Heres my rough sketch design of how my 100-storey lift interface would be.
The picture pretty much explains how it works, but to add in a few pointers.
This lift might not be user-friendly for disabled people but i think .. all products has its ” good ” and ” bad ” i think this design would be great mainly because of its high-tech touch screen interface. ( and we dont see 100 storey buildings everywhere , so someting like that would be of good use to it)
ALSO , each time a button is pressed from the MAIN MENU there would be a sound playing perheps a ” Bling” sound and when a storey is selected , a higher pitched ” bling” would play , that is to confirm users that they have pressed a button(since this is touch screen , u cant feel if you have pressed anything sound would be a great help)
