A method for data communication is provided and may include, at a communications terminal, displaying picture objects and/or video objects received from a media center via a communications network. The communications terminal may transmit direction of view information (DoV) of at least one eye of a user of the terminal with respect to the displayed objects from an eye tracker at the communications terminal. The DoV may be determined by detecting a position of a pupil based on light reflected off of the pupil. Subsequent picture objects and/or video objects may be displayed by the communications terminal based on user interests determined from the transmitted DoV information. The DoV information may be determined using: a beam splitter, a lens, and a position sensing diode which receives light from the lens which has been received from the beam splitter, wherein the position sensing diode outputs a signal to the eye tracker. |
