Abstract
This system provides information delivery that can minimize the likelihood of causing discomfort to users when alerting them using an agent-based HMI while they are on board a mobile vehicle. [Solution] The information provision system 1 comprises a risk recognition unit 14 that recognizes a predetermined risk facing a moving object, and an agent control unit 13. The agent control unit 13 sets the agent's emotions according to emotion levels corresponding to happiness and sadness. When the agent's emotions are set to a first emotion level, and the risk recognition unit 14 switches from a state where the predetermined risk is not recognized to a state where the risk recognition unit recognizes the predetermined risk, the agent's emotions are changed to a second emotion level with a lower degree of happiness than the first emotion level, and the agent outputs the warning voice.
