The basic idea of the proposal regarding the VR storytelling is, in addition to the difference in the angle that creates the stereoscopy effect, showing different contents on the two lenses of the headset (i.e., one lens is showing a cat while the other is showing a dog). However, as most of the people have never experienced seeing things completely different in two eyes, as discussed in the above section \ref{674635} (The State of Art in VR: Realism vs. Formalism), the story told by such two-eye technique will be difficult to be understood. To address the problem of the incomprehensible formalism in VR, and to continue the idea of adding a new understanding to the reality through VR, only some minor difference will be shown between the two eyes. As shown in Figure 1, the two pills have the identical shapes but the different colors. As most parts of the visual stay the same, the audience could still recognize what they see through the two-eye experiment as a pill. Then the paper is trying to figure out how the audience will perceive the little nuance that does not follow the realism.
Proposed Analysis
For each two-eye-experiment in VR, the user testing will be based on the questionnaire in two steps. Each experiment will be conducted in two trials with different groups of participants. For the first trial, a small group of participants will be shown with the VR experience and asked to write down what they think the nuance in two eyes represents. After that, all of the interpretations of the nuance will be collected and summarized into several options for people to choose. Then the second trial will start with a larger group of the participants, and the same two-eye experiment will be shown to them. In this time, instead of writing down their own interpretation, all of the testers will be asked to choose from the options summarized in the first trial. The result of the questionnaire will be collected for analyzing if there is a statistical significance in people's interpretation.
Implication
Due to the constraint of the apparatus, showing the VR content to people without the headset is always problematic. One of the commonly-used alternative methods is to show the 2D screen recording of the VR experience. However, when showing the screen recordings of the experiment introduced in the paper, people could not get a clear sense of what it looks like: the two-eye-experiment could only be experienced via VR headset. The further you make the VR experience away from realism, the harder people could feel it without the VR medium.
Conclusion & Discussion
It is something about the medium specificity of VR that goes beyond people's perception of reality. The world people live in is formed by looking at the surroundings from their eyes, while the world represented in VR could be perceived beyond the restriction of human eye. In this light, if separating virtual reality from the apparatus of the headset, it would be like a dream -- the mere illusion in people's mind regardless what they see when they are awake. Then why should such dream only exist in the form of the epistemology of human? Quoting from the film Inception (2010), "we mustn't be afraid to dream a little bigger."
