Abstract: Methods, devices and systems for providing a graphical user interface (GUI) including a representation of a keyboard are disclosed. Some examples may involve controlling a display system to present the GUI, including the representation of the keyboard, in at least a portion of an active force sensor area. Some examples may involve receiving, from a touch sensor system, an indication of a touch in a keyboard location of the GUI and receiving, from a force sensor system, an indication of an applied force. Some examples may involve determining whether the applied force is at or above a first force threshold and controlling keyboard functionality corresponding with the GUI according to whether the applied force is at or above the first force threshold.

Abstract: Some disclosed methods may involve receiving an indication of a digit touching a surface of an apparatus in an active fingerprint sensor area, obtaining current fingerprint image data from the digit and performing a first authentication process based, at least in part, on the current fingerprint image data. Responsive to determining that the first authentication process is an unsuccessful authentication process, some methods may involve obtaining non-digit image data after the digit has been removed from the surface, performing a second authentication process based, at least in part, on the non-digit image data and providing a notification regarding the outcome of the second authentication process. In some examples, the non-digit image data may be obtained and the second authentication process may be performed without providing a notification regarding the unsuccessful outcome of the first authentication process.

Abstract: Methods, devices and systems for controlling a fingerprint sensor system are disclosed. Some examples involve receiving a contact indication corresponding to a contact of an object with a surface of an apparatus and determining, responsive to the contact indication, multiple force values corresponding to contact of the object with the surface during a force monitoring time interval. Some examples involve determining whether at least a plurality of the multiple force values exceeds a force threshold and controlling a fingerprint sensor system based, at least in part, on whether at least the plurality of the multiple force values exceeds the force threshold.
