The system performs operations that include identifying a message for display on a touchscreen display of a destination entry system of an elevator. The message includes a selection button for display on the touchscreen display. The at least one selection button is displayed at a first location on the touchscreen display. The at least one selection button is displayed at a different location on the touchscreen display once a rearrangement criterion is satisfied. ## Claims ### Claim 1 A system configured to dynamically assign selection buttons on touchscreen displays, the system comprising: a processor; and a memory comprising computer-executable instructions that, when executed by the processor, cause the processor to perform operations, the operations comprising: identifying a message for display on a touchscreen display of a destination entry system of an elevator, the message comprising at least one selection button for display on the touchscreen display; displaying the at least one selection button at a first location on the touchscreen display; and displaying the at least one selection button at a different location on the touchscreen display once a rearrangement criterion is satisfied, wherein the rearrangement criterion includes a frequency of usage of the at least one selection button, and the different location can be any location on the touchscreen display. ### Claim 2 (depends on 1) The system of claim 1, wherein the destination entry system of an elevator determines whether the rearrangement criterion is satisfied. ### Claim 3 (depends on 1) The system of claim 1, wherein a controller of the destination entry system of an elevator determines whether the rearrangement criterion is satisfied. ### Claim 4 (depends on 1) The system of claim 1, wherein it is determined on a periodic basis whether the rearrangement criterion is satisfied. ### Claim 5 (depends on 1) The system of claim 1, wherein the rearrangement criterion is satisfied based at least in part on the at least one selection button being selected a threshold number of times at the first location. ### Claim 6 (depends on 1) The system of claim 1, wherein the rearrangement criterion is satisfied based at least in part on an estimated number of times that the at least one selection button is selected at the first location being over a threshold number. ### Claim 7 (depends on 1) The system of claim 1, wherein the destination entry system is one of a free-standing device entry terminal (DET) and a wall mounted hallway fixture. ### Claim 8 (depends on 1) The system of claim 1, wherein the destination entry system is an elevator car operating panel (COP) inside an elevator car. ### Claim 9 (depends on 1) The system of claim 1, wherein the at least one selection button comprises a graphic that indicates a floor of a building. ### Claim 10 (depends on 1) The system of claim 1, wherein the message further comprises a second selection button that is displayed at a second location on the touchscreen display prior to the rearrangement criterion being satisfied and at a third location on the touchscreen display subsequent to the rearrangement criterion being satisfied. ### Claim 11 A method of dynamically assigning selection buttons on touchscreen displays, the method comprising: identifying a message for display on a touchscreen display of a destination entry system of an elevator, the message comprising at least one selection button for display on the touchscreen display; displaying the at least one selection button at a first location on the touchscreen display; and displaying the at least one selection button at a different location on the touchscreen display once a rearrangement criterion is satisfied, wherein the rearrangement criterion includes a frequency of usage of the at least one selection button, and the different location can be any location on the touchscreen display. ### Claim 12 (depends on 11) The method of claim 11, wherein the destination entry system of an elevator determines whether the rearrangement criterion is satisfied. ### Claim 13 (depends on 11) The method of claim 11, wherein a controller of the destination entry system of an elevator determines whether the rearrangement criterion is satisfied. ### Claim 14 (depends on 11) The method of claim 11, wherein it is determined on a periodic basis whether the rearrangement criterion is satisfied. ### Claim 15 (depends on 11) The method of claim 11, wherein the rearrangement criterion is satisfied based at least in part on the at least one selection button being selected a threshold number of times at the first location. ### Claim 16 (depends on 11) The method of claim 11, wherein the rearrangement criterion is satisfied based at least in part on an estimated number of times that the at least one selection button is selected at the first location being over a threshold number. ### Claim 17 (depends on 11) The method of claim 11, wherein the destination entry system is one of a free-standing device entry terminal (DET) and a wall mounted hallway fixture. ### Claim 18 (depends on 11) The method of claim 11, wherein the destination entry system is an elevator car operating panel (COP) inside an elevator car. ### Claim 19 (depends on 11) The method of claim 11, wherein the at least one selection button comprises a graphic that indicates a floor of a building. ### Claim 20 (depends on 11) The method of claim 11, wherein the message further comprises a second selection button that is displayed at a second location on the touchscreen display prior to the rearrangement criterion being satisfied and at a third location on the touchscreen display subsequent to the rearrangement criterion being satisfied.
