Methods, apparatus, and processor-readable storage media for providing positional information via use of distributed sensor arrays are provided herein. An example computer-implemented method includes generating and outputting one or more signals via at least one user identification device associated with a user; processing one or more signals output by at least one of multiple emitting sensors distributed in an array within a given indoor environment, wherein the signals output by the at least one emitting sensor are output in response to the signals output via the at least one user identification device, and wherein a least a portion of the multiple emitting sensors comprises infrared sensors; generating a message based on the processing of the signals output by the at least one emitting sensor, wherein the message pertains to positional information with respect to the given indoor environment; and outputting the generated message.
