Theory

 

The normal tendency of the diameter of the body increases from standing height to squatting height.

While designing any workstation where posture is required proper distance must be maintain for the body to fit in the given space.

   

 Procedure

 
The subject is asked to take squatting posture and perform different activities like arm stretching. Measurements can be done using photographic methods, using still photography and filming the whole body from different

angles how people used to perform their daily activity on the work surface. Analysis of photographic records of an activity against a suitable grid and anthropometric rod set also can be used.
 

   

Direct and indirect body measuring

Step by step procedure

Direct method

Measuring dimensions: Technique   

 
Direct body measuring instruments mostly used are: A common set of anthropometric instruments and anthropometric board with grid marks. A physical environment is simulated where the subject is asked to perform their activities and different measurement is taken.

The study can be done with the photographic record of a real work situation or in a laboratory with simulated work condition where the subject is asked to perform their tasks with comfortable squatting postures.

 

 

Indirect method

 

Indirect measurements may be taken through photographic methods, using still photography and filming the above mentioned experiments with the subject against a marked grid background, or superimposition of a grid on the photographed human body. To guard against parallax errors - problems where the actual dimensions may change care must be taken. For dynamic measurements, subjects are asked to perform the intended tasks in actual and or simulate situations and the relevant measurements are taken.

   
 

About experiment

 
 

This experiment aims at understanding the relevant space or distance required to perform different task in squatting posture. The experiment gives a feeling of real experiment to perform task in actual and or simulate situations
