Abstract
Successful communication is considered an essential component of the quality of care and safety of the patient
with Amyotrophic Lateral Sclerosis (ALS). Recent technology has provided alternative communication systems,
including the Eye-tracking technology, which enables interaction with others in the more advanced stages of the
disease. The aim of the study is to investigate patients' difficulties in using the eye tracker, their problem in ob-
taining the device and the clinical complications resulting from it. A “snowball sampling” method study was
conducted from April to September 2020 until sample saturation. The results of the study demonstrate the
countless difficulties in obtaining the eye- tracker, with long waiting times, which are not followed by adequate
training in its correct use. Among the consequences linked to the use of this device, the most frequent were nys-
tagmus (8.8%), onset of eyelid ptosis (16.2%) and the appearance of increased fatigue. 56.1% of the sample used
the eye tracker to surf the Internet whereas 9.1% used it to write e-mails. Overall, the use of the eye tracker led
to an improvement in overall quality of life (24%). In Conclusions, the Eye-tracking technology is a valuable de-
vice for Alternative Augmentative Communication (AAC) in ALS patients and can be used with good perfor-
mance, therefore the need for information, training and improvement on this topic is essential

1. Introduction
The incidence of Amyotrophic Lateral Sclerosis
(ALS) is about 1-3 cases per 100,000 inhabit-
ants per year and the relationship between
physical impairment and psychological condi-
tion is an important issue that involves a direct
correlation between severity of depression and
physical disability. In recent decades, the pro-
gress of biomedical technologies has led to
great benefits in the field of healthcare, with the
aim of improving the health of individuals and
offering alternative solutions to traumas and
various diseases. Among these, ALS patients
have always used computer media, including
computers, writing and digital language systems
to communicate with the outside world.
(Beukelman and Mirenda, 2014). Studies on the
mental evaluation of ALS patients have report-
ed complaints such as depression, anxiety, loss
of emotional control and alienation, as well as a
high risk of suicide in the early stages of the
disease (Cui et al., 2015). In the presence of this
debilitating neurodegenerative disease, the
