Physical Space Performance Mapping for Lenticular Lenses in Multi-user VR Displays

This limitation increases collaboration times and reduces usability of such systems. Lenticular lenses have been previously used to separate users in multi-user VR systems. On this paper we present an assessment of the area of interaction of users in a multi-user VR system that uses lenticular lenses.

This limitation affects collaborative work which is the standard in any industry. Several approaches have been proposed to generate perspective correct images for different users but not only are they highly complex but also require lots of custom circuitry. On this paper we present the design, architecture and the mathematical background of an affordable optical routing multi user VR system that uses lenticular lenses for separating users and providing perspective correct images.

Such limitation affects collaborative work which is nowadays the standard anywhere. One of the approaches for generating different perspective correct images to several users is through optical routing. This approach relies on bending the light to generate perspective correct images to the engaged users. Lenticular lenses can bend the light to be able to generate perspective correct images for several users depending on their positions. On this paper we present an analysis that lets us understand the pixel spread correlation with lenticular lens efficiency on multi user VR displays.

This is a significant limitation that reduces the applicability of Virtual Reality approaches for most kinds of group collaborative work, which is becoming more and more important in many disciplines. Different approaches have been tried to present multiple images to different users at the same time, like optical barriers, optical filtering, optical routing, time multiplex, volumetric displays and lightfield displays among others. This paper describes, discusses and compares different approaches that have been developed and develop an evaluation approach to identify the most promising one for different usage scenarios.
