In another example, if the display screen 208 is located in a lobby then the display screen 208 may display posts 325 and/or advertisements 270 relevant to lobby stores. In another example, if the display screen 208 is located on a spa floor then the display screen 208 may display posts 325 and/or advertisements 270 relevant to the spa. Alternatively, in another embodiment, the controller 206 may also determine where the device 208 is heading (e.g. a destination of the mobile device 208) and display posts 325 regarding the destination. For example, while in the lobby, the controller 206 may determine that the device 208 is heading to the spa and then the display screen 208 in the lobby may display posts 325 and/or advertisements 270 relevant to the spa. In another example, while in the lobby, the controller 206 may determine that the device 208 is heading to the spa and then the display screen 208 in an elevator car may display posts 325 and/or advertisements 270 relevant to the spa as the device 208 heads to the spa.

Embodiments generate a user interface on the device 208 through a community post application 255a, 255b. The community post application 255a may be used for user of the user mobile device 208a to enter posts 325. For example, a resident may report that they will be having a party and to let them know if it gets too loud.

FIGS. 3-4 depict an example user interface 300 on a user mobile device 208a. Referring to FIGS. 3-4 with continued reference to FIGS. 1 and 2, when the user mobile device 208a launches the community post application 255a, an “our community” screen 301 may be presented as shown in FIG. 3. The community post application 255a may display posts 325 entered by various user mobile devices 208a. The source of the posts 325 may be identified by a user name 305. As seen in FIG. 3, the posts 325 may be sorted and the newest post may be seen first. In one embodiment, a user may be able to flag favorite users and have their posts appear first. In one embodiment, a user may be able to block posts from certain users. In another embodiment, the posts 325 may be sorted or filtered by topic tags (ex. social events, building maintenance discussions, etc) or post type (ex. pictures, advertisements, posts by people on the same floor).

In order to enter a post 325, a user can select the “add a post” 303 button, which will prompt the user interface 300 to generate a “new post” section 302 within the “our community” screen 301, as shown in FIG. 4. As seen in FIG. 4, the “new post” section 302 includes a text input section 304 where the new post 325 may be entered. In an embodiment, the post 325 may be manually typed into a text input section 304 by a user of the user mobile device 208a. The text input section 304 is not intended to be limiting as other data input methods may be used, such as, for example drop down menus to display multiple options for data entry. In another embodiment, the post 325 may be entered via a verbal input from a user of the user mobile device 208a. Once a user of the user mobile device 208a has completed entry of their post 325 in the text input section 304, the user may select an “Add Post” button 310 to transmit the post 302 to the controller 206. The controller 206 may then determine which display screen 205 to display the post 325 on. In embodiment, pictures may be included in posts 325. The user may be able to take a picture from the display screen 205 or select an existing picture file from their user mobile device 208-1.

Referring now to FIG. 5, with continued reference to FIGS. 1-4. FIG. 5 shows a flow chart of method 500 of operating a building information conveyance system 200, in accordance with an embodiment of the disclosure. At block 504, one or more posts 325 are received from a first user mobile device 208a-1. The posts may be sent from a social media platform including but not limited to Facebook, twitter, Instagram, LinkedIn, or any other social media platform known to one or skill in the art. The posts 325 may be entered via a verbal input on the first user mobile device 208a-1. At block 506, the controller 206 determines at least one display screen 205 to display the one or more posts 325. The controller 206 may determine to post certain posts 325 to certain display screens 205. For instance, if the post 325 is in relation to one side of a building 202 the controller 206 will display the post 325 on display screen 205 on that one side of the building 202.

At block 508, the one or more posts 205 are displayed on a display screen 205. In an embodiment, the display screen 205 is located in an elevator car 204. In an embodiment, the display screen 205 is interactive and a user may scroll through the posts 325 displayed. For example, the user may user their user mobile device 208a to scroll through the posts 325, the display screen 205 may be a touch screen, or the display screen 205 may have a manual scroll button. In an embodiment, the controller 206 may detect when a third user mobile device 208a-3 is located in the elevator car 204 and filter the one or more posts 325 on the display screen 205 located in the elevator car 204 in response to user data 326 of the third user mobile device 208a-3 located in the elevator car 204. In an embodiment, the user data 326 includes a home location of the third user mobile device 208a-3. For example, the home location may be the floor in the building 202 on which the user of the third user mobile device 208a-3 lives. Advantageously, by filtering the posts 325 based on the user data 326, the user may only view information relevant to that user. Additionally, the posts 325 may also be sorted. In one embodiment, the posts 325 may be sorted in order of the posts 325 are received. In another embodiment, the posts 325 may be sorted in response to the user data 326. For example, based on the user data 326 some posts 325 may be more relevant to a user than other posts 325 and the relevancy may drive the sort. At block 510, the one or more posts 325 are displayed on a second user mobile device 208a-2. The posts 325 may also be filtered and/or sorted on the second user device 208a-5, as described above in relation to the display screen 205.

Further, the method 500 may also include transmitting the posts 325 to a manager device 208b. The manager using the manager device 208b may then review the posts 325 and decide whether a particular post 325 should be removed from being displayed on a display screen 205 and/or user mobile device 208a. The manager may use the manager device 208b to send a remove request to the controller 206 in order to remove a post 325. In an embodiment, the manager may be required to approve all posts 325 prior to the post 325 being displayed. Alternatively, the posts 325 may be limited to a maximum number of posts 325 from a user and/or a frequency of posts 325 form a user. The manager may also use the manager device 208b to send a block request to the controller to block a particular user of a user mobile device 208a from posting, thus the posts 325 from that user will no longer be displayed any display screen 205 and/or any user mobile device 208a. An alert may be transmitted to a user mobile device 208a when they have been blocked and/or a post 325 from the user mobile device 208a has been removed. The alert will indicate the block request or the remove request.
