Smart pose

Abstract

With the widespread use of smartphones, users tend to use their smartphones for a long period of time with unhealthy postures, bending forward their upper body including the neck. If users keep such an unhealthy posture for a long time, their neck and back muscles get chronically strained, which might cause diseases such as cervical myalgia. To prevent these diseases, we propose a new methodology to monitor the posture of smartphone users with built-in sensors. The proposed mechanism estimates a value representing user postures like head/neck tilt angle by analyzing sensor data from a front-faced camera, 3-axis accelerometer, and orientation sensor. It then informs the user if the estimated value is maintained within the abnormal range over a pre-defined time.

Understanding Face and Eye Visibility in Front-Facing Cameras of Smartphones used in the Wild

“…Yoo et al proposed capturing the user's facial expressions through the front-facing camera for lifelogging applications [50]. EyeProtector and SmartPose leveraged users' face size in the front-facing camera view to warn users if they were too close to the screen [22,35]. There is also a large body of work about authentication via face recognition on mobile devices [40], such as FaceID.…”

Smartphone Based Cervical Spine Stress Prevention

“…The study was comprehensive but lacked a proper notification or warning mechanism [8]. Another study by Hosub Lee et al used an orientation sensor and the front camera of a smartphone to monitor the posture of the human body [9]. The drawback lied in the usage of two internal sensors of the smartphone-the triaxial Accelerometer and Magnetic Sensor (compass) to get [11].…”

“…Many of the applications, for example, Smart Pose, proposed in a past research paper, warns the user only momentarily; however, datum is not collected or reported over the day, week, or months [9]. Spined stores all the data of the posture in a local SQLite Database that is created when the app is first installed.…”

Neck posture monitoring system based on image detection and smartphone sensors using the prolonged usage classification concept

“…Nonetheless, these proposals did not provide accurate measurements of the neck movement or angle. Smart Pose is one of the latest studies attempting to find a preventive solution for this syndrome. The authors of Smart Pose developed a system based on the sensors embedded in modern smartphones.…”
