Display control device and display control method

A display control device comprising:

• a positional information acquisition unit that acquires positional information representing a current position of a vehicle;
• a route guide unit that acquires information on a guide point where the next leading guide is made from the current position of the vehicle on a route to a destination that the vehicle travels;
• a determination unit that determines whether the current position of the vehicle is within an area of a given distance from the guide point;
• a display controller that changes a display mode of a display screen based on a result of the determining by the determination unit;
• and
• a line-of-sight receiver that receives an operation performed using a line of sight of a person on the display screen,
• wherein the display mode includes a first mode in which music information on music that is being reproduced in the vehicle is displayed and a second mode that is different from the first mode and in which information other than the music information is displayed,
• the line-of-sight operation receiver receives a saving operation of saving information on the music being reproduced using a line of sight in the first mode and causes a storage unit to store the saving information on the music that is being reproduced, and
• the display controller makes a switch from the second mode to the first mode after the guide point is passed, and
• the line-of-sight operation receiver saves the music being reproduced with a high priority when the line-of-sight operation receiver receives the saving operation within a threshold operation time after the switch from the second mode to the first mode is made.

A display control method executed by a computer that operates as a display control device, the method comprising:

• acquiring positional information representing a current position of a vehicle;
• acquiring speed information representing a speed of the vehicle;
• based on the positional information that is acquired by the acquiring the positional information and the speed information that is acquired by the acquiring the speed information, calculating a time required to travel from the current position of the vehicle to a guide point where the next leading guide is made on a route to a destination that the vehicle travels;
• determining whether the required time that is calculated by the calculating is equal to or more than a threshold time;
• changing a display mode of a display screen based on a result of the determining;
• and
• receiving an operation performed using a line of sight of a person on board on the display screen,
• wherein the display mode includes a first mode in which music information on music that is being reproduced in the vehicle is displayed and a second mode that is different from the first mode and in which information other than the music information is displayed,
• the receiving includes receiving a saving operation of saving information on the music that is being reproduced using a line of sight in the first mode and causing a storage unit to store the saving information on the music that is being reproduced, and
• the changing makes a switch from the second mode to the first mode after the guide point is passed, and
• the receiving saves the music being reproduced with a high priority when the line-of-sight operation receiver receives the saving operation within a threshold operation time after the switch from the second mode to the first mode is made.
