摘要： Systems and methods provide technology for wayfinding assistance for visually-impaired passengers, including short-range transmitters distributed within a passenger cabin of an aircraft, a transit vehicle or a vessel, each short-range transmitter located proximate to a respective waypoint in the passenger cabin to transmit a signal identifying the respective waypoint in the passenger cabin, and a client application to, responsive to passing within a range of one of the plurality of short-range transmitters, receive a first transmission from the short-range transmitter and emit one or more of a first audible signal or a first haptic signal, based on the first transmission, as wayfinding assistance to a user of the client device. The technology can also include a mid-range transmitter located proximate to a service area in the passenger cabin, to transmit a signal providing at least one of a status of or a location of the service area.
