With the recent explosion of popularity of virtual and mixed reality, an important question has arisen: “Is there a way to create a better blend of real and virtual worlds in a mixed reality experience?” This research attempts to determine whether a visual filter can be created and applied to virtual objects to better convince the brain into interpreting a composite of virtual and real views as one seamless view. The method devised in this thesis is being called 'Diminished Virtual Reality'. The results found in this study show that when presented with a scene composed of a combination of visually similar stimuli where one is virtual and the rest are not, participants of the study could not reliably identify whether all objects were real or if some of the objects were virtual after being exposed to the stimulus for 300ms. The “eccentricity effect” is an effect observed by Carrasco et al. [1] which describes the phenomenon where visual search tends to be better (faster and more accurate) when the target object is more central to the fovea and worsens as optical eccentricity increases. This effect was not present in the data from this study as a pronounced effect. The proposed factors that contributed to these results and the development of a 'Diminished Virtual Reality' shader are further outlined and discussed in this thesis.
