Area of Science:

  • Ergonomics
  • Human-Computer Interaction
  • Occupational Health

Background:

  • Traditional workstation design often overlooks individual anthropometric variations, potentially leading to discomfort and reduced productivity.
  • Optimizing the sitting working environment is crucial for minimizing physical strain and fatigue during computer-based tasks.

Purpose of the Study:

  • To develop and present an ergonomic approach to designing and modeling sitting workstations using computer programs.
  • To minimize energy consumption and fatigue by optimizing regular posture during computer work.

Main Methods:

  • Development of a specialized computer program that utilizes worker data (work type, sex, height) to determine optimal ergonomic parameters.
  • Computer visualization and 3D anthropometric analysis to calculate spinal curvature, arm/leg manipulation angles, and body space dimensions.
  • Assessment of optimal workstation and machine dimensions based on 3D anthropometric movement analysis for various worker heights (160 cm, 175 cm, 190 cm).

Main Results:

  • Calculated optimal ergonomic parameters for sitting workstations, including spinal angles and manipulation ranges for arms and legs.
  • Established dimensions for manipulative body space through 3D anthropometric analysis of movement.
  • Defined optimal machine and working space dimensions aligned with worker anthropometry to enhance utilization.

Conclusions:

  • The developed computer program and ergonomic modeling effectively determine optimal sitting workstation parameters.
  • Computer-aided ergonomic design significantly contributes to reducing physical fatigue and energy expenditure for computer users.
  • Integrating anthropometric data into workstation design is essential for creating efficient and comfortable working environments.
