Evaluating orientations to Virtual Reality interfaces using Eye Tracking

In this paper, two interfaces,'90*4' and '180*2' were compared for surveillance live 360-degree video feed by performance in the spatial task. The performance was assessed during active navigation in a virtual environment. The virtual environment was simulated using game engine Unity with eye tracker integrated to it. The spatial task consisted of target search, and the target in our study was a cube. Gender differences were also addressed by response time in both interfaces. Along with this, eye movements were recorded through eye tracker to compare search patterns. The result suggested 1) High performer had more response time in both interfaces, 2) females showed a quicker response in target detection in both interfaces, 3) target detection in both interfaces were almost similar. 4)Mean fixation and fixation frequency were more for a high performer. This work provides insight into biological differences in low and high performer as well as on the gender differences while navigating and performing the task in these two type of interface. The future application can be, but not limited to, in designing interfaces, while considering gender and eye movements, for live 360-degree video feed surveillance system
