An input device having a manipulation member is disclosed. The input device has an absolute input mode and a relative input. In the absolute input mode, the input device determines a coordinate of a pointed point on a window of a display unit based on a coordinate of the manipulation member. In the relative input mode, the input device determines the pointed point on the window in a relative manner based on a two-dimensional displacement of the manipulation member with respect to a reference position, which is set when an input mode is switched into the relative input mode. When the manipulation member receives a load that causes the manipulation member to move beyond a predetermined range, the input device generates and applies a force corresponding to the load to the manipulation member.
