Sometimes perception is stronger than reality. At least, that's the idea behind a new form of home security in Japan. Developed as a quick and easy security system for a number of Japanese buildings, Man on the Curtain (as the technology is being dubbed) creates the shadow of a man on window curtains with the aim to stop would-be intruders from breaking in. The technology is such that from an application on a smartphone, a projector throws a moving shadow onto a curtain to create the illusion that more people are home. Designed with single Japanese women in mind, the app casts a shadow that moves in a variety of scenes ranging from karate practice and baseball swings to tying a necktie or playing the guitar.
While the technology is cheap and exciting, it does have its flaws. Should the developers not add more activities to the shadows repertoire, a would-be intruder could, over time, come to realize it's a gimmick, making the home (presumably) more susceptible to an invasion since it would be understood that only one person is home. To combat this, Leopalace21 Corp. (the owner of the buildings that use the technology) is working to develop more iterations, with the intentions of releasing a new shadow each day.
And if there's anyone out there wondering if a similar, albeit lower-tech, version of home security has proved itself before, don't forget Kevin McCallister's iteration in the movie Home Alone (1990). Click here to watch a video Leopalace21 Corp. created to promote its security application.
