There are many fun uses of technology by Japanese retailers to encourage more shopper engagement.

John Yong reports for designtaxi.com that: “Japanese clothing retailer United Arrows has found an innovative way to make customers pay attention to its display windows. It uses two ‘MarionetteBots’, half mannequins-half robots capable of mimicking the movements of customers that walk in front of the display windows. And it utilizes Kinect technology and a series of wires, to allow the mannequins to copy the movement of any person — similar to a marionette.” 

Take a look at a YouTube video about United Arrows.
