Eye-tracking based system for diagnosing deficits related to attention
VADET offers an innovative solution for diagnosing attentional deficits, by integrating an eye-tracking device with a software, which has been specifically designed for that purpose by neuropsychologists. This facilitates to track the visual gaze of a person on a screen, letting us to know what takes his/her attention and which are the reasons for distractions. In short, the system provides to the therapists with objective information, relevant from a clinical point of view, that helps to improve the process for diagnosing the attentional deficits of patients with Acquired Brain Injury (ABI). Furthermore, the system would be easily adapted to be used in other groups of patients or pathologies, such as schizophrenia, cognitive decline in older adults, or Attention Deficit Hyperactivity Disorder (ADHD) in childhood.
This solution consists of an eye-tracking device integrated with a software specifically designed by experts in neuropsychologists from the Institut Guttmann, for diagnosing attentional deficits.
The created software basically is based on a task that presents to the patient a set of screens with a couple of images. The patient has then to determine if the image is exactly the same or has any difference. The software includes an algorithm that automatically detect visual attention patterns, determining how the patient focuses his/her attention, which are the search strategies used, or what takes his/her attention. This information plus the number of correct answers, errors, and reaction time, provides to the neuropsychologist with objective information that helps to improve the diagnosing process, which will be in the end a key factor on the success of the treatment program designed for each patient.
