Learning Math for Visually Impaired Users
نویسندگان
چکیده
Writing and reading formulas or perceiving the graph of a function stand in the way of a blind student for an efficient and complete study of Math. We propose an architecture made by different components that allows to a blind user to face the study of the mathematics in total autonomy. The system allows the formula editing, and the formula exploration. In case of the formula represents a 2D function, the system innovatively supports the haptic and audio exploration of the corresponding graph through a very cheap IO device. The article describes the system architecture and the test results.

Case Study: Providing Enhanced Content Accessibility to Images for Visually Impaired Users
Several web sites, such as e-learning platforms, online museums, etc. are available via the web, and allow users and visitors to learn at a distance. Several e-learning platforms or in general informative web sites (such as museum web sites) have also started to make their web site “accessible”, making them more navigable for (visually) impaired users. However, accessibility in the current conc...
متن کاملAn Investigation into Virtual Objects Learning By using Haptic Interface for Visually Impaired Children
It is well known that visually impaired children have limited opportunities in learning new things compared to normal sighted children as visually impaired children do not have one of the important senses of human being. Computer simulated virtual reality environment can provide better opportunities for visually impaired children especially in learning the shapes of new objects. An application ...
متن کاملAccessibility of E-Cloud: An Algorithm for Implementing Interface Specification for Visually Impaired
This paper describes the architecture of cloud service and technologies for implementing accessible services for visually impaired (VI) users. The cloud computing emerges as a natural platform for learning. The Educational Cloud (ECloud) computing provide terminals with powerful e-learning resources. However, these e-learning resources are not accessible for VI users. The paper discusses the cl...
متن کاملClassification of Mathematical Expressions for Visually Impaired People
Visually impaired people, face many problems to communicate and to study electronical scientific documents especially those containing mathematics expressions. To provide solutions in this topic, we propose an assistive system to help blind people to categorize mathematical formulas from electronical documents. The system acts on four steps: first the translation of query math formula into Pres...
متن کاملi-Math: Automatic math reader for Thai blind and visually impaired students
We propose an automatic math expressions reading system, called KANID. KANID is an educational tool, for blind and visually impaired (VI) students, to facilitate access to math materials. Although blind and VI students can access math documents/materials via many channels, e.g., human reader, math Braille codes, and audio (talking) books, these channels have limited availability. KANID was desi...
