Poster: Sliding Viewport for Head Mounted Displays in Interactive Environments

The ability to manipulate objects is fundamental to most virtual reality (VR) applications. A multitude of metaphors have been developed to facilitate object selection and manipulation, including the virtual hand metaphor, which remains by far the most popular technique in this category. The utility of the virtual hand depends on the user´s ability to see it. Unfortunately, ensuring this is not always easy, especially in immersive systems which employ head mounted displays (HMD) with limited field of view (FOV), typically ranging from 40 to 60 degrees diagonally.
