Mathematical learning from digital libraries and the web is a challenging problem for people with visual impairments and blindness. In this paper, we focus on developing the mathematical learning skills of braille users with a new assistive technology developed to retrieve semantically mathematical information from the web. This kind of research is still in the study phase. This paper presents an overview of assistive technologies for braille users followed by a description of the proposed system, which works in four phases. In the first phase, we translate a query math formula in braille into MathML code, and then we extract the structural and semantic meaning from the MathML expressions using multilevel presentation. In the classification phase, we choose a multilevel similarity measure based on K-Nearest Neighbors to evaluate the relevance between expressions. Finally, the query result is converted to braille math expressions. Experiments based on our database show that the new system provides more efficient results in responding to user queries.

Abstract-Math search or mathematical expression retrieval has become a challenging task. Mathematical expressions are very complex, they are highly symbolic, and they have a semantic meaning that we should respect. In this paper, we propose a similarity search method for mathematical expression based on a multilevel representation of expressions and a multilevel search. We used the K-Nearest Neighbors with three types of distances to evaluate relevance between expressions. In the experimental level, the proposed system significantly outperforms statistical algorithms.

“…Adaptive technology for VIP students is usually applied through two approaches: the static [10], [11], which basically uses the Braille code (sometimes an extended Braille code) for translating concepts, and the dynamic [12], [13], which has the audio as a fundamental tool for translating concepts.…”

The learning of geometric concepts by Visually Impaired People (VIP) is a huge challenge. This paper presents a new dynamic computer-based environment for the learning of geometric concepts through adaptive technology. A case study on learning of geometric concepts in VIP classrooms using the proposed environment is detailed. Several experiments carried out with signed subjects (control group) and VIP subjects (experimental group) using the proposed method is also discussed. The results of this case study have shown that: i. the learning of geometric concepts by the VIP students was done through a peremptory and autonomous way; ii. the VIP students improved their ability to learn, retain and apply obtained concepts in other contexts; iii. the environment innovated the VIP geometry learning and increased their logical reasoning iv. the continuous use of the environment have enabled them to improve their spatial positioning and motions; v. the environment exhibited a superior performance than the classical geometry teaching in VIP classrooms. The main result of the experiments is that VIP students required (in average) only 20% of the time that was required in classical classes for solve correctly all proposed exercises.
