GNIE is currently deployed at a local school for the blind where it is being used for middle school mathematics.
Braille blocks and other tactile tools are typical instruments used to teach math concepts to students with vision impairment.
Auditory graphing tools such as GNIE can serve as a useful supplement for teaching and learning math concepts.
Graph and Number line Input and Exploration (GNIE)
Graph literacy is an important skill to master for a variety of reasons, for instance in order to pursue a career in science, technology, engineering, or mathematics (STEM), but the problem with graphs is that they are visual in nature. This puts people who have vision impairment at a disadvantage because they have difficulty accessing that information. Auditory graphing systems that use sound to convey information are a strategy for addressing this issue. Auditory graphs are capable of delivering graphing information in real-time, are easy to customize, more portable, and, as a teaching medium, can be accessed by low-vision, blind, or sighted users. However, they have largely not been evaluated in real-world classrooms despite their potential benefits in this context. Consequently, not much is known about the circumstances which allow for classroom adoption or the costs/benefits and impact of introducing this technology.
Our goal is to address those issues and provide an in-depth analysis on the impact of introducing a new assistive technology in a visually impaired classroom.
