method of visually representing the variation over time of a current difference between a real value and an optimum value for a parameter, using at least three activatable light signals

摘要

The invention relates to a method of visually representing the variation over time of a difference between a real value of a parameter and an optimum value thereof using at least three activatable light signals, said method comprising:a first transition step (105) that is performed if the current range of values is contiguous with a prior range of values, in which step, after a first delay has elapsed, the signal associated with the prior range of values is deactivated and the light signal associated with the current range of values is activated; anda second transition step (107) that is performed if the current range of values is not contiguous with the prior range of values, during which step, after a second delay has elapsed, the light signal associated with the prior range of values is deactivated and the light signal associated with an intermediate range of values corresponding to a range of values contiguous with the prior range of values, is activated, and then after a third delay has elapsed, the light signal associated with the intermediate range of values is deactivated and the light signal associated with the current range of values is activated.
