An information processing system comprising: An image processing unit which displays images on a display; and a processing executing unit (20, 28) which executes processes according to at least one of a plurality of options displayed in a menu image on the said display, wherein the said image processing unit displays an indicator image along the edge of a display part, and in that the said information processing system is furnished with a touch sensor comprising an inner area occupying the display surface of the display, and an outer area which is an area outside and adjacent to the said display surface, and when a slide operation of an object across the indicator image from the outer area toward the inner area is detected by the touch sensor, which detects the positions of an object on the touch sensor area and which is capable of detecting the relevant position even when this extends into the said outer area, a menu image is displayed in which a plurality of options are aligned and in which the option with the shortest distance from the position detected by the said touch sensor is highlighted, whereby when the said touch sensor detects detection results corresponding to the movement of the object by the user in a direction along the edge of the said display surface on which the said plurality of options are aligned, the said information processing system changes the option which is highlighted accordingly with the detection results, and whereby when the said touch sensor has detected detection results corresponding to further movement of the object by the user in a direction towards the middle part of the said display surface, processing is executed based on the option which is highlighted.
