A simple procedure for using vision impairment simulators to assess the visual clarity of product features

Abstract

Capability loss simulators give designers a brief experience of some of the functional effects of capability loss, thus helping them to understand capability loss better. Wearable simulators, such as vision simulator glasses, can also be worn while using products and prototypes to help identify usability problems. However, this process can be confusing. This paper presents a simple procedure for using vision impairment simulators to assess the visual clarity of product features. The procedure provides clear results that are linked to the numbers of people in the population affected by the issues identified. It was tested with eight accessibility specialists and product developers. Results indicate that they can use this method effectively, and find it useful.
