A Review of Accelerometer Sensor and Gyroscope Sensor in IMU Sensors on Motion Capture

Abstract

IMU is electronic devices that used on specific body, angular rate and sometimes magnetic fields surround the body, use combination of accelerometer sensor and gyroscopes sensor, sometimes magnetometer to but IMU usually just using accelerometer and gyroscope sensor. IMU Sensor usually used on aircraft maneuver include Unmanned Aerial Vehicles (UAV) and space aircraft include landers and it's satellite. Accelerometer is an automatic tool for measuring acceleration, detecting and measuring vibration (vibration) and measuring acceleration due to the body (inclination). The accelerometer can be used to measure vibrations in cars, engines, buildings and security installations. Gyroscopes is device that mounted to a frame and can sensing an velocity of angular if that frame is rotate. There is some gyroscopes classes, depending on the operation physical and technology that involve.

“…An accelerometer is a sensor for accurately measuring applied acceleration [ 49 ]. Typically, an accelerometer uses three perpendicular axes, commonly referred to as x, y and z.…”

Generic Body Expression Recognition Based on Synthesis of Realistic Neutral Motion

“…At the same time, with the increasing proliferation and popularity of human skeletal capture devices i.e. Kinect [9], accelerometers-based [10], webcam-based [20], etc., researchers have also focused on the problem of recognition of actions based on skeleton analysis [21], [22]. And more recently, research community has shown interest in the recognition of expression based on body movements [23].…”

“…Nevertheless, if facial expression recognition was widely studied [6], [7], body expression recognition is still an emerging area. Furthermore, with the growth and easy access of devices that track 3-dimensional body, like the Kinect [8], [9] or accelerometer [10] based motion capture system, different applications will emerge based on body expression recognition. Our assumption is that many applications would benefit from the ability to understand human emotional state in order to provide more natural interaction, e.g.…”

Studi Literatur Human Activity Recognition (HAR) Menggunakan Sensor Inersia

“…Akselerometer menangkap informasi kecepatan pada sumbu x, y dan z (3-axis). Sedangkan giroskop digunakan untuk menangkap perubahan orientasi atau perubahan kecepatan rotasi yang disebut dengan roll untuk sumbu x, pitch untuk sumbu y, dan yaw untuk sumbu z [11]. Visualisasi rotasi pada masing-masing sumbu dapat dilihat pada Gambar 1.…”
