Abstract

The present invention relates to a method comprising providing one or more information carrier(s) with a dielectric and/or conductive pattern and a detection device having a capacitive touch screen and inducing an interaction between the information carrier and the touch screen, wherein the interaction is based on a difference in the dielectric coefficient and/or the conductivity of the pattern and generates a touch signal and wherein the interaction is induced by relative motion between the information carrier and the touch screen. The invention further relates to a system comprising an information carrier comprising a dielectric and/or conductive pattern which encodes information and a detection device having a touch screen; the detection device is able to decode the information upon interaction between the information carrier and the touch screen, wherein the interaction is caused by a difference in the dielectric coefficient and/or the conductivity of the pattern.

Claims

1. A method with the following steps:

a. providing one or more information carrier(s) with one or both of a dielectric pattern defining areas or regions having different dielectric coefficients and a conductive pattern defining areas or regions having different conductivities; and

b. causing a touch signal to be generated at a touch screen of a detection device in response to an interaction between the information carrier and the touch screen, wherein the interaction is based on one or both of a difference in the dielectric coefficients of the dielectric pattern and a difference in the conductivities of the conductive pattern.

2. A method according to claim 1, wherein the touch signal is generated based on an interaction that comprises relative motion between the information carrier and touch screen and includes manipulating gestures, deictic gestures, and/or symbolic gestures, emulating gestures and/or imitating gestures.

3. A method according to claim 2, wherein the relative motion includes a slide-through-gesture, a slide-in-gesture, a turnkey-gesture, putting, slapping, crumpling, rubbing and/or a combination of these.

4. A method according to claim 1, wherein causing the touch signal to be generated further causes the detection device to return feedback by haptic perception, tactile perception, auditory perception and/or visual perception.

5. A method according to claim 1 wherein the touch signal is generated by an at least partial direct contact between the information carrier and the touch screen.

6. A method according to claim 1 wherein causing the touch signal to be generated further causes the detection device to vibrate during and/or after the interaction.

7. A method according to claim 1 wherein causing the touch signal to be generated further causes the detection device to give a tactile, acoustic and/or visual signal before, during and/or after the interaction.

8. A method according to claim 1 wherein one or more touch signals are caused to be generated by multiple interactions between the information carrier and detection device, each single interaction occurring for less than 1 minute.

9. A method according to claim 1 wherein causing the touch signal to be generated occurs in response to an interaction between the information carrier and the touch screen and one or more of the following interactions:

a user interacting with the information carrier, and

a user interacting with the touch screen.

10. A method according to claim 1 wherein causing the touch signal to be generated occurs while the information carrier is stationary and the touch screen is moving, or while the touch screen is stationary and the information carrier is moving, or while the touch screen and the information carrier are both moving.

11. A method according to claim 1 wherein causing the touch signal to be generated occurs in response to a combination of (i) an interaction between the information carrier and the touch screen and (ii) one or more users having two or more connections to the information carrier, each of said connections causing an interaction between the one or more users and the information carrier.

12. A method according to claim 1 wherein causing the touch signal to be generated occurs in response to a combination of (i) an interaction between the information carrier and the touch screen and (ii) for two or more users, an interaction between each user and one or both of the information carrier and the touch screen.

13. A method according to claim 1 wherein causing the touch signal to generated occurs when the detection device and/or information carrier is aligned in a vertical or horizontal orientation.

14. A method according to claim 1 wherein the touch signal indicates to the detection device that the information carrier is interacting with the touch screen.

15. An information carrier carrying encoded information, the information carrier comprising one or both of a dielectric pattern defining areas or regions having different dielectric coefficients and a conductive pattern defining areas or regions having different conductivities,

wherein the information carrier is adapted to interact with a detection device such that the detection device decodes the encoded information upon said interaction, the decoding being based on one or both of a difference in the dielectric coefficients of the dielectric pattern and a difference in the conductivities of the conductive pattern.

16. An information carrier according to claim 15, further comprising:

a substrate of a first material;

a second material applied to regions of a surface of the substrate, thereby forming one or both of the dielectric pattern and conductive pattern.

17. An information carrier according to claim 16, wherein the surface of the substrate includes one or more recesses, said recesses being filled with the second material.

18. An information carrier according to claim 16, further comprising a laminate at least partially covering or coating the second material.

19. An information carrier according to claim 16, wherein the substrate is one of a playing card, business card, credit card, debit card, stamp, signature, postcard, ticket, admission card, member card, certificate, bill of delivery, bill of sale, abstract, instruction leaflet, voucher, cup, glass, consumer packaged good, consumable and pre-product.

20. A system comprising:

an information carrier according to claim 15; and

a detection device a touch screen, wherein the information carrier is adapted to interact with the touch screen of the detection device, said interaction generating a touch signal at the detection device.
