<p><P>PROBLEM TO BE SOLVED: To reduce a deviation between a pen input position on a display screen and a display position on the display screen which is caused when viewing a display device slantwise. <P>SOLUTION: A projecting lens 12 is installed on the front face of a display screen 14 on which an image is displayed. When write is operated to a first contact position 32 by a pen 30 on the front face of the projecting lens 12, a control part 16 displays an image corresponding to the first display position 34 behind it. A light beam from the displayed image is transmitted through an optical path 36 refracted by the projecting lens 12 to the eyes 28 of an input person located at an oblique direction. Thus, when adding write to the same position, the input person is supposed to touch a pen 38 to a second contact position 40 relatively close to the first contact position 32. Therefore, deviation 44 at the display position is reduced compared with the case that the projecting lens 12 is not used. <P>COPYRIGHT: (C)2007,JPO&INPIT</p> |
