  • Publication number: 20230373496
    Abstract: In a technique for vehicle control, a gesture due to a motion of a body part of an occupant of a vehicle is detected. The gesture is associated with an operation of an in-vehicle device provided in the vehicle. The in-vehicle device executes the operation associated with the gesture. The in-vehicle device executes position-specific operations that are different for respective positions in a vehicle cabin of the vehicle. The gesture requires a line motion of the body part. Different operations of the position-specific operations are associated with gestures detected as a common gesture according to a direction of trajectory deviation. The trajectory deviation is deviation of a trajectory of a line motion of the body part detected as the common gesture from a trajectory of the line motion required by the common gesture.
