Abstract

A vehicular terminal receives an input of a condition via an input unit, such that the input may be performed via manual operation or voice recognition. An input restriction function restricts a reception of the condition by manual operation during vehicle travel. The vehicular terminal determines whether an input reception restriction function is in effect during the reception of the condition by manual operation via the input unit. When it is determined that the input reception restriction function is in, the vehicular terminal switches an input method for reception of the input of the condition from manual operation to voice recognition, thereby allowing a continuous reception of the condition.

Claims

1. A vehicular terminal comprising:

an input unit receiving an input from an input method, the input method including a manual operation input performed by a manual operation and a voice recognition input performed by a voice recognition process;

an input restriction function restricting a reception of a condition by the manual operation input during a travel of a vehicle;

a effectiveness determination unit determining whether the input restriction function is put in effect during reception of the condition by the manual operation input; and

a first input reception switcher switching the input method from the manual operation input to the voice recognition input to continue reception of the condition from the input unit when the effectiveness determination unit determines the input restriction function is in effect.

2. The vehicular terminal of claim 1 further comprising:

a notification unit notifying a user of continuing the input of the condition by enabling the voice recognition input when the effectiveness determination unit determines that the input restriction function is in effect.

3. The vehicular terminal of claim 2 further comprising:

a confirmation unit receiving confirmation from the user of switching the input method from the manual operation input to the voice recognition input after notifying the user of the voice recognition input via the notification unit, wherein

when confirmation to switch the input method to the voice recognition input is received, the first input reception switcher switches the input method from the manual operation input to the voice recognition input.

4. The vehicular terminal of claim 1 further comprising:

an invalidation determination unit determining whether the input restriction function is not in effect after the first input reception switcher switches the input method from the manual operation input to the voice recognition input, and

a second input reception switcher switching the input method from the voice recognition input to the manual operation input or maintaining the input method as the voice recognition input for continuing reception of the input of the condition when the invalidation determination unit determines the input restriction function is not in effect.

5. The vehicular terminal of claim 1 further comprising:

a plurality of display units; and

a display controller displaying on one of the plurality of display units an input screen for receiving the input by at least one of the manual operation input or the voice recognition input and displaying on another one of the plurality of display units a map screen.

6. The vehicular terminal of claim 1 further comprising:

a display unit; and

a display controller displaying on the display unit an input screen for receiving the input by at least one of the manual operation input or the voice recognition input, and displaying a map screen, wherein

the display controller switches from the input screen to the map screen when the effectiveness determination unit determines the input restriction function was put in effect during reception of the input of the condition by the manual operation input.

7. The vehicular terminal of claim 6, wherein

the display controller displays the condition, which is inputted by the input unit, in a first condition display area on the input screen when the condition is received by the manual operation input before the input restriction function is put in effect, and

the display controller displays the condition, which is inputted by the input unit, in a second condition display area on the map screen when the display controller switches from the input screen to the map screen and when the first input reception switcher has switched the input method from the manual operation input to the voice recognition input after the input restriction function is put in effect, the second condition display area displays the condition as it was displayed by the first condition display area and appends it with the inputs received by the voice recognition input.
