7. A device for detecting non-contact gestures, comprising:
a memory having processor-executable instructions stored thereon; and
a processor configured to execute the processor-executable instructions to cause the device to perform:
detecting a first capacitive response corresponding to an object hovering in a three-dimensional (3D) space above the device at a first time instance;
detecting a change from the first capacitive response to a second capacitive response at a second time instance, wherein the change from the first capacitive response to the second capacitive response corresponds to a non-contact gesture performed by a user in the 3D space above the device; and
determining based on the change from the first capacitive response to the second capacitive response, a type of the non-contact gesture performed by the user;
wherein the non-contact gesture performed by the user corresponds to a crush gesture;
wherein the change from the first capacitive response to the second capacitive response corresponds to an amplitude of the second capacitive response being greater than an amplitude of the first capacitive response; and
wherein the determination that the crush gesture was performed by the user is in response to the amplitude of the second capacitive response being greater than the amplitude of the first capacitive response and further in response to a width of the second capacitive response being greater than a width of the first capacitive response.
