Abstract

A data processing device for performing suitable feedback with regard to a pointing gesture of a vehicle occupant is provided. The occupant state recognition unit recognizes motion of an occupant of the vehicle pointing to outside the vehicle. The peripheral conditions acquisition unit acquires the peripheral circumstances around the vehicle. The target recognition unit recognizes a target pointed at by the occupant based on recognition results obtained by the occupant state recognition unit and recognition results obtained by the peripheral conditions acquisition unit. The light emitting unit has a long shape and is installed above or below a windshield of the vehicle over a vehicle body width direction. The light emission control unit controls, in two stages, a luminescence mode for a portion of the light emitting unit corresponding to a direction pointed at by the occupant and/or a direction in which the target is located.

First claim

What is claimed is:

1 . A data processing device mounted on a vehicle, comprising:
an occupant state recognition unit that recognizes motion of an occupant of the vehicle pointing to outside of the vehicle; a peripheral conditions acquisition unit that acquires peripheral conditions around the vehicle; a target recognition unit that recognizes a target pointed at by the occupant based on the recognition result obtained by the occupant state recognition unit and the recognition result obtained by the peripheral conditions acquisition unit; and a light emission control unit connected to an elongated light emitting unit installed above or below a windshield of the vehicle over a width direction of the vehicle, and configured to control a luminescence mode in a portion of the elongated light emitting unit corresponding to the direction pointed to by the occupant or the direction in which the target is located in at least two stages based on the recognition result of the occupant state recognition unit or the recognition result of the target recognition unit, wherein in the control with at least two stages, a width of a portion of the light emitting unit that emits light varies depending on a recognition stage of the occupant state recognition unit and/or a recognition stage of the target recognition unit.

2 . The data processing device according to claim 1 , wherein, the light emission control unit changes the luminescence mode depending on whether or not the occupant state recognition unit recognizes a direction pointed at by the occupant.

3 . The data processing device according to claim 1 , wherein, the light emission control unit changes the luminescence mode depending on whether or not the target recognition unit recognizes a target pointed at by the occupant.

4 . The data processing device according to claim 3 , wherein the light emission control unit illuminates a portion of the elongated light emitting unit including the direction pointed at by the occupant across a first width when the occupant state recognition unit recognizes the direction pointed by the occupant, and illuminates a portion of the light emitting unit including a direction in which the target is located across a second width when the target recognition unit recognizes the target pointed at by the occupant; the second width is narrower than the first width.

5 . The data processing device according to claim 1 , further comprising a parking assistance unit that assists parking in a designated parking region;
wherein the peripheral conditions acquisition unit acquires an image from a camera that captures an image of surroundings of the vehicle; and the target recognition unit recognizes a parking region in which the vehicle can park from the image as the target and outputs the recognized parking region to the parking assistance unit.

6 . The data processing device according to claim 1 , further comprising a destination setting unit that sets a specified facility as a destination;
wherein the peripheral conditions acquisition unit acquires map data around the vehicle; and the target recognition unit recognizes a facility included in the map data as a target and outputs the recognized facility to the destination setting unit.

7 . A method for recognizing motions of an occupant in a vehicle and providing feedback to the occupant, comprising:
a first step of recognizing a motion of an occupant pointing outside the vehicle; a second step of acquiring peripheral conditions around the vehicle; a third step of recognizing a target pointed at by the occupant based on the recognition result by the first step and the acquisition result by the second step; and a fourth step of controlling a luminescence mode in a portion of a light emitting unit in at least two stages, the light emitting unit has an elongated shape and installed above or below a windshield of the vehicle over a width direction of the vehicle, the portion is controlled to corresponds to the direction pointed at by the occupant or the direction in which the target is located based on the recognition result by the first step or the recognition result by the third step, wherein in the control with at least two stages, a width of a portion of the light emitting unit that emits light varies depending on a recognition stage of the occupant state recognition unit and/or a recognition stage of the target recognition unit.
