Abstract
An invisible light sensing device senses invisible light from a plurality of invisible light emitting objects in which each of the invisible light emitting objects emits invisible light in an identification pattern that is distinct from other identification patterns. An identification pattern is based on one or more apertures through which invisible light is emitted to form the identification pattern. An identification pattern is also based on a plurality of invisible light emitters in which at least a portion of the invisible light emitters are positioned and activated to form the identification pattern.
