an operating portion comprising an operation surface on which a touch operation is performed to select one of the plurality of images displayed on the display unit; a vibration presentation unit that presents tactile sensation by vibrating the operation surface according to the touch operation; and a control unit that extracts at least one candidate image, which has a probability of being selected next after a selected image selected on the operation surface, from the plurality of images displayed on the display screen, predicts a next selected image to be selected next from the candidate image(s) based on a trajectory, on the display screen, of a tracing operation as the touch operation performed on the operation surface, and does not present tactile sensation by the vibration presentation unit even when the trajectory crosses a boundary line acting as a trigger for presenting tactile sensation if it is between the selected image and the next selected image, and presents tactile sensation by the vibration presentation unit when reaching the next selected image. ### Claim 2 (depends on 1) The tactile sensation presentation device according to claim 1, wherein the control unit extracts the candidate image(s) based on frequency or history of being selected next after the selected image. ### Claim 3 (depends on 1) The tactile sensation presentation device according to claim 1, wherein the control unit extracts the candidate image(s) having a high frequency of being selected next after the selected image. ### Claim 4 (depends on 1) The tactile sensation presentation device according to claim 1, wherein the control unit extracts the candidate image(s) of which frequency of being selected next after the selected image is from the highest to a predetermined level. ### Claim 5 (depends on 1) The tactile sensation presentation device according to claim 1, wherein the control unit predicts the next selected image from the candidate image(s) based on the direction of the trajectory. ### Claim 6 (depends on 1) The tactile sensation presentation device according to claim 1, wherein, when the direction of the trajectory deviates from the next selected image and the candidate image is located in a deviated direction, the control unit sets the candidate image as the next selected image. ### Claim 7 (depends on 1) The tactile sensation presentation device according to claim 1, wherein, when the direction of the trajectory deviates from the next selected image and the candidate image is not located in the deviated direction, the control unit causes the vibration presentation unit to present tactile sensation when the trajectory crosses the boundary line. ### Claim 8 (depends on 5) The tactile sensation presentation device according to claim 5, wherein the control unit predicts the direction of the trajectory by detecting a plurality of touch positions on the operating portion after a predetermined time elapsed since the selected image was selected. ### Claim 9 (depends on 1) The tactile sensation presentation device according to claim 1, wherein the operating portion comprises a touch panel superimposed on the display unit. ### Claim 10 A tactile sensation presentation method comprising: extracting at least one candidate image, which has a probability of being selected next after a selected image, from a plurality of images displayed on a display screen; predicting a next selected image to be selected next from the candidate image(s) based on a trajectory, on the display screen, of a tracing operation performed on an operation surface; and not presenting tactile sensation even when the trajectory crosses a boundary line acting as a trigger for presenting tactile sensation if it is between the selected image and the next selected image, and presenting tactile sensation when reaching the next selected image.
