Abstract
A signalling apparatus comprising: a non-light-emitting element arranged to transmit and/or reflect light from a light-emitting element, the non-light-emitting element having a variable transmission and/or reflectance respectively, and the non-light-emitting element being separate from the light-emitting element; and a controller configured to control the transmission and/or reflectance of the non-light-emitting element in order to temporally modulate the light and to thereby embed data into the light in a manner imperceptible to human vision; wherein the non-light-emitting element is arranged to transmit and/or reflect the light towards a detecting apparatus housed in a unit separate from the light-emitting element and non-light-emitting element, in order for the embedded data to be detected by the detecting apparatus.
