Abstract
The aim of this paper is to present the electromagnetic (EM) technology as possible assistive technology for the mobility tasks of visually impaired subjects. The paper will present their characteristics, discussing pros and cons of their use with respect to the existing traditional technologies and electronic travel aids, in terms of performances, miniaturization and wearing comfort. In particular, two applications of EM technologies will be presented more in detail: a first example consists in the design and realization of a laboratory prototype of an EM system able to detect the presence of obstacles along the walking path of visually impaired users and hence to assist them during their mobility tasks, possibly allowing them to walk safely and independently. The second example is the theoretical and experimental study of feasibility of an EM system specifically addressed to visually impaired runners. In conclusion, some hints for discussion will be presented; the user interaction with the sensing system, the signal analysis and possible features extraction will be reviewed addressing issues requiring a multidisciplinary approach.
