Data transmitter and method for data transmission
A data transmitter to be mounted on a vehicle detects the driver's state from output data of a camera mounted on the vehicle. The data transmitter determines whether the driver's state is suitable for continuing the control by the level of autonomous driving; transmits, when it is determined that the state is suitable for continuing the control, the face image to a terminal communicably connected via a communication network, together with a first setting for displaying the face image on the terminal in first mode; and transmits, when it is determined that the state is unsuitable for continuing the control, the face image to the terminal, together with a second setting for displaying the face image on the terminal in second mode that draws more attention of a user of the terminal than the first mode.
1. A data transmitter to be mounted on a vehicle under travel control by a level of autonomous driving in which a driver need not be alert, the data transmitter comprising a processor configured to:
detect the driver's state from output data of an interior sensor mounted on the vehicle, the interior sensor including a camera that outputs a face image representing the driver's face;
determine whether the driver's state is suitable for continuing the control by the level of autonomous driving;
transmit, when it is determined that the state is suitable for continuing the control, the face image to a terminal communicably connected via a communication network, together with a first setting for displaying the face image on the terminal in first mode; and
transmit, when it is determined that the state is unsuitable for continuing the control, the face image to the terminal, together with a second setting for displaying the face image on the terminal in second mode that draws more attention of a user of the terminal than the first mode.
2. The data transmitter according to claim 1 , wherein the processor
further outputs a suitability level indicating how much the state is suitable for continuing the control, in the determination, and
further transmits, to the terminal, level data for displaying the suitability level on the terminal, in the transmission.
3. The data transmitter according to claim 1 , wherein in the detection, the processor detects a looking direction or a face orientation of the driver from the face image, determines a waking level of the driver, based on the looking direction or the face orientation, and detects the state, depending on the waking level.
4. A method for data transmission executed by a data transmitter mounted on a vehicle under travel control by a level of autonomous driving in which a driver need not be alert, the method comprising:
detecting the driver's state from output data of an interior sensor mounted on the vehicle, the interior sensor including a camera that outputs a face image representing the driver's face;
determining whether the driver's state is suitable for continuing the control by the level of autonomous driving;
transmitting, when it is determined that the state is suitable for continuing the control, the face image to a terminal communicably connected via a communication network, together with a first setting for displaying the face image on the terminal in first mode; and
transmitting, when it is determined that the state is unsuitable for continuing the control, the face image to the terminal, together with a second setting for displaying the face image on the terminal in second mode that draws more attention of a user of the terminal than the first mode.
5. A non-transitory computer-readable medium storing a computer program for data transmission causing a computer mounted on a vehicle to execute a process, the vehicle being under travel control by a level of autonomous driving in which a driver need not be alert, the process comprising:
detecting the driver's state from output data of an interior sensor mounted on the vehicle, the interior sensor including a camera that outputs a face image representing the driver's face;
determining whether the driver's state is suitable for continuing the control by the level of autonomous driving;
transmitting, when it is determined that the state is suitable for continuing the control, the face image to a terminal communicably connected via a communication network, together with a first setting for displaying the face image on the terminal in first mode; and
transmitting, when it is determined that the state is unsuitable for continuing the control, the face image to the terminal, together with a second setting for displaying the face image on the terminal in second mode that draws more attention of a user of the terminal than the first mode.
