Publication number: 20240075874Abstract: 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.Type: ApplicationFiled: August 29, 2023Publication date: March 7, 2024Applicant: Faurecia Clarion Electronics Co.
