The conventional VR system from the day one relied on heavy expensive hardware that took a lot of space and was fixed at its place. In order words, VR was fixed on its place and the user had to reach there. The advancement in the field of HMD’s opened the first VR applications that could be brought to a remote user’s. Although the HMDs’ can facilitate mobility, it still requires special tracking sensors, a dedicated computer for calculation, expensive graphic cards and the HMD itself. Furthermore, a bundle of cables is always needed along with above equipment that can limit the movement space for the user.

A VR application inside smartphone does not necessarily need cables and can allow free user movement. The high end smartphones can handle computationally expensive application and can offer much more than the conventional usage e.g. navigation, taking pictures, small games etc. One limitation in smartphone VR is the lack of dedicated position tracking or user head tracking. Therefore, we have developed a solution for smartphone VR that achieves the position tracking using mobile phone camera. The below figure shows the hardware construction for smartphone VR.

The benefit of this implementation is the stand-alone use of smartphone as a device for rendering, visualisation and tracking.  This removes the need of unnecessary cables, dedicated graphic card and the tracking sensors. The interaction possibilities are being analysed and the demo videos of this application will follow shortly. 

Smartphone VR

In development:

  • In order to interact with virtual objects in the scene, controller have to be integrated in this application. Therefore we are looking for a 6DOF controller that can be user with various VR software and VR systems.
  • We are also working on upgrading SVR2GO platform to an interactive multi-user-system.
