dc.description.abstract | Some people with severe disabilities are con ned in a state in which communication is
virtually impossible, being reduced to communicating with their eyes or using sophisticated systems that
translate thoughts into words. The EyeTrackers and Brain-Computer Interfaces (BCIs) are suitable systems
for those people but their main drawback is their cost. More affordable devices are capable of detecting
voluntary blinks and translating them into a binary signal that allows the selection, for example, of an
ideogram on a communication board.We tested four different systems based on infrared, bioelectrical signals
(Electro-Oculography (EOG) and Electro-Encephalography (EEG)), and video processing. The experiments
were performed by people with/without disabilities and analyzed the systems' performances, usability, and
method of voluntary blinking (long blinks or sequence of two short blinks). The best accuracy (99.3%) was
obtained using Infrared-Oculography (IR-OG) and the worst with the EEG headset (85.9%) and there was a
statistical in uence of the technology on accuracy. Regarding the method of voluntary blinking, the use of
long or double blinks had no statistical in uence on accuracy, excluding EOG, and the time taken to perform
double blinks was shorter, resulting in a potentially much faster interface. People with disabilities obtained
similar values but with greater variability. The preferred technology and blinking methods were Video-
Oculography (VOG) and long blinks, respectively. The several Open-Source Hardware (OSHW) devices
have been developed and a new algorithm for detecting voluntary blinks has also been proposed, which
outperforms most of the published papers in the reviewed literature. | es |
