Literature Review On Body Motion Analysis

CHAPTER 2

LITERATURE REVIEW

2.1 Introduction

The case study is the motion capture analysis in three dimension (3D) that used for individually coaching aid. Hence, the literature review was explained by three main topics. The first topic is a review on motion capture analysis of human body from the previous works or researches that related with the case study. Some example of any available developed software or human body motion analysis that almost similar with the case study will be compared in this topic. Second main topic is about engineering mechanics of human motion analysis. In this topic, the human body’s motion were describes and relates referring on the kinetics, kinematics, dynamics, and biomechanics analysis. Another sub

Kinematics also could be describe as the movement regardless of the forces that generates movement. Therefore, velocity and acceleration are excluded in the discussion kinematic geometry. While Kinetics is defines as the relationship between the forces that act on a body and the motion of the body. A particle is a body whose size does not affect its response to the forces that act on it.

The entire kinematic system could be illustrated by modelling the human body as a system with segment as shown in Figure 2.4 and determining the kinematics of individual body segments. This segment represent as rigid bodies of the human body model in the study. Geometry of the kinematics that can be known is the velocity and the angular acceleration or the centre of body mass, angular velocity and angular acceleration of the body itself, and all the relatives for fixed or inertial frame

Scientists and professionals implemented the biomechanics principles in a lot of fields, research, and problems that related to human health and performance analysis. Analysis of human motion may be either quantitative or qualitative. Quantitative implies the numbers are involved while qualitative refers to a description of quality regardless the use of numbers. Both quantitative and qualitative descriptions play important roles in the biomechanics analysis of human motion.

2.3.4 MATLAB Software

MATLAB stands for Matrix Laboratory. It is an interactive program or computing language that focuses on the array of numbers to process or illustrated the data. Various data values are collectively and known by the single name and organized into rows and columns. The Math Works Incorporated developed the software with a variety of applications. MATLAB programs execute MATLAB programming language. It provides a library of functions that have been assigned to make technical programming tasks easier and more
