Localight-a battery-free passive localization system using visible light
Most existing indoor localization systems are battery-powered and use the changes in Radio
Frequency (RF) signals to localize objects. In this paper, we present LocaLight: a battery-
free indoor localization system that localizes objects using visible light by tracking the
shadow they cast. By sensing a drop in the intensity of ambient light caused by the presence
of a shadow, LocaLight localizes the object. Since the position of the shadow can be
predicted, it is possible to localize the object in a sensitive area by carefully positioning the …
