Quantifying the proportion of the population who are unable to use a product is extremely persuasive to deliver inclusively designed solutions to market. This paper presents a new method for assessing artwork that is typically viewed at a hand-held distance, such as mobile phone icons. The assessment is performed by mounting the artwork on a wall, and then simulating reduced visual ability by viewing the artwork from further away than you normally would (i.e. walking backwards). Finally, exclusion is quantified by comparing the artwork being assessed against a vision test chart. This new method is able to capture and justify the sort of minor improvements that can really make a difference for people with age-related long sightedness, in a commercially relevant context.
