Computing device case

A system comprising:

• an electronic device comprising:
• a device button;
• and
• sensors coupled to the device button, the sensors configured to identify a first input type using a first sensor, a second input type using a second sensor, and a third input type using a third sensor;
• and
• a device interface comprising a button body configured to cover the device button, the button body permitting user inputs of the first input type, the second input type, and the third input type to be transferred to the device button through the button body.

A system comprising:

• an electronic device comprising a device button coupled to a collapsible switch, a force sensor, and a capacitance sensor;
• and
• a case comprising:
• a frame;
• and
• a button disposed within the frame, the button being operable to transfer a force to actuate the collapsible switch, transfer the force to generate a force signal via the force sensor, and to transfer electric charge to generate a capacitance signal via the capacitance sensor.
