Development of a Usability Metric for Reading Displays in High Ambient Lighting Conditions

Predicting the readability of a display in harsh lighting conditions requires knowledge of the ambient lighting levels and reflections to be taken into account in addition to the contrast ratio performance of the display. The University of Abertay through the ENDSENSE project has developed a spreadsheet which can yield the JND (Just Noticeable Difference) usability metric for displays in different lighting conditions. This spreadsheet is available for download by signing in here.

For further information on the application of the JND spreadsheet to your display system, please contact Colin Cartwright at the University of Abertay.

Reading Displays in High Ambient Lighting Conditions – Development of a Usability Metric

The UK Displays and Lighting Network are hosting an event to showcase the DTI Funded project ENDSENSE on Thursday 29 March 2007 at Bletchley Park, Milton Keynes. The aim of the project is to develop display systems that can respond to the environment to enhance display viewability. Modelling of the end-user requirements and the internal display structure are being used to assess the performance of demonstrator displays in different illumination conditions.

International Display Workshop '06

Project partner presents paper at major international display conference, much interest was generated in this display usability metric that is being developed by Abertay University.  Further to this, a one day workshop will be held at MCE Newmarket on 29^th March 2007, see the UKDN website for further details
