The researchers at The Hong Kong Polytechnic University Institute of Textiles and clothing have come up with "An intelligent Simulator for Cross-selling & Up-selling using Smart Fitting Room & Smart Dressing Mirror".

This system makes use of RFID. It detects as to what item has been brought by the customer in the fitting room or positioned in front of the dressing mirror. The system includes readers and antennas that detect the item placed in front of the mirror. A mix and match from the database will then provide recommendations to the customer through a touch screen or LCD projector. The customer can chose the Items from the miw and match items by clicking on the items on the screen.
