Exploring Plausibility and Presence in Mixed Reality Experiences
IEEE Transactions on Visualization and Computer Graphics
|April 7, 2023
Summary
This study explores how mixed reality (MR) affects user presence. Incongruencies in Augmented Reality (AR) and Virtual Reality (VR) impact plausibility and spatial presence differently based on sensory and cognitive processing.
Area of Science:
- Human-Computer Interaction
- Virtual Reality
- Augmented Reality
- Mixed Reality
Background:
- Mixed Reality (MR) applications span Milgram's Reality-Virtuality (RV) continuum.
- Recent theories explore constructs and factors defining MR experiences.
- Incongruencies across information processing layers can disrupt MR plausibility.
Purpose of the Study:
- Investigate the impact of incongruencies on different information processing layers (sensation/perception, cognition).
- Examine effects on spatial and overall presence in Virtual Reality (VR) and Augmented Reality (AR).
- Analyze how sensory and cognitive incongruences affect perceived plausibility and presence.
Main Methods:
- Developed a simulated maintenance application for virtual electrical devices.
- Employed a 2x2 between-subject design in VR (congruent sensation/perception) and AR (incongruent sensation/perception).
- Induced cognitive incongruence via absent power outage feedback, decoupling cause and effect.
Main Results:
- AR (incongruent sensation/perception) showed decreased plausibility and spatial presence compared to VR (congruent sensation/perception) in the congruent cognitive case.
- Conversely, both ratings increased in the incongruent cognitive case for AR versus VR.
- Significant differences observed in perceived plausibility and spatial presence ratings between VR and AR conditions.
Conclusions:
- Sensory and cognitive incongruences in MR have differential effects on user presence and plausibility.
- The interplay between information processing layers is crucial for designing immersive and believable MR experiences.
- Findings contribute to theories of MR experiences by detailing the impact of layered incongruencies.

01:21Gestalt Principles of Perception
362
Gestalt principles provide a framework for understanding how humans perceive objects as unified wholes within their context. These principles are essential in explaining the cognitive processes that make sense of complex visual stimuli by organizing them into coherent groups. One fundamental principle is proximity, which posits that objects located close to each other are perceived as a collective group. For instance, when dots are positioned near one another, the visual system interprets them...

01:12Modeling and Similitude
304
Scaled modeling is a fundamental technique in engineering, enabling the study of large and complex systems by creating smaller, manageable replicas that recreate critical characteristics of the original. In hydrology and civil infrastructure, for example, scaled models of dams help analyze water flow, turbulence, and pressure. This method allows for accurate predictions of real-world behavior within a controlled environment, significantly reducing the cost and time involved in full-scale...

01:15Depth Perception and Spatial Vision
776
Depth perception is the ability to perceive objects three-dimensionally. It relies on two types of cues: binocular and monocular. Binocular cues depend on the combination of images from both eyes and how the eyes work together. Since the eyes are in slightly different positions, each eye captures a slightly different image. This disparity between images, known as binocular disparity, helps the brain interpret depth. When the brain compares these images, it determines the distance to an object.

Nonconscious mimicry occurs when individuals alter their mannerisms to match the behaviors and expressions of those nearby, without intention.

01:08The Availability Heuristic
6.0K
A heuristic is a general problem-solving framework (Tversky & Kahneman, 1974). You can think of these as mental shortcuts that are used to solve problems. Different types of heuristics are used in different types of situations, and the impulse to use a heuristic occurs when one of five conditions is met (Pratkanis, 1989):

01:12Perceptual Constancy
474
Perceptual constancy is the ability to recognize that objects remain consistent and unchanged even when their appearance varies due to changes in sensory input. There are four main types of perceptual constancy: size constancy, shape constancy, color constancy, and brightness constancy.
Size constancy is the recognition that an object remains the same size, even when its image on the retina changes. For instance, a bus is perceived to be large enough to carry people, even if it looks tiny from...
