Just a general question on the elevator control panel. You have there level 1~8, so the buttons don’t get too high for people on wheelchairs to operate. What if the elevator is for a skyscraper, with 100 levels?
I think that is a general problem. I have seen little girl who lives on 15th floor having to tip-toe to get home. I guess the best solution, really, is to have a touch screen control like that of an ATM machine.
