Augmentation of Head Rotations
In this project we introduced the concept of augmented head rotations in head-mounted display (HMD) environments. The augmentation techniques are based on gains that scale virtual head rotations relative to the tracked physical rotations of the user's head. For instance, by increasing virtual pitch rotations, users can look down at their feet without having to assume an unnatural pose that otherwise would be necessary due to the limited field of view of today's HMDs. In this project we determined users' sensitivity to small manipulations of virtual head rotation angles, and determined ranges in which users can be manipulated without them being able to detect the manipulation.
