The method 600 comprises: obtaining 602 positions of the plurality of lighting devices 120, 122, 124 in the physical space 160, obtaining 604 a position of a user 130, receiving 606 a first user input from the user 130 indicative of a first direction originating from the position of the user 130, selecting 608 a first lighting device of the plurality of lighting devices 120, 122, 124 that is located in the first direction relative to the position of the user 130, providing 610 a notification to the user 130 that the first lighting device has been selected, receiving 612 a second user input from the user 130 indicative of a second direction originating from the position of the user 130, mapping 614 the second direction onto the selected first lighting device such that it originates from the position of the selected first lighting device, and selecting 616 a second lighting device of the plurality of lighting devices 120, 122, 124 that is located in the mapped second direction relative to the position of the selected first lighting device. ## Claims ### Claim 1 A method of correcting a selection of a lighting device from a plurality of lighting devices in a physical space, the method comprising: obtaining positions of the plurality of lighting devices in the physical space, obtaining a position of a user, receiving a first user input from the user indicative of a first direction originating from the position of the user, selecting a first lighting device of the plurality of lighting devices that is located in the first direction relative to the position of the user, providing a notification to the user that the first lighting device has been selected, receiving a second user input from the user indicative of a second direction originating from the position of the user, mapping the second direction onto the selected first lighting device such that it originates from the position of the selected first lighting device, and selecting a second lighting device of the plurality of lighting devices that is located in the mapped second direction relative to the position of the selected first lighting device, and deselecting the first lighting device to correct the selection of the first lighting device. ### Claim 2 (depends on 1) The method of claim 1, wherein the second user input is further indicative of a distance, and wherein the step of selecting the second lighting device is further based on the distance. ### Claim 3 (depends on 1) The method of claim 1, wherein the step of providing a notification to the user comprises changing the light output of the first lighting device. ### Claim 4 (depends on 1) The method of claim 1, further comprising: providing a second notification to the user that the second lighting device has been selected. ### Claim 5 (depends on 1) The method of claim 1, further comprising: receiving a control command from the user, controlling or configuring the second lighting device based on the control command. ### Claim 6 (depends on 1) The method of claim 1, wherein the first and/or the second user input is a voice input. ### Claim 7 (depends on 1) The method of claim 1, wherein the first and/or the second user input is a gesture input. ### Claim 8 (depends on 7) The method of claim 7, wherein the step of receiving the first user input and/or the step of receiving the second user input further comprises: capturing one or more images of the user, analyzing the one or more images, and retrieving the gesture input from the one or more images. ### Claim 9 (depends on 7) The method of claim 7, wherein the step of receiving the first user input and/or the step of receiving the second user input further comprises: detecting, by a motion sensor comprised in a portable user device, a movement of the portable user device, and retrieving the gesture input from the movement of the portable user device. ### Claim 10 (depends on 9) The method of claim 9, wherein the second user input is a flicking movement of the portable user device. ### Claim 11 (depends on 1) A computer program product for a computing device, the computer program product comprising computer program code to perform the method of claim 1 when the computer program product is run on a processing unit of the computing device. ### Claim 12 A system for correcting a selection of a lighting device from a plurality of lighting devices in a physical space, the system comprising: a receiver configured to obtain a position of a user, a user interface configured to receive a first user input from the user indicative of a first direction originating from the position of the user, and to receive a second user input from the user indicative of a second direction originating from the position of the user, a processor configured to: obtain positions of the plurality of lighting devices in the physical space, select a first lighting device of the plurality of lighting devices that is located in the first direction relative to the position of the user, and provide a notification to the user that the first lighting device has been selected, wherein the processor is further configured to: map the second direction onto the selected first lighting device such that it originates from the position of the selected first lighting device, and select a second lighting device of the plurality of lighting devices that is located in the mapped second direction relative to the position of the selected first lighting device, and deselect the first lighting device to correct the selection of the first lighting device.
