ABSTRACT

WITH THE CROSS DEVELOPMENT OF NEUROSCIENCE AND ARTIFICIAL INTELLIGENCE, THE BIO SIGNAL-BASED ENVIRONMENTAL ADAPTIVE TECHNOLOGY HAS BECOME A RESEARCH  FRONTIER IN THE FIELD OF SMART HOME. IN THIS PAPER, WE PROPOSE A SMART  AROMATHERAPY MACHINE SYSTEM THAT CAN COMBINE BRAINWAVE (EEG) MONITORING  AND AI-DRIVEN, AIMING TO ACHIEVE DYNAMIC OPTIMISATION OF THE HOME  ENVIRONMENT THROUGH REAL-TIME EEG SIGNAL ANALYSIS. THE STUDY FIRST BUILDS A  MULTIMODAL DATA ACQUISITION MODULE TO EXTRACT THE CHARACTERISTIC FREQUENCY  BANDS SUCH AS Α-WAVE AND Β-WAVE TO IDENTIFY THE USER'S RELAXATION,  CONCENTRATION OR FATIGUE STATE. SECONDLY, A LIGHTWEIGHT DEEP LEARNING MODEL IS  DESIGNED TO CLASSIFY EEG SIGNALS IN REAL-TIME AND ENSURE LOW-LATENCY  INTERACTION THROUGH EDGE COMPUTING ARCHITECTURE. THE SYSTEM DYNAMICALLY  REGULATES THE AROMATHERAPY MACHINE BASED ON THE CLASSIFICATION RESULTS. USERS  CAN SELF-SELECT A THEME IN THE SYSTEM ACCORDING TO THEIR PREFERENCES OR  EMOTIONS, AND THEN THE AROMATHERAPY DEVICE RELEASES THE CORRESPONDING AROMA  ACCORDING TO THE SELECTED THEME TO HELP THE USER FALL ASLEEP MORE EASILY.  DURING SLEEP, THE SYSTEM CONTINUOUSLY TRACKS THE USER'S SLEEP DYNAMICS  THROUGH AN INTEGRATED SLEEP MONITORING APPLICATION, WHICH TRANSMITS THE DATA TO  THE DEVICE. AT THE SAME TIME, THE SYSTEM COLLECTS AND ANALYSES DETAILED DATA ON  SLEEP QUALITY, DREAM ACTIVITY AND SCENT ADJUSTMENT TO GENERATE A  COMPREHENSIVE REPORT THAT IS SENT TO THE USER'S SMARTPHONE.  THIS INNOVATIVE DESIGN NOT ONLY ENHANCES THE USER EXPERIENCE, BUT ALSO  PROVIDES A SCIENTIFIC BASIS FOR ASSESSING INDIVIDUAL SLEEP CONDITIONS. CURRENT  RESEARCH SHOWS THAT AROMATHERAPY HAS A POSITIVE EFFECT ON IMPROVING SLEEP  QUALITY AND RELIEVING ANXIETY SYMPTOMS.  HOWEVER, THERE IS STILL A LACK OF RESEARCH ON THE DYNAMIC ADJUSTMENT OF  FRAGRANCE BASED ON REAL-TIME SLEEP DATA. THIS STUDY AIMS TO FILL THIS GAP BY  DEVELOPING A SYSTEM THAT ENABLES PERSONALISED FRAGRANCE RELEASE BASED ON USER  PREFERENCES AND REAL-TIME SLEEP MONITORING DATA, PROVIDING USERS WITH AN  UNPRECEDENTED SLEEP EXPERIENCE.
