The work aims to explore the practical effect of sleep-aid music recommendation design based on emotional perception and verify its feasibility and gain further insight into the optimization space by testing its effectiveness in emotion regulation and sleep induction. According to the guidance of perceived emotion on induced emotion, the music sequence recommendation logic and interaction interface were designed with the smart bed as the hardware carrier characterized by music information, sequence selection guidance and playback settings in the music sleep-aid scenario. Prototype evaluation experiments were carried out to verify its effect in emotion regulation and sleep aid and analyze its mutual differences in different sequences of design. In addition, the interface design was further optimized combined with the interview data feedback and the usability was verified. In terms of emotion regulation, the music sequences arranged according to arousal and valence in order had the best regulation effect in their corresponding dimensions. Sequences based on the weight of favoritism and familiarity performed best in regulating comprehensive emotions. In terms of sleep-aid effect, the music sequence arranged in descending order of arousal and based on the weight of favoritism and familiarity performed best. The application prototype of the sleep-aid music recommendation design strategy proposed from the perspective of emotional perception can effectively regulate users' emotion and produce sleep-aid effects. It also inspires functional experience optimization of corresponding interaction design, and has good practical application value.
