Modern international research has focused its interest on better understanding the brain functions of individuals with visual impairments. An indicative example is the study of hand preference and its functional consequences, which can reveal how genetic variations affect the cognitive abilities of individuals with visual impairments.

Interest has also been drawn to the impact of the qualitative characteristics of hand preference, such as hand and finger movements, on reading and spelling through the Braille code.

This book is aimed at both educators and students training to teach individuals with severe visual impairments, aspiring to present both the latest literature review and useful techniques on writing and reading through the Braille code, which are applicable in the daily educational practice of students with visual impairments.
