Abstract

Input mechanisms can employ a case for an electronic device that provides input capabilities to enhance the user experience when using the case in concert with the electronic device. For example, a case can provide an electromechanical touch sensor to provide the user with an input mechanism that does not require actuation of the button of the electronic device. The electronic device, upon detecting the presence of the case, can disable one or more buttons and perform actions corresponding to the buttons when signals are received from the case.

First claim

What is claimed is:

1 . An electronic device for coupling to a case, the electronic device comprising:
a button configured to detect a first input at the button; a device communication interface configured to:
detect the case when the electronic device is coupled to the case, the case comprising an electromechanical touch sensor positioned to overlap the button when the electronic device is coupled to the case; and
receive a signal from the case, the signal corresponding to a second input received at the case; and
a processor configured to:
when the electronic device is not coupled to the case and when the button detects the first input at the button, perform an action associated with the button; and
when the electronic device is coupled to the case, disable the button of the electronic device and perform the action associated with the button only when the signal is received from the case.

2 . The electronic device of claim 1 , wherein the button comprises a strain gauge configured to generate a signal upon depression of the button.

3 . The electronic device of claim 1 , wherein the action associated with the button is to change a speaker volume setting of the electronic device.

4 . The electronic device of claim 1 , wherein the device communication interface comprises a near-field communication (NFC) coil.

5 . The electronic device of claim 1 , wherein the device communication interface is further configured to receive an identification signal from the case, the identification signal comprising a command to disable the button of the electronic device while the case is coupled to the electronic device.

6 . The electronic device of claim 1 , wherein the device communication interface is further configured to receive an authentication signal from the case, the authentication signal corresponding to an authentication of a user, and the processor is further configured to unlock a feature of the electronic device in response to the authentication signal.

7 . An electronic device for coupling to a case, the electronic device comprising:
a button configured to detect an input; a device communication interface configured to receive a signal from the case, the signal corresponding to another input detected by the case; and a processor configured to:
when the electronic device is not coupled to the case, perform an action associated with the button in response to a detection by the button; and
when the electronic device is coupled to the case, perform the action associated with the button only when the signal is received from the case.

8 . The electronic device of claim 7 , wherein the button comprises a strain gauge configured to generate another signal upon depression of the button.

9 . The electronic device of claim 7 , wherein the action associated with the button is to change a speaker volume setting of the electronic device.

10 . The electronic device of claim 7 , wherein the device communication interface comprises a near-field communication (NFC) coil.

11 . The electronic device of claim 7 , wherein the device communication interface is further configured to receive an identification signal from the case, the identification signal comprising a command to disable the button of the electronic device while the case is coupled to the electronic device.

12 . The electronic device of claim 7 , wherein the device communication interface is further configured to receive an authentication signal from the case, the authentication signal corresponding to an authentication of a user, and the processor is further configured to unlock a feature of the electronic device in response to the authentication signal.

13 . The electronic device of claim 7 , wherein the processor is further configured to perform the action associated with the button only when the signal is received from the case while the button detects the input.

14 . An electronic device for coupling to a case, the electronic device comprising:
multiple buttons configured to detect inputs; a device communication interface configured to receive signals from the case, the signals corresponding to other inputs detected by the case; and a processor configured to, when the electronic device is coupled to the case:
perform a first action associated with a corresponding one of the multiple buttons when a first signal is received from the case, the first signal being generated in response to a first input at a first sensor of the case that overlaps the corresponding one of the multiple buttons; and
perform a second action that is not associated with any of the multiple buttons when a second signal is received from the case, the second signal being generated in response to an input at a second sensor of the case that does not overlap any of the multiple buttons.

15 . The electronic device of claim 14 , wherein each of the multiple buttons comprises a strain gauge configured to generate another signal upon depression of the corresponding one of the multiple buttons.

16 . The electronic device of claim 14 , wherein:
the first action associated with a first one of the multiple buttons is to increase a speaker volume setting of the electronic device; and the second action associated with a second one of the multiple buttons is to decrease the speaker volume setting of the electronic device.

17 . The electronic device of claim 14 , wherein the device communication interface comprises a near-field communication (NFC) coil.

18 . The electronic device of claim 14 , wherein the device communication interface is further configured to receive an identification signal from the case, the identification signal comprising a command to disable the multiple buttons of the electronic device while the case is coupled to the electronic device.

19 . The electronic device of claim 14 , wherein the second signal corresponds to an authentication of a user, and the second action is to unlock a feature of the electronic device.

20 . The electronic device of claim 14 , wherein the processor is further configured to, when the electronic device is coupled to the case, disable the multiple buttons of the electronic device.
