REMEMBER the vending machines in New York City subway stations, even on platforms? (O.K., maybe not, as it was decades ago.) Among the products straphangers could buy were cigarettes, candy and gum; there were also scales proclaiming, “Horoscope and weight 1¢.”

The beauty giant L’Oréal wants to revisit that era in a high-tech way with a project it is sponsoring inside the 42nd Street-Bryant Park station from Monday through Dec. 30. Passers-by will see screens and a mirror that use cameras and sensors to recommend women’s cosmetics bearing the L’Oréal Paris brand name, which can then be purchased.

The project, called the L’Oréal Paris Intelligent Color Experience, is being described by the participants as an entry in the realm of interactive shopping outside of traditional stores. It is another example of a trend known as experiential marketing, which seeks to give brands more tangible form beyond retail shelves.

The goal is a “real-life experience through technology,” said Marc Speichert, chief marketing officer at the L’Oréal Americas unit of L’Oréal. “If this experiment is successful, we might bring it to other places.”
