“Design and Implementation of a Human Computer Interface Tracking System based on Multiple Eye Features”

Accessibility and inclusion have become new buzz-words in HCI. As practitioners in HCI, we are ethically challenged to keep accessibility in mind because we have varying assistive technologies that are common and available to us to use to help those with disabilities that promote further inclusion. Human eyesight is one of mankind’s most major senses. The eye is different from the other body parts that make up the human’s sensor array. A person’s eyes convey a great deal of information with regards to the meaning behind certain facial expressions. Also, the direction in which an individual is looking shows where his or her attention is focused. By tracking the position of the irises, useful interfaces can be developed that allow the user to control and manipulate devices in a more natural manner (Azam, S., Khan, A., Khival, M., 2009). Pupil tracking also has limitless possibilities outside of becoming a valuable assistive technology for those who are disabled and for those that are not disabled. Pupil tracking can be used in medical, educational, military, entertainment, and other applications.

What I like the most about pupil tracking is that it may allow for greater cognitive control during situations of stress and heavy multi-tasking where the speed of the human mind can work in an integrated fashion with speedy technologies, illuminating the slower response time from using a mouse or other slower input devices. This may also reduce errors as well.
