Abstract

A communication system is provided that allows a user to exchange a stream of data with a user computer device via a capacitive touchscreen of the device. The communication system includes a user'"'"'s data input device having a capacitive user interface and a user computer device having a capacitive touchscreen. When the capacitive user interface of the data input device and the capacitive touchscreen of the user computer device are in sufficient to proximity to each other, an inter-device capacitance is created over which exchanging a stream of data may be exchanged between the data input device and the user computer device.

7. The method of claim 6, wherein reconfiguring comprises determining a quantity of intersecting points of the rows and columns of the touchscreen'"'"'s electrode grid grouped together to emulate one of a single conductor or a plurality of conductors based on one or more of a desired data rate and a quantity of data to be exchanged.

8. The method of claim 1, wherein the exchange of one or more streams of data over the inter-device capacitance is enabled by one or more of a temperature authentication between the user computer device and the external device, a manual command, a context-type detection, and an expiration of a timer.

9. A user computer device comprising

a capacitive touchscreen;
