Project Background: Current Technology Eye trackers use light reflected off the eye to determine gaze position. The OEMI-7 replica eye is designed for both bright and dark pupil eye tracking and will be the eye used in our device. There is currently no formal consensus on how to measure and report data quality of eye tracking devices. This lack of standardization prevents the direct comparison of information gathered. Designers need to know what range of accuracy and precision they can expect from a system in order to design an interface which will operate properly. Manufacturers want to report, compare and optimize the quality of data their systems produce, and know that other manufacturers are using the same measures. 2/12/2015 P15051: Robotic Eye

Problem Statement Eye trackers are human interface devices used to observe and measure movement of the human eyes. There currently exists no standardized test method for evaluating the quality of the data collected by human eye tracking devices. This lack of a clear standard of testing creates unreliable and incomparable data for use in the many fields utilizing eye tracking devices. The goal of this project is to develop a robotic eye which can mimic the movement characteristics of the eye and provide a standardized environment for the quality assessment of existing eye tracking devices, free from any biological variance. The project will focus on creating a programmable robotic eye mount, capable of smooth pursuit as well as saccade, which can be used in conjunction with a variety of video-based eye tracking software. The project will seek to minimize the cost to manufacture, maintain, and operate such a device while maintaining high repeatability and ease of operation. 2/12/2015 P15051: Robotic Eye
