INPUT DEVICE AND METHOD FOR CAPACITIVE TOUCH SCREEN |
摘要 |
A method, computer program product, and system for generating pattern data in response to placing a primary plane of a capacitive signature label in close physical proximity with a primary plane of a capacitive touch screen to cause a measurable change in capacitance by distorting the touch screen's electrostatic field, the signal is based on a two-dimensional conductive pattern of the capacitive signature label, comparing the generated pattern data with stored pattern data, and performing an action associated with a particular stored pattern data matching the generated pattern data. |

1. A capacitive signature label recognition method comprising:
generating first pattern data in response to placing a primary plane of a capacitive signature label on a primary plane of a capacitive touch screen sufficient to cause a measurable change in capacitance by distorting the touch screen's electrostatic field, wherein the capacitive signature label includes a two-dimensional conductive pattern arranged on a substantially flat surface such that the two-dimensional conductive pattern is neither recessed nor raised relative to the substantially flat surface of the capacitive signature label, and the generated first pattern data being based on the two-dimensional conductive pattern; storing the generated first pattern data in a database; generating second pattern data in response to placing the primary plane of the capacitive signature label on with the primary plane of the capacitive touch screen to cause a measurable change in capacitance by distorting the touch screen's electrostatic field, the generated second pattern data being based on the two-dimensional conductive pattern, the two-dimensional conductive pattern comprising an array of conductive elements at least some of which are passive elements and at least some of which are active elements; identifying the capacitive signature label, by the touch screen, based on a comparison between the generated second pattern data and the generated first pattern data stored in the database; receiving electronic data from the identified capacitive signature label in the form of a binary code, wherein receiving the electronic data comprises detecting a variation in the charge of the active elements while no variation in the charge of the passive elements is detected; and loading a user profile based on the identified capacitive signature label of the second pattern data. |
