A handheld device for canceling unintentional muscle movement. The device includes a base comprising a handgrip for a user to hold, a gripping element linked to the base for releasably connecting the handheld device to an object, a sensor that detects movement of the base, a controller linked to the sensor, and at least one actuator that operates under control of the controller to cause movement of the gripping element in a direction that at least partially counteracts the detected movement of the base.
