The image is nothing more than a projected shadow but one that a Japanese apartment management company hopes will help protect and reassure women living by themselves.
Still in the prototype stage, "Man on the Curtain" uses a smartphone connected to a projector to throw a moving shadow of a man doing various energetic activities onto a curtain.
Customers can choose from a dozen different scenarios that show their man boxing, doing karate and even swinging a baseball bat.
The system was developed for security at buildings run by Leopalace21 Corp,, said Keiichi Nakamura, manager of the firm's advertising department.
"If projecting a shadow makes a woman an easy target by showing criminals there's nobody home, that would put the cart before the horse," he said.
"So we'd like to commercialise it once we add variety, such as releasing a new video every day."
