CBM346 Ergonomics Syllabus – Anna University Regulation 2021
COURSE OBJECTIVE
● To get exposed to principles of visual capabilities.
● To learn the mechanics of muscle physiology and significance of rest cycle.
● To learn spatial compatibility and the relation between control orders and control response.
● To know about the measurements and proportions of the human body.
● To be familiar with the mathematical models, analysis and design of biomedical devices using case studies.
UNIT I VISUAL AND AUDITORY ERGONOMICS
Process of seeing – visual capabilities – factors affecting visual acuity and contrast sensitivity – human factor aspects of hard copy text and computer screen text, factors in selecting graphic representations symbols, qualitative visual display – process of hearing – principles of auditory display. Measures for monitoring control & mitigation.
UNIT II MUSCLE PHYSIOLOGY
Muscle physiology – muscle metabolism – respiratory response – joint motion study – measure of physiological in-efficiency and energy consumption – work rest cycles – aspects of manual and posture study, material handling (MMH) Bio-mechanical recommended limits of MMH.
UNIT III CONTROLS AND DISPLAYS
Spatial compatibility and physical arrangement of displays and controls – Design of displays and controls – movement capability – rotary controls and rotor displays movement of displays orientation of the operator and movement relationships control orders and control responses – human limitations in tracking task
UNIT IV ANTHROPOMETRY
Anthropometry – anthropometric design principles – Physical work load and energy expenditure – work space envelope – factors in design of work space surfaces – principles of seat design – principles of control panel. ergonomic implications. Organization classification of human errors theories of accident causation-reducing accidents by altering behavior.
