The broader impact/commercial potential of this I-Corps project is in resolving the long-standing graphical access problem for millions of blind and visually-impaired (BVI) people. Lack of access to these substantial informational components of daily life represents one of the biggest challenges to the independence and productivity of BVI individuals. This project addresses this vexing accessibility issue through a viable information access solution built on commercial, low-cost touchscreen-based smart computing devices such as smartphones and tablets. The solution will assist BVI people by potentially providing dynamic access to digital school books and test materials, graphics in vocational settings, digital maps, and graphical contents of printed materials. The broader impact of this project is that it will promote empowerment of BVI individuals by supporting increased educational advancement, vocational opportunities, enhanced quality of life, and overall greater independence.This I-Corp project will explore the commercial potential and market fit for a touchscreen-based graphics screen reader. This solution will allow blind people to freely explore and access graphical information via vibration and auditory feedback on a smartphone or tablet. Through a battery of usability, psychophysical, and technical experiments, the technology has been shown to be effective compared to existing solutions and is accurate in conveying informative graphical materials such as graphs, shapes, patterns, and indoor maps. The focus of the proposed I-Corp project is to understand the commercial fit and usability of the solution in meeting end-user needs and problems.

这个I-Corps项目更广泛的影响/商业潜力是解决数百万盲人和视力受损（BVI）人群长期存在的图形访问问题。无法获得日常生活中这些重要的信息是英属维尔京群岛人独立和生产力面临的最大挑战之一。这个项目通过一个可行的信息访问解决方案解决了这个令人烦恼的可访问性问题，该解决方案建立在基于商业、低成本触摸屏的智能计算设备（如智能手机和平板电脑）上。该解决方案将帮助英属维尔京群岛人，可能提供动态访问数字教科书和考试材料，职业环境中的图形，数字地图和印刷材料的图形内容。 这个项目的更广泛的影响是，它将通过支持增加教育进步，职业机会，提高生活质量和整体更大的独立性来促进BVI个人的赋权。这个I-Corp项目将探索基于触摸屏的图形屏幕阅读器的商业潜力和市场适合度。该解决方案将允许盲人通过智能手机或平板电脑上的振动和听觉反馈自由探索和访问图形信息。通过一系列的可用性、心理物理和技术实验，该技术已被证明是有效的，与现有的解决方案相比，它可以准确地传达信息丰富的图形材料，如图形、形状、图案和室内地图。拟议的I-Corp项目的重点是了解解决方案在满足最终用户需求和问题方面的商业适合性和可用性。
