Abstract— People attempts to apply the virtual reality (VR)
technology in various fields recently, however, there are many
limitations to apply the VR technology in existing interfaces in
various fields such as 3D object control. To solve this problem, we
propose a combination of eye-tracking and BCI technique to
control 3D objects in a three-dimensional VR as an alternative
interface. In our proposed interface, users select a virtual 3D
object in VR by eye-gazing which is detect by the eye-tracking
module of the system and manipulate the object by concentrating
their mind via the BCI module. To evaluate the performance of
our system, subjects perform the same experiments using the
proposed system comparing to other existing interfaces. The
result shows that the proposed interface has similar or better
performance than other interfaces. This result suggests that our
proposed interface can be used as an alternative interface of VR.
