  Question: What's the decision of buttons size and scale design when discussing the design of the remote control?
  Answer:
output: It may require more than three millimetres with three buttons, and since there are not as many buttons, each button should be fully functional so that the basic requirements of the user can be met and the operation can be simple, or at least not too complicated, while they enjoy the function.
