Abstract: The examples relate to implementations of apparatuses, such as lighting devices, and a system that uses a speech-based user interface to provide speech-based navigation services. The speech-based user interface provides navigation instructions that direct a person to the location of an item within a premises. The person interacts with a speech-based apparatus to receive the navigation instructions as speech-based directions through the premises from a specified location to the item location, or as static navigation instructions enabling the person to navigate from the specified location to the item location. A directional microphone and a controllable speaker receive audio inputs from and output audio outputs to a specified location or subarea of the premises to a person using the speech-based user interface. The audio outputs are directed to the person in the subarea of the premises, and have a higher amplitude within the subarea than outside the subarea of the premises.

Abstract: A lighting system includes luminaires each having a light source for providing illumination in a space and a radio frequency identification (RFID) antenna. An RFID reader is coupled to the RFID antennas in all the luminaires. The RFID reader may transmit at least one RFID intended recipient message from at least one of the antennas and receive a responsive RFID reply message from a recipient device within the space via a plurality of the antennas. The RFID reader may determine a signal attribute of a reply message signal received via each receiving antenna. The determined signal attributes of the reply message signals received via antennas and information about locations of the receiving antennas are processed to estimate a position of the recipient device within the space.
