Abstract

A method and a system are provided for controlling a controller without physically touching the controller. A hand or other object interacts with a field surrounding the controller, altering the field. A change in characteristic of the altered field causes a corresponding movement of the controller that, in turn, corresponds to an amount of change in a parameter of a target device being controlled by the controller. The parameter of the target device is controlled by the controller while a user has no physical contact with the controller.

Claims

1. A method, comprising:

generating a field proximate a remote controller, wherein the remote controller includes a housing having a curved support surface;

altering the field in the absence of contact with the controller;

determining a change in characteristic of the altered field; and

using a motive device to move a weight within the housing along a linear track, in response to the change, to cause the curved support surface to roll on a surface supporting the remote controller.

2. The method of claim 1, wherein the altering comprises:

imposing an object into the field.

3. The method of claim 2, wherein the step of imposing comprises:

placing a user'"'"'s hand in the vicinity of the controller in a defined relationship with respect to the structural configuration of the controller.

4. The method of claim 2, further comprising:

controlling at least one parameter of an electrical device in response to the rolling of the curved support surface of the remote controller on the surface supporting the remote controller.

5. The method of claim 4, wherein the electrical device comprises an audio system and the controlled parameter is volume.

6. The method of claim 1, wherein the weight is moved within the housing along the linear track by an amount related to a change in magnitude of a component of the field.

7. The method of claim 1, wherein generating the field comprises generating first and second non-overlapping fields;

wherein altering the field comprises selectively altering one or the other of the first and second fields; and

wherein using the motive device to move the weight along the linear track in response to the change comprises;

moving the weight along the linear track, responsive to altering the first field, to cause the curved support surface to roll on the surface supporting the remote controller in a first direction; and

moving the weight along the linear track, responsive to altering the second field, to cause the curved support surface to roll on the surface supporting the remote controller in a second direction that is different than the first direction.

8. The method of claim 1, wherein the field comprises a capacitive field.

9. The method of claim 1, wherein the field comprises a near field communication (NFC) field.

10. An apparatus, comprising:

a remote controller for remotely controlling a target electrical device, the remote controller embodied in a housing having a predefined structural configuration, the remote controller responsive to a spatial orientation of the housing to adjust a parameter of the target electrical device, the housing further comprising;

a processor;

a field sensor having an output coupled to an input of the processor; and

a motive device mechanically coupled to the housing structure and electrically coupled to an output of the processor for moving a weight within the housing along a linear track to adjust the spatial orientation of the housing;

wherein the processor output is generated in accordance with the input received from the field sensor.

11. The apparatus of claim 10, wherein the housing further comprises a field generator configured to generate a field proximate and external to the housing.

12. The apparatus of claim 11, wherein the output of the field sensor is responsive to a change in the generated field resulting from intervention of an object within range of the field.

13. The apparatus of claim 12, wherein the object is a user'"'"'s hand positioned in the vicinity of the controller in a defined relationship with respect to the structural configuration of the housing.

14. The apparatus of claim 13, wherein the field generator comprises a near field communication (NFC) generator and the field sensor is responsive to an NFC device held by the user'"'"'s hand.

15. The apparatus of claim 13, wherein the field sensor comprises a capacitive field sensor.

16. The apparatus of claim 11, wherein the motive device comprises a motor and

the motive device is responsive to the processor output to move the weight within the housing along the linear track to cause the housing to pivot about an axis by an amount related to a change in magnitude of a component of the field.

17. The apparatus of claim 16, wherein the motor is configured to move the weight from a first position along the linear track to one of a plurality of different second positions along the linear track, and wherein the different second positions correspond to different values of the parameter.

18. The apparatus of claim 16, wherein the weight comprises a battery electrically coupled to the remote controller.

19. The apparatus of claim 16, wherein

the field sensor comprises first and second field sensors for selectively sensing, respectively, first and second non-overlapping fields;
