Limited-access state for inadvertent inputs

A computing device comprising:

• a presence-sensitive input device;
• and
• one or more processors operable to:
• while the computing device is operating in a first limited-access state, receive an indication of a first input detected by the presence-sensitive input device;
• responsive to determining that at least one value of a characteristic of the first input exceeds a predetermined characteristic threshold, transition the computing device from operating in the first limited-access state to operating in a second limited-access state, wherein the second limited-access state is different from the first limited-access state;
• while operating in the second limited-access state:
• output, for display, a graphical user interface comprising instructions that specify user-provided input for transitioning the computing device from operating in the second limited-access state to operating in the first limited-access state;
• and
• receive an indication of a second input, the second input being defined by one or more touch events;
• and
• responsive to determining, based at least in part on location information associated with the one or more touch events, that the indication of the second input satisfies a threshold of compliance with the instructions that specify user-provided input for transitioning the computing device from operating in the second limited-access state to operating in the first limited-access state, transition the computing device from operating in the second limited-access state to operating in the first limited-access state.

A non-transitory computer-readable storage medium encoded with instructions that, when executed by one or more processors of a computing device, cause the one or more processors to:

• while operating in a first limited-access state, receive, while the computing device is operating in a first limited-access state, an indication of a first input;
• responsive to determining that at least one value of a characteristic of the first input exceeds a predetermined characteristic threshold, transition the computing device from operating in the first limited-access state to operating in a second limited-access state, wherein the second limited-access state is different from the first limited-access state;
• while operating in the second limited-access state:
• output, for display, a graphical user interface comprising instructions that specify user-provided input for transitioning the computing device from operating in the second limited-access state;
• and
• receive an indication of a second input, the second input being defined by one or more touch events;
• and
• responsive to determining, based at least in part on location information associated with the one or more touch events, that the indication of the second input satisfies a threshold of compliance with the instructions that specify user-provided input for transitioning the computing device from operating in the second limited-access state to operating in the first limited-access state, transition the computing device from operating in the second limited-access state to operating in the first limited-access state.
