    • Documentation of analysis

RULA


Rapid Upper Limb Assessment

OWAS

 

Ovako Working Posture Analysing System

 

  • OWAS static posture analysis
  • OWAS static-dynamic posture analysis

These analyses are developed in collaborationwith TU Dresden, Professur für Arbeitswissenschaft: 

  • Visibility
  • RULA
  • OWAS
  • Bodyforce

Body force analyses

 

Methods of examination:

  • The montage-specific body force atlas
  • The DIN 33411-4/5 normative process
  • Taking the activity and human attributes into 

     account following the Schultetus Method

Visibility analyses

SIGHT ANALYSES


Optical displays are used in case of cockpits,

measurement tools, displays, consoles among

others.

 

Light conditions, visibility and display of information

all significantly affect the work performance and

comfort of users.

EYE, HEAD AND BODY MOTORICS

 

  • Eye target
  • Limits of eye movement
  • Stereoscopic sight
  • Eye positions: right, left, middle
  • Camera shade projection and focus for all eye positions

FIELD-OF-VISION ANALYSIS

 

  • Field of acuity
  • Optimal field of vision
  • Maximal field of vision
  • Field of colour vision

Optical displays

 

User-oriented parameters

 

  • Field of vision
  • Angle of view
  • Angle of perception
  • Eyeshot
  • Accommodation
  • Acuity
  • Position of the line of sight
 
Product-oriented parameters

 

DIGITAL DISPLAYS

 

  • Signal height
  • Signal width
  • Line thickness
  • Distance between signals
  • Line spacing

 

ANALOG DISPLAYS

 

  • Distance between lines on scale
  • Length of lines on scale
  • Length of scale
  • Parameters of numerical values
