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.A method for
projecting data in a portable phone includes the steps of: providing the
handset with the data projection system, conducting a two way
conversation with the handset held against the head of the user, and
forming the visual image on the viewing surface during the two way
conversation with the handset held against the head. The method can also
include the steps of manipulating the handset and a body part to locate
and focus the visual image, sensing an orientation of the handset during
the two way conversation, and orienting the visual image as a function of
the sensing step.
