A visual indication of user proficiency at interacting with an application program such as a computer game can be provided through a system and/or method configured to determine an actions count corresponding to a number of input device signals generated and/or application program actions initiated during application program execution; normalize the actions count to determine an actions per minute value; and output illumination signals during application program execution using a set of illumination devices such as LEDs carried by an input or output device, where the illumination signals indicate a user performance level relative to a set of actions per minute thresholds. Actions per minute thresholds and/or particular illumination devices corresponding thereto can be selected or programmably specified in response to user input received by way of an illumination control GUI.
