Accessibility Features

  • Support for braille. Students who are blind can read and write equations using the two mathematical braille codes used in the United States: Nemeth and Unified English Braille (UEB).
  • Accessible graphs. Students who are blind can create their own graphs in real time and determine the shape of a graph through audio trace. The pitch of the tone increases or decreases depending on the shape of the wave or graph. Students can then emboss their graphs and share print or braille versions with classmates and teachers.
  • Support for screen readers. Fully supporting keyboard navigation, the calculators communicate with screen readers, which voice additional cues to indicate a student’s location within an expression or within a graph (numerator or denominator, superscript or subscript, baseline, points on the graph, etc.). Paired with a refreshable braille display, these features offer students who use braille the same opportunity as their peers to access an online calculator.
  • Colors that have sufficient contrast. The calculators provide support for students who have low vision or students who have difficulty with visual perceptual skills.
  • Adjustable font-size settings. The calculators allow students to adjust font size if they prefer larger print.

The Smarter Balanced Desmos calculators is also compliant with the latest web accessibility standards.
