Abstract
A method of controlling a light source (105) via a handheld computing device (110) is disclosed. The method comprises receiving an input produced by one or more sensors of the handheld computing device, the input being indicative of a current orientation of the handheld computing device. The method further comprises determining, based at least in part on the input, that the handheld computing device is in a predefined triggering orientation, e.g. in a generally horizontal orientation. In response to so determining, one or more frames of image data are acquired via an image sensor connected to the handheld computing device (110). The method further comprises obtaining an identifier of the light source, e.g. from information encoded into light emitted by the light source (105), having determined that the one or more frames of image data comprise image data representative of the light source (105). The method further comprises transmitting to the light source (105) a command indicative of a desired light setting for the light source (105), which desired light setting may for example have been provided via user input or may be a predefined setting retrieved from memory. A handheld comp…
