Abstract
Persons with visual impairments have difficulties to work with graphical computer interface, such as Windows icons. Also they do not have access to objects of cultural and historical heritage such as paintings, tapestries, icons, etc. The chapter presents an approach for providing visual Braille services by 3D digitization of planar or spatial objects using a graphical Braille display and/or tactile graphical tiles, supplemented with Braille annotations. A solution involving 3D touch by tactile reading of exhibits in a version accessible and affordable to visual impaired people is presented. Different existing devices, called Braille displays are described. Our technology for graphical Braille display is on the base of linear electromagnetic micro drives is shown. The presented ‘InterCriteria’ decision making approach is based on two fundamental concepts: intuitionistic fuzzy sets and index matrices. A comparative analysis of hybrid electromagnetic systems on the base of InterCriteria Analysis approach is given.
