Implementation of Chart Creation Functionality in Voice-Based Report Generator for the Visually Impaired

Being able to communicate information is important in the information society, and data visualization is an important way to do so, but there are limitations to software accessibility for the visually impaired. For the visually impaired who have difficulty creating charts, which are essential for information transfer and understanding, we implemented a voice report generator supporting various chart drawing. The system allows users to say the title, type, data, and labels of a chart, and then generates a chart based on this information. The system supports a variety of plot types, has a simple user interface, and can be operated using a Bluetooth remote control. We conducted an experiment to evaluate the usability of this system and found that it is a convenient and efficient system for generating reports without much difficulty for visually impaired people.
