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 capacitance structure;
- and
- (b) at least three contacts disposed in a predetermined pattern such that the predetermined pattern is unique to the self-capacitance device, wherein the at least three contacts are in electrical contact with the capacitance structure,
- wherein the self-capacitance device is detectable by a touchscreen without human contact as a result of the capacitance structure when the at least three contacts are positioned in contact with the touchscreen, and
- wherein the self-capacitance device is identifiable by the touchscreen by the predetermined pattern.
An object identification system for use with a touchscreen device, the object identification system comprising:
- (a) a self-capacitance device, wherein the self-capacitance device comprises:
- (i) a body;
- (ii) a capacitance structure disposed within the body;
- and
- (iii) at least three contacts disposed in a predetermined pattern on a distal 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 structure;
- and
- (b) a software application configured to recognize each predetermined pattern of the at least three contacts on each of the self-capacitance device,
- wherein the self-capacitance device is detectable by a touchscreen without human contact as a result of the capacitance structure when the at least three contacts are positioned in contact with the touchscreen.
A self-capacitance device comprising:
- (a) a device body;
- (b) a capacitance structure disposed within the device body;
- and
- (c) at least three contacts disposed in a predetermined pattern on a second side of the device body such that the predetermined pattern is unique to the self-capacitance device, wherein the at least three contacts are in electrical contact with the capacitance structure,
- wherein the self-capacitance device is detectable by a touchscreen without human contact as a result of the capacitance structure when the at least three contacts are positioned in contact with the touchscreen, and
- wherein the self-capacitance device is identifiable by the touchscreen by the predetermined pattern.
