Input device of mobile devices
A rotator wheel is mounted on the device in such a way that its rim can be reached with the finger from at least one side. This enables the user to operate the rotator wheel like a roller. The rotator wheel can be equipped with sensors or switches that detect if the rotator wheel is being operated from the top, from bottom or from the side. The function assigned to the wheel can be changed accordingly.
