Abstract
A scanning capability for capacitive touch screen devices is disclosed. Images, such as text, barcodes, or the like are printed on printed objects, such as business cards, information cards, and the like using electrically conductive ink that has had electrical properties imparted thereon such that, when the printed object comes in contact with the touch screen of a capacitive touch screen device, the imparted electrical properties are sufficient to cause variances in capacitance to the touch screen that are detectable by the device. Using these detected touches, the scanning system analyzes any patterns created by the detected touches to determine information represented by those patterns and corresponding to the information represented by the images printed on the printed object.
Claims25
A method comprising:
- substantially simultaneously receiving, by a device comprising a capacitive touch screen, a plurality of locations in response to at least one contact of an object on the capacitive touch screen, the capacitive touch screen comprising a touch panel and each of the plurality of locations corresponding with a position on the capacitive touch screen on the touch panel, each position corresponding with a contact between the capacitive touch screen and electrically conductive ink on the object;
- identifying at least one image based at least in part on the plurality of locations;
- and
- generating representative information based at least in part on the at least one Image.
A method comprising:
- receiving, by a device comprising a capacitive touch screen, a plurality of locations in response to at least one contact of an object on the capacitive touch screen, the capacitive touch screen comprising a touch panel and each of the plurality of locations corresponding with a position on the capacitive touch screen on the touch panel, each position corresponding with a contact between the capacitive touch screen and electrically conductive ink on the object;
- determining at least one pattern based at least in part on the plurality of locations;
- and
- generating representative information based at least in part on the at least one pattern.
A non-transitory computer-readable medium comprising program code, comprising:
- program code for substantially simultaneously receiving a plurality of locations in response to at least one contact of an object on a capacitive touch screen, the capacitive touch screen comprising a touch panel and each of the plurality of locations corresponding with a position on the capacitive touch screen on the touch panel, each position corresponding with a contact between the capacitive touch screen and electrically conductive ink on the object;
- program code for identifying at least one image based at least in part on the plurality of locations, the at least one image corresponding to a portion of the object comprising electrically conductive ink;
- and
- program code for generating representative information based at least in part on the at least one image.
A system comprising:
- a capacitive touch screen;
- and
- a processor in communication with the capacitive touch screen, the processor configured to:
- substantially simultaneously receive a plurality of locations in response to at least one contact of an object on the capacitive touch screen, the capacitive touch screen comprising a touch panel and each of the plurality of locations corresponding with a position on the capacitive touch screen on the touch panel, each position corresponding with a contact between the capacitive touch screen and electrically conductive ink on the object;
- identify at least one image based at least in part on the plurality of locations, the at least one image corresponding to a portion of the object comprising electrically conductive ink;
- and generate representative information based at least in part on the at least one Image.
A device comprising:
- a non-conductive substrate having a first side and a second side opposite the first side;
- an electrically conductive ink, the electrically conductive ink applied to a first portion of the first side of the non-conductive substrate;
- a conducting pad, the conducting pad connected to a second portion of the second side of the non-conductive substrate, the conducting pad configured to physically receive a contact from a finger;
- a conducting trace disposed in the non-conductive substrate, the conducting trace coupling the electrically conductive ink and the conducting pad;
- and
- wherein at least a portion of the electrically conductive ink is configured to be electrically charged when the finger physically contacts the conducting pad.
