Ruth and I went to Tampa last Monday to the University of South Florida where I was tested on five eye-tracking computers to find the one most compatible. Our appointment was for 10 AM and we left at 4:30 PM. It was a great experience. Two doctoral candidates and three graduate students spent the day with us.
I was given a battery of cognitive and word comprehension tests in the morning and the afternoon was spent with the computers.
My bifocal glasses and glare on the lenses threw three of the computers into a tizzy before we narrowed it down to one computer brand. Now we have to wait for Medicare approval. Please pray that I will be approved.
Eye trackers use a video camera that observes our eyes and produce high-resolution images of our irises and pupils and identifies the eye’s gaze points. On the computer screen is a keyboard. When the eyes fixate on a particular letter on the keyboard, the computer reacts much as a touch keyboard. By use of the eyes words can be formed for either voice emission or to create emails, blogs, or other documents.
Eye tracking will soon be available for a host of applications: as a peripheral device, an eye tracker can be added to a regular computer screen, it can be built into glasses or other wearable devices, and of course, specially designed computers with built-in eye tracking,
As far back as 2013 Popular Mechanics listed eye gaze as an emerging technology that will change our lives. Recently Google and Facebook acquired eye tracking start ups. Apple has acquired several eye tracker patents and some are predicting the upcoming iPhone 7 will have some type of eye tracking capability.
The learning curve for me will be steep, but those who have mastered it say that it is comparable to a touch keyboard in speed and accuracy.
