Hands-free Elevator Buttons
For those that moved out and took a place on the higher floors of an apartment, then you have suffered from not being able to reach the elevator buttons. With both hands occupied, not being able to touch the correct button is annoying. In the end, you either have to put down your heavy boxes, which could potentially break your back, or ask someone for help to press the correct floor. However, that is a problem forever solved.
Hopefully, every elevator worldwide can adopt this design to allow passengers to press their floor’s button with their feet. A common “feat” like this can also lower the chance of contracting germs.
