Research Methodology of the Parameters of Tactile Perception of Relief Forms by the Blind and Low Vision People

Abstract

Currently, more than 500 million people are persons with disabilities, and people with visual disabilities occupy a special place among them. In modern practice, depending on the degree of visual impairment, division into “blind” and “low vision” is used. Experts from many countries are looking for effective programs to restore the health of people with vision problems. In Russia, the system of teaching blind and low vision people is an integral part of the educational process and is based on the method of compensation of visual perception by tactile one. The peak of studies of tactile perception fell on the second half of the twentieth century; however, most of the work is currently outdated. Currently, the study of the process of tactile perception is very relevant. This is primarily due to the change in attitude towards people with vision problems. Secondly, there is the possibility of using innovative technologies and equipment. In the paper the method of payment in traditional and modern areas of typhlopedagogy is considered. The author of the paper proposes an alternative developmental approach aimed at improving the tactile sensitivity of blind and low vision people under the condition of cognitive perception. It is noted that in the process of perception the forms are characterized by qualitative and quantitative parameters. In accordance with the developing approach, the method of studying the parameters of tactile perception is proposed. The most applicable parameters are: a step, a size, geometry, an orientation, a degree of volume. A plan for the study was developed, which includes the stages: the choice of tactile perception parameters, the development and production of samples for the study, the choice of the research method, the development of the questionnaire, the choice of the subjects, the experiment and the fixation of the results, the analysis of the results.
