Making the world more visible

APPS & BOOKS

CROMOCON APPs

CROMOCON established the ‘5 Factors’ software that is essential for VIP perception. The three APPs use it to check the world is visible for 93% of VIPs.

We made them, checked them and tested them!

 These factors built the unique APPs’ software algorithm, with over 25 years of research and testing with visually impaired people (VIP).  They are proven critical variables of visibility.

Adjust any of the 5 factors in the APP and it will check whether an object or element in a building is VISIBLE. Our customers call it a’no-brainer’ to success!

1  VISUAL ABILITY – the VA Group is fixed default of 93% of VIPs
2. CONTRAST* – Calculated between object LRV & Background LRV
3. LUX LEVEL – Lux Meter or similar device for light assessment
4. DIMENSION – Visible width of object, but must be the minimum
5. DISTANCE – Measured distance from a critical viewing point of the object

  • The 3 CROMOCON APPs are unique pieces of software
  • We know the level of CONTRAST VIPs need to navigate environments
  • The APPs are currently available for mobile platforms IOS and ANDROID
  • CONTRAST* is derived from the difference between adjacent surface LRVs
  • Get the CONTRAST right with measured LRVs – get visibility right!

2   CROMOCON APP

“It’s so easy to be sure of CONTRAST and visibility”

  • Amazing original APP software available from iTunes and GooglePlay!
  • A fast and easy APP, a valuable way of calculating the visibility
  • The VA Level V4 – V9 (93% of VIPs) a fixed default cannot be adjusted
  • The software adjusts other 4 factors for successful specification of VISIBLE
  • Press NOT VISIBLE if displayed and select SUGGESTIONS to change a factor
  • The Dimension for example of a chair or column, or Distance are critical
  • But CONTRAST can be changed easily by raising the floor LRV or lowering a wall LRV

3   CROMOCON USA APP

“A great tool for getting LRV right, globally”

  • In the USA, CONTRAST guidance is calculated differently from UK/Europe
  • Professionals in the USA enter the LIGHT of the two LRVs first
  • Then the DARK LRV second – the CONTRAST is then calculated
  • The CROMOCON USA/International APP works the CONTRAST out
  • The figure is entered into the CROMOCON VISIBILITY CALCULATOR 
  • Calculated with remaining bits of data – Lux Level, Dimension and Distance
  • The software assesses if objects are VISIBLE or NOT VISIBLE  for 93% of VIPs 
  • Press NOT VISIBLE if displayed and see SUGGESTIONS for adjustments
  • A higher CONTRAST should usually give a successful VISIBLE result
  • Check Distance as 3 metres away is critical
