PROBLEM TO BE SOLVED: To provide means which improves work efficiency when changing a layout among a plurality of images on a display.SOLUTION: After dividing images 92 to 95 displayed on a multi-touch display into groups, a user can move all images in a group at a time by touching and dragging one image (for example, an image 92) in the group with a first finger. In this case, the same touch ID is set to the images in the group. When the user touches one image (for example, an image 95) in the group with a second finger while maintaining the touch with the first finger, another touch ID is set to the image 95. Thereafter, the image 95 can be moved independently of the other images in the group by drag operation with the second finger. When the second finger is released from the multi-touch display, the touch ID set to the image 95 is reset to the original touch ID, and the image 95 can be moved in accordance with drag operation with the first finger again. |
