A method in an activity tracking apparatus configured to be worn by a user includes obtaining, by the activity tracking apparatus, motion data from one or more sensors, wherein the motion data characterizes motion of the activity tracking apparatus; and controlling, based on the motion data, characteristics of a vibration causing a haptic output, wherein the haptic output is configured to be output as a response to an event on the activity tracking apparatus. Corresponding apparatus and computer programs are also disclosed.
