Hitachi developed a mirror that doubles as a computer display. "The mirror combines a half mirror and a diffusion film to directly display digital information (text, photos, video, tv shows, websites, flash movies etc.) on a mirror surface using an LCD projector. This technology, called Miragraphy, also integrates sensors, RFID readers, barcode readers, cameras, etc. So, the mirror can automatically respond when people are aruond and personalize digital contents based on their sensed identities."--RFID in Japan
