A world leader in eye tracking technology and non-invasive neuro-otologic diagnostic testing, was at a software version cross roads. The software of their system was written in an obsolete language, and needed to be redeveloped “from the ground up”. IRIS was hired to perform the backbone of this task. We developed the core software, and user interface for testing and analysis, including motion control, eye tracking (image and EOG), and laser motion. The system featured real time data acquisition of the patient’s eyes (X,Y,angle, pupil), digital and analog I/O, sensor feedback from chair and LASER motion (multi Axis). Development covered over 20 tests, and many system platforms. Since the initial engagement, IRIS has acted as expert consultants to solve critical objectives.
