Eye-tracking

After developing hardware for computers and laptops for years, Sweden's Tobii Dynavox has now brought its eye-tracking know-how to Apple's iPad, giving a voice to folks with conditions like cerebral palsy, ALS and spinal cord injury.

A study is describing a biomarker to identify a person’s risk of developing anorexia nervosa. The research proposes measuring levels of anxiety alongside a type of twitching eye movement can identify those with, and at risk of developing, the disorder.

Although it's certainly best to start addressing autism as early as possible, the disorder is often difficult to detect in young children. A new iOS app has been designed to help, by tracking a child's eyes as they watch videos.

Eye tracking cameras and AI analysis can reveal your identity, gender, age, ethnicity, weight, personality traits, drug habits, emotions, skills, abilities, fears, interests, and sexual preferences, says a rather dystopian research review.

When tracking a sleeping person's eye movements, you typically have to stick hard-wired electrodes onto their face. Soon, however, an unobtrusive flexible mask could do the job – while also measuring their heart rate.

We've already seen electronic glasses that watch the wearer's diet and automatically change focus, among other things. An experimental new pair monitors the user's health, lets them control games, and switch to being sunglasses as needed.

For some time now, the tracking of eye movements has served as a means of assessing neurological health. A new system is said to do so more precisely than ever, providing highly accurate readings in just 10 seconds.

Video-camera-equipped glasses may show you what the wearer's head is pointing at, but they certainly don't indicate what the person's gaze is actually fixed upon. A new headset is designed to do just that, however, and it could be used to advance a number of technologies.

The US Food and Drug Administration (FDA) has delivered a Breakthrough Device Designation to a novel eye-tracking technology that claims to offer objective and early diagnosis of Parkinson’s disease. The FDA designation is hoped to accelerate the approval process for the test offering clinicians a new and reliable way to diagnose the degenerative disease at its earliest stage.

In the age of wearable computers, scientists in the laboratories of DARPA, Google, and universities around the world see contact lenses not as tools to improve our vision, but as opportunities to augment the human experience. But how? And why?

​We've seen it in movies many times before … the reluctant witness who looks right at the mug shot of the murderer, and falsely claims that they don't know him. Soon, however, police could know if such people are lying – by watching their eyes.

Presbyopia is a common form of age-induced far-sightedness. Now a Stanford team has developed a pair of high-tech specs called autofocals, which use fluid-filled lenses, depth-sensing cameras and eye-tracking technology to make sure whatever a wearer is looking at stays sharp.
