Awareness level improvement device

An awareness level improvement device for improving an awareness level of a driver, comprising:

• an input portion into which data related to the awareness level of the driver is input;
• a determination portion that determines whether the driver is driving in an absentminded state, in which the awareness level of the driver is higher than that of a drowsy driving state and lower than that of a normal driving state, based on the data input into the input portion;
• and
• a controller that controls an execution portion to execute one of a plurality of applications improving the awareness level of the driver when the determination portion determines that the driver is driving in the absentminded state, wherein
• the plurality of applications include a body motion application that prompts the driver to perform a body motion,
• the plurality of applications are classified into a low-stimulus group where stimulus to the driver is low and a high-stimulus group where stimulus to the driver is high,
• the controller executes one of the plurality of applications from the high-stimulus group when an elapsed time of the absentminded state exceeds a reference time, and
• the controller executes one of the plurality of applications from the low-stimulus group when the elapsed time of the absentminded state is below the reference time.
