A new technology called Senseye can track eye movements, allowing users to have a completely hands-free experience with their Android devices. Using a front-facing camera and infrared LED, Senseye can:
- Dim the screen when it notices that no one is watching it
- Scroll pages by tracking eye movements.
- Enter passwords by tracking eye movements across numbers.
- Shoot video game enemies also by tracking eye movements across a video game screen.
- Allow advertisers to track how long users look at various elements on the screen.
Perhaps best of all, Senseye is cheap to manufacture – the company claims the total cost of camera and LED is around $5 – which means it'll be far more likely to see wide-implementation than many of the experimental technologies we write about on this site. The company claims the first Senseye-enabled devices will ship in 2013, although Senseye isn't naming names yet.
