PROBLEM TO BE SOLVED: To provide an operation system whose operability is improved.SOLUTION: An operation system includes: a sensor part which has a rough structure on its surface, and detects a position which is contacted by a contact body and outputs a position signal representing a position of the detected contact body; a display part which displays an image that corresponds to the surface of the sensor part and includes a plurality of operation key images; and a selection part which selects an operation key image corresponding to the position of the contact body among the plurality of operation key images displayed on the display part, and makes a position of the contact body for switching selection of operation key images different between a case in which a continuous change of the position signal shows a first direction and a case in which the continuous change of the position signal shows a second direction which is opposite to the first direction. |
