This page contains information about various calculator options for people who are blind or have low vision. This information will help you make an informed decision about the right calculator option for your needs.
It is important to note that not all calculators have all the functions to complete all requirements of secondary or tertiary level maths.
Stand alone or desktop options
Vision Australia’s Equipment Solutions sells a number of basic stand alone talking calculators. The desktop talking calculator with headphone jack is recommended for students because it has an easy to use layout and can be used privately. Functions include addition, subtraction, multiplication, division, percentage and memory.
Students with low vision may be able to successfully access a calculator from retail outlets in conjunction with a hand held magnifier or video magnifier. Please note that some older video magnifiers cannot display the calculator’s LCD display when they are in black and white mode.
Large Print and Talking – this product is available through Vision Australia’s Equipment Solutions. It should be noted that this does not follow the conventional order of operation found in current mainstream scientific calculators used in classrooms.
For example, mainstream scientific calculators require you to enter the square root button first and then the number you wish to square root. The large print talking scientific calculator requires you to press the number first and then the square root button. This may disadvantage some students in a classroom when they are trying to follow a teacher’s instructions.
