Claim Text:
1. A mobile terminal comprising: a wireless communication unit; a holography storing medium configured to record an interference pattern generated by interference of light; a holography output module configured to output a holography image attributed to a diffraction between the light applied to the holography storing medium and the interference pattern; a user input unit configured to designate at least one holography pattern corresponding to each of a plurality of keywords; and a controller configured to: control the holography output module to output the holography image in accordance with at least one previously set holography pattern in response to an event occurring on the mobile terminal, and if at least one of the plurality of the keywords is included in message information received via the wireless communication unit or caller information in a call connection attempt received via the wireless communication unit, control the holography image to be output in accordance with the holography pattern corresponding to the included keyword, wherein the at least one holography pattern is automatically determined in accordance with a change of a preset condition, and the preset condition varies in accordance with time.
