A device or software application designed for use without visual feedback offers accessibility to individuals with visual impairments. An example is a physical device with tactile buttons and an auditory output, or a screen reader-compatible software application that announces calculations audibly. These tools allow users to perform mathematical operations independently.
Empowering visually impaired individuals to perform calculations without reliance on sighted assistance is crucial for promoting independence and inclusion in educational, professional, and everyday settings. Historically, specialized devices were necessary, but advancements in technology have integrated this functionality into more commonplace software and hardware. This accessibility feature enhances equal opportunities and enables greater participation in STEM fields and other areas requiring numerical proficiency.
