睡眠，對於人類來說是一天當中很重要的一件事情，只有充分且適當的睡眠才能讓身體獲得適當的休息並補充再活動的能量。不過越來越多的人因工作壓力或是健康狀況異常等因素漸漸的影響到自我的睡眠品質，更嚴重者將會造成睡眠障礙。
一直以來針對睡眠品質的評估，最常用的是藉由多項生理訊號儀器(PSG)量測出的結果來輔助進行，不過這類方法延伸出的是費用高且要有專業人員從旁協助執行的缺點，所以對於居家的睡眠品質改善並不適合。因此本論文提出一種可讓使用者在熟悉的環境下進行睡眠監測的分析系統，並期望透過系統量測出的訊號來協助睡眠品質的評估。
基於睡眠的特徵當中身體活動量的多寡與可能的長時間靜止是一種可用來評估睡眠狀態的方式。故本論文將開發一種非接觸式的可攜式頭部移動感測裝置來協助睡眠品質之分析，系統以內建壓力感測器所製作的頭部活動感測織布來收集受測者睡眠時的頭部活動訊號，並利用各時點壓力值斜率的簡易移動平均(SMA)搭配所設計的睡眠分期判斷規則來進行各睡眠階段的辨別，讓使用者或是醫生可以藉由本論文所開發的睡眠分期分析程式來了解自我或受測者的睡眠分佈狀況。
本系統中所提供的睡眠品質指標與評分只是要讓受測者了解自我睡眠品質的好壞程度，並不是要取代醫學標準的多項生理監測儀器(PSG)。期望透過這樣的系統能夠達成初期的建議，當受測者睡眠有出現一定程度的睡眠障礙趨勢，再到醫院做進一步的完整分析治療。

關鍵詞：睡眠、睡眠障礙、睡眠分期、壓力感測器、簡易移動平均

Sleep is a very important part of the day for humans. Only adequate and proper sleep can give the body proper rest and supplement the energy of reactivation. However, more and more people are gradually affecting their own sleep quality due to work stress or abnormal health conditions. More serious will cause sleep disorders

The evaluation of sleep quality has been performed most often through the measurement of results from PSG. However, this type of method extends to the disadvantage of high costs and the need for professionals to assist in their implementation. So, it's not suitable for improving the quality of sleep at home. Therefore, this paper proposes an analysis system that allows users to perform sleep monitoring in a familiar environment and we hope to assist in the evaluation of sleep quality through systematically measured signals.

The amount of physical activity and possible prolonged quiescence in sleep-based features is a way to evaluate sleep status. Therefore, this paper will develop a non-contact portable head movement sensing device to assist in the analysis of sleep quality. The system collects the head activity signal of the subject during sleep with a head activity sensing woven cloth made by a built-in pressure sensor. And use the simple moving average (SMA) of the slope of pressure value at each time point to match the designed sleep stage judgment rules to identify each sleep stage. The user or doctor can use the sleep stage analysis program developed in this paper to understand the distribution of sleep of the subject.

The sleep quality indexes and scores provided in this system are only for the subjects to understand their sleep quality and are not intended to replace the medical standard of PSG. It is hoped that the initial recommendations can be reached through such a system. When subjects have a certain degree of sleep disturbance, they go to the hospital for further analysis.
