Visibility Analysis

Error Analysis consultants have an in-depth understanding of the processes that enable us as humans to see our world.  This understanding enables us to design for function, visibility, and comfort, as well as analyze the perceptual-cognitive factors contributing to various injury incidents.       

We are often asked to analyze visibility in:

  • Walking
  • Working
  • Driving
  • Operating industrial and recreational equipment
  • Using a variety of consumer products and technological systems

A sample of our publications include:
