Abstract: A portable phone includes a handset and a data projection system configured to form a visual image of data, such as caller waiting ID data, on a viewing surface viewable by a user during a two way conversation. The handset also includes a speaker, a microphone, conventional phone circuitry and a keyboard. The data projection system is configured to receive signals from the phone circuitry, to generate a pattern representative of the data, to process the pattern into a mirror image of the visual image, and to project the mirror image from a bottom end surface of the handset. The projection system includes an electro optic system for generating the pattern, and an optics system for projecting the mirror image onto the viewing surface.
