Abstract
An ergonomic scrolling device comprises a shell and a rolling wheel. The rolling wheel is pivotally connected to the shell. The shell has an axial shaft perpendicular to the axis of the rolling wheel and on an external surface of the shell. The shell is rotatable around the axial shaft such that the shell can be rotated leftward or rightward. The rolling wheel is also rotated with the shell to a specific angle for providing more convenience to user.
