Design and Realization of an Electromagnetic Guiding System for Blind Running Athletes.

Pieralisi M, Petrini V, Di Mattia V, Manfredi G, De Leo A, Scalise L, Russo P, Cerri G - Sensors (Basel) (2015)

Bottom Line: An example is represented by blind runners who need to be physically linked to a sighted guide by means of non-stretchable tethers during races; with consequent limitations in terms of performance and independence.The system consists of: (1) a mobile unit, which is placed before the runner and generates two "electromagnetic walls" delimiting the way; (2) a receiving unit (worn by the athlete) that provides vibro-tactile warnings every time the user is going outside the safe area so as to encourage him to move toward the central position.The feasibility and the utility of the system proposed are demonstrated by means of tests carried out thanks to the collaboration of a blind volunteer.

ABSTRACT
Nowadays the technologies aimed at improving the quality of life of people affected by visual diseases are quite common; e.g., devices to support walking or reading. Surprisingly, there is a lack of innovative technologies aimed at helping visually impaired athletes during physical activities. An example is represented by blind runners who need to be physically linked to a sighted guide by means of non-stretchable tethers during races; with consequent limitations in terms of performance and independence. This paper wants to investigate the possibility of realizing a system able to guide blind runners along a complex path, paving the way for the realization of an innovative device designed to improve their independence during training or competitions. The system consists of: (1) a mobile unit, which is placed before the runner and generates two "electromagnetic walls" delimiting the way; (2) a receiving unit (worn by the athlete) that provides vibro-tactile warnings every time the user is going outside the safe area so as to encourage him to move toward the central position. The feasibility and the utility of the system proposed are demonstrated by means of tests carried out thanks to the collaboration of a blind volunteer.

sensors-15-16466-f001: Schematic representation of the guiding system: two transmitting antennas, set on a mobile unit, generate two EM walls delimiting a virtual hallway that can guide the running athlete, properly equipped with the receiving system, along whatever paths.

Mentions: Therefore, as Figure 1 shows, the idea has been to equip a vehicle (that is depicted as a car, but it might be a bike or generally a mobile unit) with two transmitting elements able to generate two radiation patterns shaped as narrow vertical fans (angular width < 10°) delimiting two invisible ‘EM walls’ that confine the runner inside a secure hallway. In order to make sure that the athlete always remains inside the virtual hallway, two vibro-tactile warnings are generated each time he is getting close to one of the borderlines so as to encourage him to move back toward the central position, where no more warnings are produced. In a few words, as the mobile unit goes forward, the runner may safely follow it along a desired path.
