With the spread of virtual reality, eye tracker embedded VR headset gradually becomes a trend. A company such as Fove has already released its eye-tracking VR headset. However, the relatively low frame rate of eye tracker in VR HMD (e.g. 90 fps) makes tracking unstable with consumption of computing power. Understanding relations between gaze direction and head direction would be helpful, for example, to predict and compensate eye tracking with head tracking. In this research, a unity project consisted of a moving object with variable parameters was created to examine if there’s correlation exists between players’ head direction and gaze direction in eye’s smooth pursuit movement. Furthermore, object parameters, shape, color, distance, speed and horizontal moving degree were tested to explore whether they can elicit statistically significant differences in gaze prediction. Results revealed that while smoothly pursuing a moving object with the gaze, people’s horizontal and vertical component of head direction and gaze direction are separately linearly correlated. Moreover, formulas were calculated via linear regression to express their relations. As for object parameters, significant impacts were detected for all five parameters and interaction effect of speed and horizontal moving degree with various effect size, partial eta squared. ; Med spridningen av den virtuella verkligheten blir Eye Tracking-inbyggd VR-headset gradvis en trend. Ett företag som Fove har redan släppt sitt Eye Tracking VR-headset. Emellertid gör den relativt låga bildhastigheten för ögonspårare i VR HMD (t.ex. 90 fps) spårning ostabil med förbrukning av datorkraft. Att förstå relationer mellan blickriktning och huvudriktning skulle vara till hjälp, till exempel för att förutsäga och kompensera ögonspårning med huvudspårning. I den här undersökningen, var ett Unity-projekt bestående av ett rörligt objekt med varierande parametrar skapad för att undersöka om det finns korrelation mellan spelarens huvudriktning och blickriktning i ögonens ...
