Position estimation with a low-cost Inertial Measurement Unit
This video demonstrates how the position can be extracted in real-time using only the Inertial Measurement Unit (IMU) inside the Oculus Rift. The Inertial Navigation System (INS) uses filtering in different stages of the double integration to correct drift. Only separate and marked steps are tracked with still some error. The person following the user is only for preventing the user to collide with walls.
The usability of this was tested showing that it highly reduces motion sickness (simulator sickness in virtual environments) when using the Oculus Rift, thus providing a solution with no extra-hardware required for locomotion. The video shows the different scenarios where the user had to walk.
