According to an embodiment the controller 280 may determine that passenger 220 requires service when the mobile device 230 is within a predetermined distance of a lobby 290 for the elevator 260. For example the passenger 220 may be ten (10) yards from the first lobby 290, which provides sufficient notice to the controller 280 to instruct the elevator 260 to arrive at the first lobby 290. The first controller 280 may transmit instructions to the mobile device 230 to alert the passenger 220 that the elevator 260 includes an accessibility implement 270 and is assigned to service the passenger 220. According to an embodiment the instructions to the mobile device 230 from the controller 280 include navigational directions between a current location of the mobile device 230 and a lobby 290 on the first level 250 for receiving the elevator 260.
According to an embodiment the accessibility implement 270 comprises delayed idling at the first floor 250. Accordingly, the instructions to the elevator 260 include the elevator 260 idling at the first lobby 290 for a first period of time that accounts for a navigational distance on the first level 250 between the current location of the mobile device 230 and the first lobby 290. According to an embodiment the controller 280 may receive accelerometer data from the mobile device 230 during the first period of time and thereby track a location of the mobile device 230. When the accelerometer data indicates the mobile device 230 is diverging from the navigational directions to the first lobby 290, the elevator 260 may be released from effecting the second determination. In addition, at the end of the first period of time, when the elevator 260 fails to detect a presence of the mobile device 230 proximate the first lobby 290, the elevator 260 may be released from effecting the second determination.
In one embodiment the controller 280 may determine that the passenger 280 is visually impaired. In such embodiment, the controller 280 may instruct the mobile device 230 to provide navigational directions as audible instructions. In such embodiment, the controller 280 may identify an elevator 260 that satisfies plural conditions of being equipped with required accessibility implements 270 and being closest to a current location of the passenger. In such embodiment delayed idling by the elevator 260 at the lobby may also be implemented.

According to the above disclosed embodiments a passenger 220 having a mobile device 230 may be registered in controller 280 for a building 210 which may be a hotel, and provided with key credentials by the controller 280, in order to obtain room access control. The key credentials may indicate that the passenger 220 has a disability, for example, as defined under the Americans with Disabilities Act of 1990 (the ADA). The ADA defines a disability as “a physical or mental impairment that substantially limits one or more major life activities, a person who has a history or record of such an impairment, or a person who is perceived by others as having such an impairment” (https://www.ada.gov/).
In one embodiment once the first mobile device 230 is brought on a first level near a beacon 320 associated with a plurality of elevators generally referred to as 330 including the elevator 260, the controller 280 may communicate with the mobile device 230 over the personal area network (PAN) 310, such as Bluetooth, to obtain the key credentials stored in the mobile device 230 for the passenger 220. The controller 280 may communicate with the mobile device 230 over the personal area network 310, for example over Bluetooth, and obtain the data from the controller 280 that the passenger 220 has the disability.
The controller 280 may effect a determination that an ADA compliant elevator will transfer the passenger 220 to a level selected by the passenger 220. The controller 280 may determine that an elevator 260 in an elevator bank is compliant with the ADA. The controller 280 may transmit instructions for the mobile device 230 to publish an alert indicating a location on the first level 250 for a first lobby 290 associated with the elevator 260. The controller 280 may send instruction to the elevator to travel to a first lobby 290 and idle at the first lobby 290 until instructed to travel to a destination level by the passenger. If the passenger 220 is not detected at the second elevator 260 before a threshold period of time, the controller 280 may release the elevator 260 from effecting the determination.
When sending the instruction the controller 280 may monitor a location of the mobile device 230 of the passenger 220 to thereby track a location of the passenger 220. The controller 280 may monitor the location of the mobile device 230 by receiving accelerometer data from the mobile device 230.
Regarding accessibility implements as identified above, according to an embodiment the ADA accessibility implements for the elevator 260 may be one or more of (i) elevator hall and car buttons that are mounted at certain heights (for example but not limited to 42 inches), (ii) call buttons that are a minimum of for example but not limited to 0.75 inches in diameter, (iii) certain illumination levels for buttons, (iv) braille plates next to buttons and at entrance jambs, (v) two-way communication in elevator cabs that deaf/blind users can utilize, (vi) chimes/verbal announcements that indicate level passing and the next arrival level, (vii) a cab large enough to accommodate a wheelchair and for example but not limited to a 360-degree turn, (viii) hall lantern fixtures that are mounted with their centerlines at least for example but not limited to 72 inches from the level, (ix) door protective/reopening devices that will reopen the door without physical contact, (x) emergency controls that are grouped at the bottom of the elevator control panel and have their centerlines for example but not limited to no less than 35-inches above the finish level, and (xi) handrails at specific heights (for example but not limited to 30 inches). The access implements for an ADA compliant elevator are provided at section 407 of the ADA (executed in 1990 and updated in 2010) and section A17.1-2010, Safety Code for Elevators and Escalators, published by the ASME Handbook (American Society of Mechanical Engineers), each of which is incorporated herein by reference in their entirety.
