Abstract
Improved techniques for identifying objects, such as toy objects, are presented herein. In particular, a play system (e.g., game, doll playset, track set, etc.) includes a probed surface for use in obtaining electrical tomography measurements when toy objects are placed on the probed surface. The play system is configured to analyze the electrical tomography measurements to determine an identity of the toy object placed on the probed surface.
Claims20
A method, comprising:
- performing a plurality of electrical tomography measurements for a play surface of a toy;
- and
- analyzing the plurality of electrical tomography measurements to determine an identity of a toy object positioned on the play surface of the toy, wherein the analyzing includes identifying one of:
- a stamp on a bottom of the toy object that indicates the identity of the toy object, wherein the stamp is configured to disrupt the plurality of electrical tomography measurements in a known pattern;
- or
- a metallic stamping of a bottom of the toy object that indicates the identity of the toy object.
One or more non-transitory computer readable storage media encoded with software comprising computer executable instructions that, when executed by a processor, cause the processor to perform operations, comprising:
- performing a plurality of electrical tomography measurements for a play surface of a toy;
- and
- analyzing the plurality of electrical tomography measurements to determine an identity of a toy object positioned on the play surface of the toy, wherein the analyzing includes identifying one of:
- a stamp on a bottom of the toy object that indicates the identity of the toy object, wherein the stamp is configured to disrupt the plurality of electrical tomography measurements in a known pattern;
- or
- a metallic stamping of a bottom of the toy object that indicates the identity of the toy object.
A toy, comprising:
- a play surface;
- a memory;
- and
- at least one processor coupled to the play surface and the memory, wherein the processor is configured to:
- obtain a plurality of electrical tomography measurements from the play surface, and
- analyze the plurality of electrical tomography measurements to determine an identity of a toy object positioned on the play surface, wherein the analyzing includes identifying one of:
- a stamp on a bottom of the toy object that indicates the identity of the toy object, wherein the stamp is configured to disrupt the plurality of electrical tomography measurements in a known pattern;
- or
- a metallic stamping of a bottom of the toy object that indicates the identity of the toy object.
