Systems and methods for controlling a cursor on a display using a trackpad input device are disclosed. The systems and methods may be directed to controlling the cursor on a display separate from the trackpad input device, based on information identified about a motion of a trackpad input device or a computing device. A conversion factor may be determined to relate input to the trackpad input device with control of the cursor on the display in response to the input. The conversion factor can be adjusted when the motion information indicates that the trackpad input device or computing device is in motion. An input signal from an input to the trackpad input device may be smoothed by filtering out a mechanical vibration signal within the input signal. The input signal may also be smoothed by subtracting the absolute motion of the trackpad input device from the input signal.
