iHeartrate: a heart rate controlled in-flight music recommendation system

Travel by air, especially long distance, the enclosed environment of the aircraft cabin causes discomfort and even stress to flight passengers. In this paper, we present a new heart rate controlled music recommendation system. Heart rate is used as a stress indicator. If the user is stressed and his/her heart rate is higher/lower than normal, the system recommends a user preferred calm/uplift music playlist to transfer the heart rate back to normal; An user experiment is done to validate our system. The experiment results not only show that our system keeps the user's heart rate at normal but also show that the passenger's stress level can be reduced by our system.
