1. A method for dispensing at least one scent medium into an atmosphere to prolong a user's perception of the at least one scent medium, the method comprising:
gathering information on the user's perception of the at least one scent medium,
wherein the user's perception of the at least one scent medium comprises determining an upper- and a lower-intensity level of the at least one scent medium in the atmosphere;
increasing a concentration of the at least one scent medium to the upper-intensity level in the atmosphere during a first time period;
decreasing the concentration of the at least one scent medium to the lower-intensity level in the atmosphere during a second time period; and
increasing the concentration of the at least one scent medium or another scent medium in the atmosphere during a third time period,
wherein the third time period is the first time period defining a repetitive rhythm for the dispersing the at least one scent medium into the atmosphere, and
wherein the rhythm is configured to avoid adaptation of the user's perception to the at least one scent medium.
