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.
Claims20
A self-capacitance device comprising:
- (a) a body;
- (b) a capacitance coil disposed within the body;
- and
- (c) at least three contacts disposed on a distal side of the body, wherein the atleast three are in electrical contact with the capacitance coil.
An object identification system for use with a touchscreen device, the system comprising:
- (a) at least two self-capacitance devices, wherein each self-capacitance device comprises:
- (i) a body;
- (ii) a capacitance coil disposed within the body;
- and
- (iii) at least three contacts disposed in a predetermined pattern on adistal side of the body such that the predetermined pattern is unique to the self-capacitance device, wherein the at least three are in electrical contact with the capacitance coil;
- and
- (b) a software application configured to recognize each predetermined pattern of the at least three contacts on each of the at least two self-capacitance devices.
A self-capacitance device comprising:
- (a) a device body;
- (b) an object disposed on a first side of the body.
- (c) a capacitance structure disposed within the body;
- and
- (d) at least three contacts disposed on a second side of the body, wherein the at least three contacts are in electrical contact with the capacitance structure.
