Cognitive Ability Evaluation using Virtual Reality and Eye Tracking

This work aims to create a virtual reality (VR) representation of Ravens progressive matrices (RPM) and apply available eye tracking (ET) technology to determine where the test person's eye gaze is located during the test. RPM are developed to evaluate abstract reasoning and there is a possibility to further understand the mental processes of the test person by adding ET. The result of this project is a test scenario where the user completes ten tasks from RPM in a VR environment. Reports containing heat maps and trajectories describing the eye gaze together with times and results of the tasks are automatically generated after the test has been completed. This extended information which is automatically gathered is meant to further expand the toolbox that psychologists use when performing psychological testing and might aid them in improving the accuracy of the results obtained from these tests.
