Travel assistant for persons with visual disabilities

In the last years, significant efforts were made in order to improve the life quality, mobility and independence of persons with different physical impairments. Embedded microcomputer systems as well as intelligent software are used as building blocks for making dedicated systems which are meant to overcome the challenges caused by different kind of disabilities. Although an important percentage of persons suffer from visual disabilities there are not yet widespread solutions for this category of persons. This paper tries to evaluate the specific needs for such persons and offer pragmatic solutions based on the latest information and communication technologies (ICT).
