Patent attributes
The present invention includes a user input unit, a controller, a holography storing medium configured to record an interference pattern generated by interference of light, a holography output module configured to output a 1st holography image attributed to diffraction between the light applied to the holography storing medium and the interference pattern under the control of the controller, and a sensing unit configured to detect a plurality of recognition based events, wherein if at least one holography function corresponding to each of a plurality of the recognition based events is previously designated via the user input unit and a 1st event among a plurality of the recognition based events is detected via the sensing unit, the controller controls the 1st holography image to be outputted in accordance with a 1st holography function corresponding to the 1st event.
