Students designed eye tracker testing rig

WSU engineering students are testing eye-tracking technology to improve the quality of life for people who have neurodegenerative diseases and no alternative way to communicate. Last semester, the team was building a testing rig to evaluate eye trackers for their Capstone project, said Jon Campbell, project mentor and senior research software development engineer at Microsoft Research. An eye tracker is a camera that recognizes a face and follows a person’s eyes to monitor where they are looking. Eye trackers are linked to a communication system or computer, but are not compatible with everyone, said Leif Harfst, WSU alumnus and former engineering student who worked on the project. For example, someone’s posture, skin color, eye color or movement characteristics may confuse the technology.

January 13, 2021 Looking like an extravagant Halloween decoration, the sophisticated robot, which has artificial eyes and a Jason-like facemask, is controlled by an X-box controller and uses simulated facial features to test the eye-tracking devices. When people are set to receive eye-tracking technology, they are facing devastating challenges: Neurodegenerative disease, such as amyotrophic lateral sclerosis (ALS), leads to progressive muscle weakness and paralysis. As patients lose their ability to speak, move a mouse, or express their thoughts, they and their families are often left bewildered and overwhelmed. Yet, the technology is not standardized and trying to customize it to the patient can be frustrating and exhausting, especially for the patient. The devices, which help patients perform a variety of functions, such as clicking and scrolling, have to track a person’s gaze perfectly in order to meet their users’ needs.
