The Eye Tribe announced The Eye Tracker for Mac OS X, the first eye tracker and SDK [software development kit] for the operating system, at this week's Consumer Electronics Show in Las Vegas. It's eye-tracking software that enables people to interact with technology just by looking at it.

Previously only available for Windows-based computers and tablets, the US$99 software is targeted at developers. The SDK allows for integration into applications and games for tablets, laptops and computers — and eventually smartphones.

The Eye Tribe software enables eye control on mobile devices and computers, allowing hands-free control of websites and apps, eye-activated login, enhanced gaming experiences, and cloud-based user engagement analytics, says Sune Alstrup Johansen, CEO and co-founder of The Eye Tribe. With the Tracker, users can manipulate their device purely with eye movement, or with a combination of eye tracking and other inputs like touch, responding to natural eye movements as users interact with their devices.

The Mac OS X launch follows The Eye Tribe's competition in the inaugural TechCrunch Hardware Battlefield at the 2014 Consumer Electronics Show (CES). Alongside leading hardware startups from 11 countries, The Eye Tribe presented its technology, vision and business model to a diverse audience. Recently, The Eye Tribe began shipping pre-orders of The Eye Tribe Trackers, and launched its Developer Site and Developer Forum, where developers can share applications for Trackers and interact with The Eye Tribe team.

This announcement comes on the heels of raising another US$1 million in seed funding, primarily from existing investors, board members and key individuals in the US, including former semiconductor executive Richard Sanquini. For more info go to www.theeyetribe.com .
