Abstract

The vergence oculomotor system is used in viewing objects moving in depth, such as when a baseball player tracks a ball moving towards him. Based on the Dual Mode Theory it is composed of two components; a fast preprogrammed initiating component and a slow feedback-controlled sustaining component. The initiating component is described using open-loop control and the sustaining component is described as a closed-loop feedback control system. Previously, several languages have been utilized to develop programs to study and isolate the open-loop portion of vergence eye movements. Presenting a subject with a stimulus, which repetitively provokes an open-loop response, has been speculated to cause stronger adaptation in the vergence system. This study utilizes Lab VIEW 6i in developing a program capable of real-time experimentation to study the open-loop portion of vergence eye movements. Lab VIEW offers many options to the programmer and operator with a user-friendly interface for program development as well as an open architecture, allowing flexibility for future studies. This research validated that LabVIEW can be used for open-loop experimentation through a comparison proving that responses obtained from this code are similar to data published in the literature.
