Computer programs and control methods

Abstract

To enable users to smoothly select from multiple options. [Solution] Information corresponding to one of the multiple selection candidates is displayed on the display unit, and when an operation to display the next candidate is detected while information corresponding to one of the candidates is displayed, the display switches to the information corresponding to the next selection candidate (S810). Based on past operation history, when it is determined that the operator tends to hesitate when selecting one from the candidates (S804:Y), if there is a selection candidate with a higher recommendation level (S806:Y), a special display process is performed in which it is displayed in a different format from the display format corresponding to the other selection candidates (S808). In the special display process, a display can be made that is intended to pique the user's interest.

Claims

1. A computer program for operating the control unit of an in-vehicle information terminal device having an operation input unit that accepts operations from an operator, a display unit, a storage unit, and a control unit, Information corresponding to one of the multiple selection candidates is displayed on the display unit. When the operation to display the next candidate is detected while information corresponding to any of the above is displayed, the display switches to the information corresponding to the next selection candidate. When the operation to display the next candidate is detected while the information corresponding to the final-ranked candidate among the multiple selection candidates is being displayed, a cyclical display switching is performed to display the information corresponding to the first-ranked candidate among the multiple selection candidates again. When a decision operation is detected while information corresponding to one of the aforementioned multiple selection candidates is displayed, the system transitions to another information display state related to the selection candidate corresponding to the currently displayed information. The number of times the operation to display the next candidate is performed before the operation to determine the decision is detected is called the number of display switching operations, and when the period from the start of displaying the information corresponding to the first selection candidate in the display order until the operation to determine the decision is detected and the state of displaying the other information is transitioned is defined as one session, the number of display switching operations is stored in the storage unit each time one session is completed. When a new session is started, if the average number of display switching operations for each session stored in the memory unit is equal to or greater than a predetermined threshold value, a special display process is performed to display at least one of the selection candidates with a higher recommendation level among the multiple selection candidates in a different format than the display format for the other selection candidates. A computer program characterized by the following features.

2. In the computer program described in claim 1, The predetermined value is a computer program characterized by being the number of display switching operations performed in which a cyclical display is performed for one or more cycles within a single session.

3. In the computer program according to claim 1 or 2, A computer program characterized in that, when a new session is started, if the average number of display switching operations for each session stored in the memory unit is equal to or greater than a predetermined threshold value, the display order for the selection candidate with the higher recommendation level among the multiple selection candidates is set higher than the originally set display order.

4. In the computer program according to claim 1 or 2, The computer program is characterized in that the special display processing is a process that displays information in a way that encourages the operator to take an interest in the selection candidates that correspond to the displayed information.

5. In the computer program according to claim 1 or 2, Identify the operator of the in-vehicle information terminal device, The information corresponding to the identified operator and the number of display switching operations are associated and stored in the storage unit. A computer program characterized in that it performs the special display processing if the average number of display switching operations performed per session by a specified operator is equal to or greater than a predetermined threshold value.

6. In the computer program described in claim 5, The aforementioned operation input unit is a touch panel input unit. A computer program characterized by identifying the operator based on the operator's habits when operating the touch panel input unit.

7. A control method for controlling an in-vehicle information terminal device having an operation input unit that accepts operations from an operator, a display unit, a storage unit, and a control unit, Information corresponding to one of the multiple selection candidates is displayed on the display unit, When the operation to display the next candidate is detected while information corresponding to any of the above is displayed, the display switches to the information corresponding to the next selection candidate, When the operation to display the next candidate is detected while the information corresponding to the final-ranked candidate among the multiple selection candidates is being displayed, a cyclical display switching is performed to display the information corresponding to the first-ranked candidate among the multiple selection candidates again. When a decision operation is detected while information corresponding to one of the aforementioned multiple selection candidates is displayed, the system transitions to another information display state related to the selection candidate corresponding to the currently displayed information. The number of times the operation to display the next candidate performed before the decision operation is detected is called the number of display switching operations, and when the period from the start of displaying the information corresponding to the first display rank selection candidate until the decision operation is detected and the state of displaying the other information is transitioned is defined as one session, the number of display switching operations is stored in the storage unit each time one session is completed. When a new session is started, if the average number of display switching operations for each session stored in the memory unit is equal to or greater than a predetermined threshold value, a special display process is performed to display at least one of the selection candidates with a higher recommendation level among the multiple selection candidates in a different format than the display format for the other selection candidates. A control method characterized by having the following features.
