Who will earn Eye-Tracking tomorrow?

Technology Eye-Tracking allows you to track the position of the user's eyes on the computer screen using one or more cameras. The first mentions of research in this direction refer to the beginning of the 20th century. Researchers with photographic film and glare on the eyeball tried to track the direction of the eye. Already at the end of the last century, this technology was used in the guidance systems of combat aircraft and helicopters. Currently, tracking a person’s gaze is effectively used to ensure the interaction of persons with disabilities with computers, as well as in various gaming applications. Even with the help of this technology, we study the usability of interfaces and the effectiveness of advertising. What else can this technology give and to whom?

The observed increase in the performance of mobile devices in the near future will give developers the opportunity to effectively solve eye-tracking tasks on tablets and smartphones. Already in 2013, Senseye plans to deliver its software for controlling the interface using a front-facing video camera to developers of mobile devices. Apple does not sleep either - a patent for a 3D Eye-tracking GUI . Undoubtedly, the implementation of this interesting technology and cool chips should appear in the near future.

However, a natural question arises - what else will this technology provide besides interfaces? I think the first consumers of "side" information of this technology will be advertisers. Where the user looks, what he reads, and what “runs over his eyes,” on which pictures he holds his eyes, how his facial expression changes. A huge amount of information for advertising and marketing research. Information you can easily monetize. What else will fall into the lens of a constantly turned on camcorder? The interior of your room, the facade of your house, everything can be used to target advertising. On the one hand, someone must finance the development of a new interesting technology. But I think that we will have to pay for it with another part of our personal life.

There are more issues related directly to security. Perhaps not the most effective, but still existing GrIDsure and PassFaes authentication technologies, in which the user must select the predefined fields on the picture displayed to him, simply lose their meaning.

I stopped on the issues that are called lying on the surface. But if eye-tracking technology becomes widespread, it will undoubtedly attract the attention of intruders. What else they can think of, in order to use eye-tracking for their own purposes, one can only guess.

As usual, the new technology carries new threats. I would like a more attentive attitude of developers to security and our privacy.
