Abstract: A lighting device (31) is configured to determine a group of service-providing devices (41-44) and determine a schedule for the service-providing devices in the group. The group (101) comprises at least two service-providing devices capable of performing a similar or a same lighting service. The schedule indicates for each service-providing device of the group in which time period the service-providing device is able to receive messages such that at least one device of the determined group of service-providing devices is able to receive messages. The lighting device is configured to transmit the schedule to the service-providing devices.

Abstract: A controller handles control events in a system of networked home devices by: receiving a signal indicative of a control event, which is an actuation of a user input device; and in response, determining whether to perform a control function associated with a networked home device, that determination being made in dependence on a state of interaction between that device and a physical environment in which it is located at a time of the control event. If the control function is performed in response to the control event, it causes the networked home device to perform an action that changes the state of interaction between that device and the physical environment in which it is located. Otherwise, the controller causes another control function associated with a different networked home device of the system to be performed in response to the control event instead.

Abstract: The present invention relates to an improved method of controlling interaction between network-enabled devices. In a network comprising multiple control devices, the selection of a control device can enable the mitigation of privacy risks and security risks and can further avoid frequent communications between network-enabled devices and an internet-based service (which increase power usage) as well as prevent devices becoming uncontrollable (based on failure of the network-enabled devices to connect to an internet-based service for control). The method comprises the steps of a user selecting an interaction schedule (102) and selection of a control device (104) as well as configuration of devices (106), based on said interaction scenario and said control scenario.

Abstract: A spatial relationship is determined between a first image of a first region of a physical space, and a second image of a second region of that space; and the first and second images are thereby stitched together into a composite image comprising first and second areas derived from the first and second images respectively. Further, there is detected an embedded signal having been embedded in light illuminating at least part of the first region of the physical space upon capture of the first image, the embedded signal conveying metadata relating to at least part of the physical space. An effect applied to at least part of the first area of the composite image based on the detected metadata; and also, based on the detected metadata and on the determined spatial relationship between the first and second images, the effect is applied to at least part of the second area of the composite image that extends beyond the first area.

Abstract: A controller handles control events in a system of networked home devices by: receiving a signal indicative of a control event, which is an actuation of a user input device; and in response, determining whether to perform a control function associated with networked home device, that determination being made in dependence on a state of interaction between that device and a physical environment in which it is located at a time of the control event. If the control function is performed in response to the control event, it causes the networked home device to perform an action that changes the state of interaction between that device and the physical environment in which it is located. Otherwise, the controller causes another control function associated with a different networked home device of the system to be performed in response to the control event instead.

Abstract: A user can control a plurality of lighting devices by positioning them in a configuration (e.g. a circular configuration). Through receiving the positions of the lighting devices a shape of the configuration can be determined. From a set of light scenes, each light scene associated with a shape, a light scene can be selected matching the shape of the configuration. The plurality of lighting devices are then controlled based on the selected light scene. This allows a user to select, for example, a romantic light scene by placing the lighting devices in a heart shape symbol.
