The Fundació Miquel Valls, through its Support Product Bank, offers this device that allows people to use their computer with total autonomy.

SMARTNAV4 is the fourth generation of a mouse that helps people with amyotrophic lateral sclerosis (ALS) and other mobility-impairing diseases to use a computer. With the help of the integrated Dwell Clicking software, and a free on-screen keyboard created by Lake Software, THE SMARTNAV4 works by means of a small sticker made of reflectant material placed anywhere on the face and a sensor located on the screen. The user can control the mouse pointer on the screen with head movements in totally hands-free fashion. People with ALS can therefore write emails, answer text messages and do anything on the computer totally independently.
