Good sleeping quality has a huge effect on daily work or study performance, so we could not underrate its importance. Previous studies used sleeping stage or questionnaire assessment to evaluate sleeping quality. This study tried to propose three new overnight sleep EEG signals to evaluate sleeping quality. The signals were combined with data mining technique to develop a basic sleeping quality evaluation system. In 168 days, 36 adults were invited to attend our experiment. We obtained their sleeping data and evaluated their sleeping quality. Finally, the accuracy of this evaluation system had reached 87.5%. With the development of mobile technology, mobile devices have brought a lot of convenience to our live. People use many applications of mobile devices to do social behaviors, watch videos and play mobile games. Mobile devices do not only gradually affect our bedtime activities, but also has effect on our sleeping quality. This study explored the effect of bedtime activities on the sleeping quality and brainwave. Using a mobile device to do activities, such as gaming, watching videos, or chatting on the Internet before sleeping, would increase the proportion of high amplitude in each band(α, β, θ and δ), and then lead the quality of sleeping downward. Among these activities, watching the video had the hugest effect on sleeping quality. Furthermore, surfing the Internet and gaming before sleeping would affect the sleeping quality of the female participants. In addition, watching videos had more effect on males’ sleeping quality.
