Configuration of user interface

1. A system comprising:

a first device associated with a user and having a user interface for presenting a set of controls;

a second device associated with the user and having a display for displaying content to the user; and

a server connected to the first device and to the second device, wherein the first and second devices are configured to operate at least in part under control of the server, and,

wherein the user interface of the first device is configured to be associated with content on the display of the second device, and the set of controls presented in the user interface of the first device is different in dependence on:

(i) a state of content displayed on the second device, wherein:

in a first state of the content displayed on the second device, with the first device being configured to be associated with the content on the display of the second device, a first user interface arrangement with first controls is presented at the user interface of the first device; and

in a second, different state of the content displayed on the second device, with the first device being configured to be associated with the content on the display of the second device, a second user interface arrangement with second, different controls is presented at the user interface of the first device, and

(ii) a context of the user associated with the first device, where the context represents a state of the user, wherein the set of controls presented in the user interface is different in dependence on the context of the user for a given content on the display of the second device,

wherein:

in a first user context of the user, with the first device configured to be associated with the content on the display of the second device, a user interface arrangement with the first controls or the second controls is presented at the user interface of the first device, and

in a second, different, user context of the user, with the first device configured to be associated with the same content on the display of the second device, a third, different, user interface arrangement with third, different, controls is presented at the user interface of the first device.

2. The system according to claim 1 in which the user interface of the first device is configured by the server to a mode of operation to obtain ratings information of the displayed content, indicating the user's ratings of the displayed content.

3. The system according to claim 1 in which the user interface of the first device is configured by the server to a mode of operation to provide a remote control to control the displayed content.

4. The system according to claim 1 in which the user interface of the first device is configured by the server in dependence on sensed information.

5. The system according to claim 1 in which the user interface of the first device is configured by the server in dependence on relative positions of the first device and the second device.

6. The system according to claim 5 in which the user interface of the first device is further configured by the server in dependence on relative locations of the first and second devices.

7. The system according to claim 6 in which the user interface of the first device is further configured by the server based on a specific location of the first device.

8. The system according to claim 5 in which the user interface of the first device is configured by the server dependent on a relative orientation of the first and second devices.

9. The system according to claim 3 in which the remote control is provided by the user interface of the first device in conjunction with a user interface of a third device.

10. The system according to claim 9 in which information is displayed on one of the first, second, and third devices, and inputs are provided at another of the first, second, and third devices, to enable control of the displayed content.

11. The system according to claim 1 in which the content associated with the second device is not displayed.

12. The system according to claim 11 in which the user interface of the first device is additionally configured by the user in dependence on a user interface of a third device.

13. The system according to claim 1 in which the first device is a watch-type device.

14. The system according to claim 1 in which the first device is interactive glasses.

15. The system according to claim 1 in which the first device is used in combination with a third device having a user interface, one of the user interfaces of the first and third devices being used for a display, and one of the user interfaces of the first and third devices being used for an input.

16. The system according to claim 1 in which the user interface of the first device is further configured by the server by customising it in dependence on user preferences.

17. The system according to claim 1 wherein the user interface of the first device is further configured in dependence on a current and predicted context of the user associated with the first device.

18. The system according to claim 1 wherein the user interface of the first device is configured in dependence on a type of the first device.

19. The system according to claim 1 wherein the context is a descriptor which the first device measures or infers from one or more sensors or data stores to further configure the user interface of the first device.

20. A method of controlling a system comprising a first device having a user interface for presenting a set of controls and a second device having a display for displaying content, each of the devices being associated with a user, and a server connected to the first device and to the second device, wherein the first and second devices are configured to operate at least in part under control of the server, the method comprising:

associating the user interface of the first device with the content displayed on the display of the second device;

customizing the user interface of the first device in dependence on:

(i) a state of content displayed on the second device, wherein:

in a first state of the content displayed on the second device, with the first device configured to be associated with the content on the display of the second device, a first user interface arrangement with first controls is presented at the user interface of the first device; and

in a second, different state of the content displayed on the second device, with the first device configured to be associated with the content on the display of the second device, a second user interface arrangement with second, different controls is presented at the user interface of the first device, and

(ii) a context of the user associated with the first device, wherein the context represents a state of the user, wherein the set of controls presented in the user interface is different in dependence on the context of the user for a given content on the display of the second device, wherein:

in a first user context of the user, with the first device being configured to be associated with content on the display of the second device, a user interface arrangement with the first controls or the second controls is presented at the user interface of the first device, and

in a second, different, user context of the user, with the first device being configured to be associated with the same content on the display of the second device, a third, different, user interface arrangement with third, different, controls is presented at the user interface of the first device.
