<P>PROBLEM TO BE SOLVED: To provide a presentation system which is compatible to multiple functions while miniaturizing a remote controller or dispensing with it, and smoothly proceeds the presentation. <P>SOLUTION: A function key 80 is composed by fixing a key top 82 on which a function display 83 representing the function for the presentation and a bar code 84 related to the function for the presentation are displayed to an arbitrary holder 81 mounted on a function board 60. The bar code 84 emerges when an infrared light lamp 88 on the background is ignited by pushing the key top 82. The bar code 84 is picked up with an imaging part 40, a controlling part 31 discriminates the bar code 84 from the picked-up image, and carries out the function for the presentation related to the bar code 84. <P>COPYRIGHT: (C)2004,JPO |
