近年來智慧型手機對大眾的影響甚鉅,不僅手機持有率上大幅上升,民眾使用智慧型手機的時間也大幅增加,日常生活中「低頭族」隨處可見。然而多數人使用智慧型手機的不良姿勢容易導致肩、頸和背部相關的痠痛與疾病。因此本研究藉由在頭部與背部放置數個慣性感測器,藉以量測胸椎和頸椎角度。同時也提出了 “姿勢監測演算法”,利用慣性感測器量取之角度監測使用者的姿勢。並希望未來能將其實際應用在手機上,達到監測不良姿勢與提醒的效用。
本篇研究設計了兩個實驗,首先針對手機角度和頸椎、胸椎角度關係進行探討。並發現針對個人使用者,手機傾斜角度對於頸椎並沒有相關性。在第二個實驗中,除了驗證演算法之外,也對不同的手機位置如何影響使用者姿勢進行討論。最後實驗發現手機的高度與傾斜角度對於人體姿勢都有相關性。除此之外,也發現在站立、坐著無桌子和坐在桌前之中,坐在桌前使用手機能大幅的減少頸椎彎曲角度。最後也發現頸椎角度和胸椎角度有相關性,代表當使用智慧型手機而造成低頭時,也容易造成駝背。
In recent decade, smartphone has a great influence on human’s life. Smartphone ownership grows at a skyrocketing speed, and people spending more and more time on using smartphone every day. But the poor posture and overusing of smartphone can easily cause neck pain. There’s also a new term called ‘text neck’, which means bending neck forward for a long period of time or too frequently. There’s several study shows that neck flexion leads to neck pain. In this paper, we propose a wearable device and a posture monitoring algorithm, based on the inertial measurement units mounted on top of the head and upper back. By this, we can monitor user’s neck and spine posture. In the future, we look forward to implement the system on smartphone, in order to monitor posture in daily life.
In the first experiment, we will discuss about the relationship between phone tilting angle and neck and spine posture. Unexpectedly, we found out that phone tilting angle has no correlation with single user’s neck angle and thoracic angle. In the next experiment, we evaluate our algorithm between IMU and Vicon data. Moreover, we discover some important conclusions. For example, the height of the smartphone is the major factor affecting human posture. Otherwise, neck angle has relation with thoracic angle, which means bending head forward can affect thoracic angle.
