A trackpad apparatus comprising: a capacitive touch-sensing pattern disposed on a top surface of the trackpad apparatus; a capacitive pressure-sensing pattern disposed below the capacitive touch-sensing pattern; an insulating layer disposed between the capacitive touch-sensing pattern and the capacitive pressure-sensing pattern; a compressible membrane disposed below the capacitive pressure-sensing pattern; and at least one controller, wherein: the at least one controller and the capacitive touch-sensing pattern are collectively configured to detect location-specific reductions in charge coupling in the capacitive touch-sensing pattern resulting from charge being shunted out of the capacitive touch-sensing pattern by one or more electrically conductive objects being placed in contact with the top surface of the trackpad apparatus; and the at least one controller, the capacitive pressure-sensing pattern and the compressible membrane are collectively configured to detect location-specific changes in charge coupling in the capacitive pressure-sensing pattern resulting from pressure being applied to the top surface of the trackpad apparatus, wherein the location-specific changes in charge coupling in the capacitive pressure-sensing pattern are due at least in part to displacement of the compressible membrane. a capacitive touch-sensing pattern disposed on a top surface of the trackpad apparatus; a capacitive pressure-sensing pattern disposed below the capacitive touch-sensing pattern; an insulating layer disposed between the capacitive touch-sensing pattern and the capacitive pressure-sensing pattern; a compressible membrane disposed below the capacitive pressure-sensing pattern; and at least one controller, wherein: the at least one controller and the capacitive touch-sensing pattern are collectively configured to detect location-specific reductions in charge coupling in the capacitive touch-sensing pattern resulting from charge being shunted out of the capacitive touch-sensing pattern by one or more electrically conductive objects being placed in contact with the top surface of the trackpad apparatus; and the at least one controller, the capacitive pressure-sensing pattern and the compressible membrane are collectively configured to detect location-specific changes in charge coupling in the capacitive pressure-sensing pattern resulting from pressure being applied to the top surface of the trackpad apparatus, wherein the location-specific changes in charge coupling in the capacitive pressure-sensing pattern are due at least in part to displacement of the compressible membrane. the at least one controller and the capacitive touch-sensing pattern are collectively configured to detect location-specific reductions in charge coupling in the capacitive touch-sensing pattern resulting from charge being shunted out of the capacitive touch-sensing pattern by one or more electrically conductive objects being placed in contact with the top surface of the trackpad apparatus; and the at least one controller, the capacitive pressure-sensing pattern and the compressible membrane are collectively configured to detect location-specific changes in charge coupling in the capacitive pressure-sensing pattern resulting from pressure being applied to the top surface of the trackpad apparatus, wherein the location-specific changes in charge coupling in the capacitive pressure-sensing pattern are due at least in part to displacement of the compressible membrane.
