Evaluating Barten image metric for predicting character recognition in people with low vision

Kimberly A. Schoessow, OTD, OTR/L, et al.

Displays on electronic devices such as blood pressure monitors and cellular telephones are often hard for veterans with low vision to see. These devices often have small, low-contrast displays. This study examined a formula (Barten square root integral) that predicted whether people with low vision could read numbers on a screen. The next step is to determine whether the formula carries over to use in actual electronics. This information may help manufacturers make devices that are easier for people with low vision to use. It may also help people with low vision choose appropriate electronic devices.
