The next feature comes from Mind Maze VR, which uses EEG (ElectroEncephaloGraphy) sensors and depth cameras so it can support actual hand interactions to the virtual world.
Augmented Reality (AR) is another boon in VR where virtual objects are incorporated in the real world environment. Google explored this field with the Google glass. Although not much of a success due to the fact that it was considered intrusive for the public, the skepticism was later gone after the Oculus came to view. Then other AR headsets like the OSR Vision and the Leap Motion then came to light.
The next big leap came in the form of Microsoft's Hololens, where one can see the real world through its see-through lens and the virtual objects are embedded. The accuracy of the human eye cannot be matched with a digitized feed and Microsoft saw that well. It was an excellent option for the 'Mixed Reality' feel.
Current research challenges in Virtual Reality?
Let's look at some of the challenging tasks that are currently (July 2017) being tackled in this field of VR by researchers around the world:
- Using your own muscles in VR: VR currently has controllers that uses infrared technology and other means to be tracked in the virtual space. The actions are performed by the corresponding buttons in the controllers. The next step is to use the users own muscles to give the corresponding action, this time directly. Ideas are underway to use sensors attached to the muscles of the human body so a move in the arm will correspond to an arm in the VR world to move. This will increase the immersive experience in VR.
- Using force feedback: One of the challenges in VR is to 'feel' the world and not just see the world. One work includes computer controlled stilts that will change in response to the VR terrain. For example, if a person walks in the virtual world upstairs, then the real world will respond accordingly. This will give the feeling of reality to a whole new level. The haptic technology is advancing rapidly to give users the 'feeling' of being in the virtual world. Impacto is a product trying out this field, it is a device that provides haptic feedback based on the situation. It simulates muscles tactile sensitivity by giving the users a shock impact feeling upon a virtual stimulus. In simple words, if someone punches your arm in VR world, your gonna feel it in the real world! It won't be much force as to send you flying but a simple tap is all it takes to increase the immersive feeling of VR.
