A vehicular input device comprising: a position detection unit that is disposed within a vehicle cabin, has an operative input surface on which a user performs an operative input, and is configured to detect a position of the operative input performed on the operative input surface; a display unit that is disposed within the vehicle cabin and is configured to display at least three objects in a linear arrangement, the objects being selectable by the operative input; and an electronic control unit configured to determine, based on a movement amount of the position of the operative input, a current object from the displayed objects, display a selection image that indicates on the display unit that the current object is selected; set a determination threshold of the movement amount of the operative input used in determination of movement of the selection image to a next object from the current object to be smaller than a determination threshold of the movement amount of the operative input used in determination of movement of the selection image to a second next object from the next object, and determine whether the position of the operative input is being moved; determine whether the position of the operative input is stopped for one second or longer, when the electronic control unit determines that the position of the operative input is not being moved; and set the current position of the operative input as a starting point of measuring the movement amount, when the electronic control unit determines that the position of the operative input is stopped for one second or longer. a position detection unit that is disposed within a vehicle cabin, has an operative input surface on which a user performs an operative input, and is configured to detect a position of the operative input performed on the operative input surface; a display unit that is disposed within the vehicle cabin and is configured to display at least three objects in a linear arrangement, the objects being selectable by the operative input; and an electronic control unit configured to determine, based on a movement amount of the position of the operative input, a current object from the displayed objects, display a selection image that indicates on the display unit that the current object is selected; set a determination threshold of the movement amount of the operative input used in determination of movement of the selection image to a next object from the current object to be smaller than a determination threshold of the movement amount of the operative input used in determination of movement of the selection image to a second next object from the next object, and determine whether the position of the operative input is being moved; determine whether the position of the operative input is stopped for one second or longer, when the electronic control unit determines that the position of the operative input is not being moved; and set the current position of the operative input as a starting point of measuring the movement amount, when the electronic control unit determines that the position of the operative input is stopped for one second or longer. determine, based on a movement amount of the position of the operative input, a current object from the displayed objects, display a selection image that indicates on the display unit that the current object is selected; set a determination threshold of the movement amount of the operative input used in determination of movement of the selection image to a next object from the current object to be smaller than a determination threshold of the movement amount of the operative input used in determination of movement of the selection image to a second next object from the next object, and determine whether the position of the operative input is being moved; determine whether the position of the operative input is stopped for one second or longer, when the electronic control unit determines that the position of the operative input is not being moved; and set the current position of the operative input as a starting point of measuring the movement amount, when the electronic control unit determines that the position of the operative input is stopped for one second or longer.
