wherein the lock mode display screen further comprises a presentation of instructions for placing an emergency call, the operations further comprising:
receiving, by the computing device and while the lock mode display screen is being displayed, a second user input; and
displaying, by the computing device and response to the second user input, an emergency call screen, wherein the emergency call screen permits a user to dial a telephone number, and wherein the emergency call screen restricts the user from accessing a contact list stored on the computing device.
