Hitachi have announced a new mirror that could also function as an advertising display. It 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 around and personalize digital contents based on their sensed identities.
