Understanding human motion involves detailed anatomical and spatial analysis. The Cartesian coordinate system is employed to standardize descriptions, with joint centers marked by numerical coordinates.
- STANDARDIZING DESCRIPTIONS OF HUMAN MOTION
- USED CARTESIAN COORDINATE SYSTEM
- HUMAN BODY JOINT CENTERS LABELED WITH NUMERICAL X / Y COORDIINATES
QUALITATIVE ANALYSIS
CONDUCTING THE ANALYSIS
1) IDENTIFY QUESTION / PROBLEM
2) MAKE DESICIONS
- VIEWING ANGLE
- VIEWING DISTANCE
- PERFORMER ATTIRE
- ENVIRONMENTAL MODIFICATIONS
- USE OF VIDEO
3) COLLECT OBSERVATIONS
- VISUAL
- AUDITORY
- FROM PERFORMER
- FROM OTHER ANALYSIS
4) INTERPRET OBSERVATIONS
5) COMMUNICATE WITH PERFORMER
REFINE QUESTION
6) END ANALYSIS
PLANNING
- WHAT QUESTION TO BE ANSWERED
- WHAT ANGLE / PERSPECTIVE SHOULD THE MOVEMENT VIEWED
- HOW MANY OBSERVATIONS SHOULD BE TAKEN
PREQUISITE KNOWLEDGE
- PURPOSE OF THE SKILL
- CAUSE OF PERFORMANCES ERROR
- HOW KNOWLEDGE CAN BE GAINED
DEFINITION
- ERECT STANDING POSITION WITH ALL BODY PARTS FACING FORWARD
- STARTING POINT FOR ALL BODY SEGMENT MOVEMENTS
REFERENCES AXIS
i) MEDIOLATERAL AXIS
- IMAGINARY LINE AROUND WHICH SAGITAL PLANE ROTATION OCCUR
ii) ANTEROPOSTERIOR AXIS
- IMAGINARY LINE AROUND WHICH FRONTAL PLANE ROTATION OCCUR
iii) LONGITUDINAL AXIS
- IMAGINARY LINE WHICH TRANSVERSE PLANE ROTATION OCCUR
