BCI based hybrid interface for 3D object control in virtual reality

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.
