Abstract

One of the all time issues with Virtual Reality systems regardless if they are head-mounted or projection based is that they can only provide perspective correctness to one user. This limitation not only affects collaborative work which is nowadays the standard, but it has also been shown that not having a perspective correct views increases collaboration times. Different approaches have been presented throughout the past years for generating perspective correct images to several users. One of such approaches relies on bending the light to generate perspective correct images. Lenticular printing is a technique that uses the properties of small lenses called lenticules for bending the light and generate different images depending on the position a lens sheet is seen from. In this dissertation I am going to cover a general overview of the different parts of a VR system and the anatomy of lenticular lenses to get the reader familiarized with the content of this text. A state of the art of the different methods for multiplexing images from a single screen is also going to be presented. A lenticular lens simulator and the mathematical background that supports a prototype presented in this dissertation will be covered. Also, a hardware and software overview of a prototype that was built for multiplexing images through lenticular lenses and all the design considerations that need to be taken into account is going to be exposed. A result analysis of the different lenses assessed is also going to be introduced with a comparison between the different screen/lens combinations tested and finally a set of conclusions on the best parameters needed for a lenticular lens depending on the screen used are going to be shown with some considerations of future work that could be further looked into to enhance the findings in this dissertation.
