Featureless control panels and embedded small visual displays (SVDs) are becoming more and more common on a wide range of household and electronic devices, making it increasingly difficult for people who are blind or visually impaired to find products that they can use independently. Older products typically used easier-to-feel control buttons and knobs that made settings easier to change and confirm. Newer products, however, often use touch screens and non-tactile controls as well as SVDs that display critical information.
