When the finger is moved onto the guidance path 213, the contacted finger is separated from the display panel 67 to perform a drop operation. When the drop operation is detected, the control unit 100 superimposes and displays the pattern figure 215A along the display of the guidance path 213.

The pattern figure 215A is an image showing the playback time of the selected music, and the length of the pattern figure 215A is based on the ratio of the time required to reach the destination and the playback time of the selected music. It is determined. Further, the color and pattern of the figure displayed as the pattern figure 215 may be changed for each musical piece. The pattern figure 215A corresponds to an example of a "figure".

For example, when the playback time of the selected music and the time required to reach the destination match, the pattern figure 215A is displayed from the icon 211 indicating the current position of the vehicle to the icon 212 indicating the destination. When the playback time of the selected music is shorter than the time required to reach the destination, the pattern figure 215A is displayed from the icon 211 indicating the current position of the vehicle to the middle of the guidance path 213. At this time, the length of the pattern figure 215A is determined by the ratio of the required time to the reproduction time. For example, if the time required to reach the destination is 60 minutes and the playback time of the selected song is 30 minutes, the pattern figure is from the icon 211 indicating the current position of the vehicle to the half point of the guidance route 213. 215 is displayed. Further, when the playback time of the selected music is longer than the time required to reach the destination, the pattern figure 215A is displayed beyond the point where the icon 212 indicating the destination is displayed, as shown in FIG. ..

Further, the symbol 217 is displayed at the start point and the end point of the pattern figure 215A. The symbol 217 displayed on the start point side is referred to as symbol 217A, and the symbol 217 displayed on the end point side is referred to as symbol 217B. When the control unit 100 detects the touch operation on the symbol 217A or the symbol 217B and determines that the time for the touch operation on the symbol 217A or the symbol 217B continues for a predetermined time or longer, the control unit 100 displays the touched symbol 217A or the symbol 217B. Is changed to the display of the slide button 219. The slide button 219 corresponds to an example of a "marker".

In addition, the guidance display 230 is displayed on the navigation screen 210.
The guidance display 230 displays a display based on the relationship between the playback time of the selected music and the required time. For example, if the playback time of the selected song is longer than the required time, a display such as "Arrive near the destination while playing the selected song" is displayed.

FIG. 6 is a diagram showing an application screen 200. In particular, FIG. 6 is a diagram showing a state in which the slide button 219 is displayed.
The slide button 219 displayed when the symbol 217A on the start point side is touched is referred to as a slide button 219A, and the slide button 219 displayed when the symbol 217B on the end point side is touched is referred to as a slide button 219B.
The slide button 219 displays an arrow indicating the moving direction in which the slide button 219 can move. Since the slide button 219 can be moved along the extending direction of the guiding path 213, the arrow is also displayed in the direction along the extending direction of the guiding path 213. On the slide button 219, an arrow indicating a direction for extending the length of the pattern figure 215A and an arrow indicating a direction for shortening the length of the pattern figure 215A are displayed.

The user touches the display position of the slide button 219 with a finger, and moves the touched finger in the direction indicated by the arrow. If the time required to reach the destination is longer than the playback time of the selected music and all the selected music can be played, the slide button 219 is in the direction of extending the length of the pattern figure 215A. I can't move it. When the slide button 219 is moved in the direction of shortening the length of the pattern figure 215A, the display of the pattern figure 215A is also changed as the display position of the slide button 219 is changed.

FIG. 7 is a diagram showing an application screen 200. In particular, FIG. 7 is a diagram showing a display state of the application screen 200 when the slide button 219 is slid.
For example, when the slide button 219B displayed near the icon 212 indicating the destination is moved in the direction of the icon 211 indicating the vehicle along the guidance path 213, the pattern figure 215A is displayed in accordance with the movement of the slide button 219B. Is also shortened.

When the movement of the finger is stopped, the control unit 100 identifies the position of the stopped finger on the guidance path 213.
