Claim of US Patent No. 10,602,595

1. A method for controlling an illumination level of a luminous element of a user interface for an electrical device, comprising:storing, by a processor, information defining a signal corresponding to a desired time-varying illumination level of the luminous element to be perceived by a human observer, wherein the corresponding signal comprises an increasing sinusoidal-based ramp function and a decreasing sinusoidal-based ramp function;
calculating, by the processor, a time-varying control signal based on the corresponding signal and a nonlinear sensitivity relationship between an actual illumination level and a resulting illumination level perceived by a human eye; and
causing, by the processor, the luminous element to be illuminated in accordance with the calculated time-varying control signal.
