The present invention relates to a system for communicating an operational state of a neuronal stimulation apparatus to an individual, comprising: means for determining the operational state of the apparatus; means for transmitting a first neuronal stimulation signal to a neuronal stimulation means of the individual adapted to elicit a sensory percept in the cortex of the individual, wherein the first neuronal stimulation signal is indicative of the operational state of the apparatus. The present invention further relates to a method and computer program comprising the steps of: determining the operational state of the apparatus, transmitting a neuronal stimulation signal to a neuronal stimulation means of the individual adapted to elicit a sensory percept in the cortex of the individual, wherein the first neuronal stimulation signal is indicative of the determined operational state of the apparatus.
