Abstract
Disclosed herein are various embodiments of a self-capacitance device that is configured to be detectable by a known touchscreen without the need for human contact. Such a device has a device body, a capacitance structure disposed within the body, and at least three contacts disposed on one side of the body and electrically coupled to the capacitance structure. Further disclosed herein are systems having at least two such self-capacitance devices and a software application configured to recognize each of the at least two self-capacitance devices.
