Using magnetism to move a physical object proximate a base
First Claim
1. An apparatus, comprising:
- a base comprising a support surface;
a first electromagnet disposed in the base and configured to generate a first magnetic field at the support surface, wherein the first electromagnet comprises;
a first coil formed from a first electrically conductive wire, wherein the first coil forms a first loop from a viewpoint perpendicular to the support surface, wherein the first electromagnet has only the first coil, anda voltage generator coupled to both ends of the first wire;
a controller disposed in the base and configured to control the first magnetic field generated by the first electromagnet according to a predefined gameplay motion pattern configured to induce an entertainment object proximate to the support surface to perform a desired action causing spatial separation of the entertainment object relative to the support surface; and
a second electromagnet configured to generate a second magnetic field at the support surface according to the predefined gameplay motion pattern, wherein the second electromagnet has only a single second coil formed from a second electrically conductive wire, wherein the second coil forms a second loop from the viewpoint perpendicular to the support surface, and wherein the base comprises at most two coils;
wherein the first coil is disposed a first distance from the support surface, and the second coil is disposed a second distance from the support surface, wherein the first coil overlaps the second coil relative to the viewpoint perpendicular to the support surface.

Abstract
In an interactive environment, a user action may dictate what type of action a base device performs using an entertainment object. In one embodiment, the base device includes a controllable electromagnet that uses magnetism to move one or more permanent magnetics mounted in or on the entertainment object. For example, the entertainment object may be a doll or character that jumps, vibrates, slides, or sways in response to a changing magnetic field generated by the electromagnet. Moreover, the user may wear headphones that determine the location of the base device (and the toy) relative to the user. Using this location, the headphones can output 3D positional audio that the user perceives as originating from the location of the entertainment object on the base device. The 3D positional audio can be outputted synchronously with the action performed by the entertainment object to further immerse the user in the interactive environment.
