Abstract: The disclosure relates to the control of a lighting system illuminating a space such as a room. The controller receives signals from a mobile user terminal, including an indication of a user input entered by a user via an on-screen user interface of the mobile user terminal. The controller is also able to determine a position from which the user input was entered by the user. Further, each of a plurality of discrete control policies is associated with a respective positional demarcation within the space in question, where each control policy defines a respective type of response of the illumination to one or more on-screen elements of the lighting-control user interface. Based on this association, the controller selects one of the control policies associated with the determined position. The controller then controls the lighting system to provide the illumination in accordance with the response defined by the selected control policy.

Abstract: An apparatus comprises a controller and an input for receiving a signal from a microphone. The controller processes the signal from the microphone to detect a sound associated with the use of a consumable by a user, and generates an output in response to detecting that sound. For example the consumable may be pre-packaged and the sound may be associated with the packaging. In embodiments the controller controls ambient lighting in response to the sound of a first action (e.g. opening the cap of a container), and controls task lighting in response to the sound of a second action (e.g. dispensing the product from the container). In another embodiment the controller detects a sound indicative of the consumable running out (e.g. the hollow sound of the container being put down on a surface), and in response generates a visible indicator or transmits a signal over a network.
