Minimising the duration of a system-controlled virtual reality tour

The duration of a virtual reality tour can be a crucial factor in affecting user experience. Lengthy exposure to a virtual environment can cause severe health issues similar to motion sickness, and wearing the Head-Mounted Display for a long duration can make the user fatigued. Minimising the duration of VR exposure can always help in addressing these issues. In this work, we have proposed an approach to minimise the duration of a system-controlled virtual tour by optimising the path connecting all the sites of the virtual environment. To optimise the duration, we theoretically compute the optimal time and the path to cover all the places of a virtual environment by reducing the problem to the famous Vehicle Routing Problem (VRP). Following our approach, we have also created a VR tour for the largest river island in the world, Majuli (Assam, India).
