<P>PROBLEM TO BE SOLVED: To provide an input display device constituted so as to improve operability to a plurality of keys while suppressing deterioration of an appearance. <P>SOLUTION: Touch positions touched by an operator are specified for every key (S120), presence/absence of erroneous input (S130) and its content are sampled based on detection of reaction areas which can be set for every key. When the number of samples is equal to or more than a default value (S170), distribution of the specified touch positions is calculated for every key (S180), reaction areas for every key are determined (S220) so as to expand the reaction areas for every key in the direction in which the touch positions are eccentrically distributed based on the calculated distribution of the touch positions. Since it becomes possible to match the reaction areas for every key to an operation state of the operator, and since operability to a plurality of keys is improved, on the other hand, size of the display area is not changed, deterioration of appearance is suppressed. <P>COPYRIGHT: (C)2013,JPO&INPIT |
