Formal and physical sciences such as mathematics, statistics, physics etc. are very visual in their nature. We observe several objects concurrently and put them into suitable positions in space or a plane, which helps us understand the relationship between them better and enables us to work with them more effectively. Many mathematical algorithms are based on visual manipulation with objects, e.g. graph theory, linear algebra and calculus.
How can blind students use a given mathematical algorithm in view of the fact that they work in linear way, which means that they can only follow a very limited amount of information at the same time? It is certainly possible for a blind student to proceed the algorithm in the same or similar manner as his/her sighted peers do but very often he/she is not sufficiently effective. For people with low vision, it is not easy to find and then work with objects in space: this requires much more time and energy in comparison with the sighted. A suitable adaptation of the algorithm which respects the linear way of processing the information can often be helpful.
On these web sites we present:
- general hints to follow in such a situation and what to focus on;
- demonstrate our obtained knowledge and experience on our own proposals of selected algorithms' adaptations;
- want to discuss the algorithms' adaptation and let the websites' users to evaluate our methods or to propose more possible solutions.
