  Question: Why did the group give up the idea of positioning symmetrical buttons on both the left and right side?
  Answer:
output: Firstly, despite the convenience of left-handed users, symmetrical button design would create extra buttons and hence inevitably confuse users. Also, Project Manager pointed out that left-handed users have no difficulty handling the remote control by either side of hands. User Interface added that a thumb was sufficient for this motion, so no difference should exist between left and right.
