Eye-writing Tech May Help People with Limiting Conditions Communicate Freely

Researchers at Université Pierre et Marie Curie in Paris have made a new discovery that may help people use eye movements to draw and write in cursive. The technology is described in a paper published recently in the online publication Current Biology.

“Contrary to the current belief, we show that one can gain complete, voluntary control over smooth pursuit eye movements. The discovery also provides a tool to use smooth pursuit eye movements as a pencil to draw, write, or generate a signature.”

According to the researchers, the eye-writing technology could make communication easier for people with Lou Gehrig’s disease or other conditions where arm and leg movement capabilities have been lost.

The technology may also help to improve eye movement for those with conditions such as ADHD or dyslexia, the researchers say. In addition, it could prove useful for helping surgeons or athletes to strengthen eye-based skills needed in such professions.

Paralyzed Artist Writes and Paints Again with Help from Open Source Community

When L.A. street artist Tony “Tempt One” Quan was diagnosed with ALS, the disease left him virtually paralyzed. It looked like he would never paint or write again.

What happened next, though, would be practically unbelievable if it were to take place within a work of art. The documentary that tells this story, however, has captivated the minds of all who’ve seen it.

Now, the story of how open-source technology has given Quan a second chance to create is also getting a second chance of sorts before being released more widely.

This film NEEDS to be seen by people.”

— The most common viewer comment after seeing the film

The documentary, Getting Up: The TEMPT ONE Story, which was the recipient of the 2012 Audience Award  at the Slamdance Film Festival, needs some technical upgrading before it is more widely released. The goal behind the project: “Our purpose is to inspire people to see that when a singular individual teams up with a like-minded community, the once impossible becomes possible.”

Cheaper Eye-Tracking Technology Could Support New Applications

Biomedical engineering researchers at the Public University of Navarre (UPNA) are developing a more affordable, more widely usable eye tracking device.

Such devices note where people are looking, and the technology has been used primarily to help people with disabilities (to interact with a computer cursor, for example) and to perform market research (to learn what consumers find attractive).

The idea behind our project is to come up with eye tracking at a low cost, and in such a way that the user can install the software in his or her device and use a webcam for the purpose, without needing additional illuminators or very expensive optical components.”

—Arantxa Villanueva-Larre, head project researcher, UPNA

New possibilities for using eye tracking include incorporating the technology into videogames or driving. For example, drivers whose eyes were not focused forward for a specified period might be alerted by eye-tracking software to pay attention to the road.
