Amplifying Realities: Gradual and Seamless Scaling of Visual and Auditory Stimuli in Extended Reality

Existing literature in the field of extended reality has demonstrated that visual/auditory manipulations can change a person's perception and behavior. For example, a mismatch between the physical self and the virtual self can have psychological and behavioral implications. There are many different approaches that can incur a perceptual change. An under-explored field of research are gradual and subtle manipulations, such as scaling the food one eats or scaling the heads of people one sees. In this position paper, I provide an overview of my prior PhD research focusing on means to gradually and seamlessly scale visual and auditory stimuli in extended reality, and investigations of the corresponding changes in human perception.
