“…Various types of images are used as follows: Internet photos [13], X-ray images [8,24], image sets actively [25,26], streaming image sequences from surveillance cameras [27], multi-view cameras [6,[28][29][30], and RGB-D cameras [31,32]. One could store a sufficient number of viewpoints when one carefully captures a scene during enough time [13,25,26].…”

“…However, one will suffer from the geometric or photometric differences between the real and virtual scenes in the DR results due to the intervals between the preliminary observation and the current DR experience. In the case of real-time observation that can handle dynamic backgrounds [6,27,[29][30][31][32], because the number of installed cameras is physically limited, the number of viewpoints is sometimes insufficient. In addition, temporal inconsistency occurs when camera synchronization is not performed properly.…”

“…Thus, Meerits and Saito used an RGB-D observer camera for fast 3D reconstruction of hidden backgrounds as 3D polygon mesh in real time [31]. Ienaga et al reported an example implementation of a multiple RGB-D camera system to remove the viewer's body in an AR-based mirror system to improve the efficiency of teaching anatomy [32].…”

In this paper, we review diminished reality (DR) studies that visually remove, hide, and see through real objects from the real world. We systematically analyze and classify publications and present a technology map as a reference for future research. We also discuss future directions, including multimodal diminished reality. We believe that this paper will be useful mainly for students who are interested in DR, beginning DR researchers, and teachers who introduce DR in their classes.

“…In this context, we also think that the upcoming Apple Vision Pro will push the limits in DR, because it is a video-see-through device that can enable DR to reach its full potential [17]. In fact, the Digital Crown hardware of the Apple Vision Pro, which also exists for the Apple Watch, should enable us to seamlessly walk along the whole RV continuum (back and forth) and bring medical DR applications to reality, which are still almost nonexistent currently [18]. A potential example of the photo-editing capabilities of newer cell phones as a diminution operation is shown in Figure 2 [15].…”

The concept of reality-virtuality (RV) continuum was introduced by Paul Milgram and Fumio Kishino in 1994. It describes a spectrum that ranges from a purely physical reality (the real world) to a purely virtual reality (a completely computer-generated environment), with various degrees of mixed reality in between. This continuum is “realized” by different types of displays to encompass different levels of immersion and interaction, allowing for the classification of different types of environments and experiences. What is often overlooked in this concept is the act of diminishing real objects (or persons, animals, etc) from the reality, that is, a diminution, rather than augmenting it, that is, an augmentation. Hence, we want to propose in this contribution an update or modification of the RV continuum where the diminished reality aspect is more prominent. We hope this will help users, especially those who are new to the field, to get a better understanding of the entire extended reality (XR) topic, as well as assist in the decision-making for hardware (devices) and software or algorithms that are needed for new diminished reality applications. However, we also propose another, more sophisticated directional and layer-based taxonomy for the RV continuum that we believe goes beyond the mediated and multimediated realities. Furthermore, we initiate the question of whether the RV continuum truly ends on one side with physical reality.

“…Future generations of smart glasses are likely to be able to identify specific unwanted elements and remove them from our visual surroundings. Examples of possible uses include the removal of any non-essential objects, background colours, and so forth from the driver's vision in cars [28], the removal of irrelevant body parts in anatomy teaching to increase the learning effect [29]; and real-time, real-life ad-blockers [30]. Other similar technologies aim to change the user´s perspective rather than removing objects.…”

In this paper we propose a reduced reality concept of less-is-more that VR designers can use to create technological frameworks that reduce sensory overload and allow for better concentration and focus, less stress, and novel scenarios. We question the approach taken by scholars in the field of XR research, where the focus is typically to design and use technology that adds sensory information to the user's perceptual field and we address some of the confusion related to the typical uses of the term reality. To address the latter terminological muddle, we define reality as our conscious experience of the environment as emergent perception and we use this definition as the basis for a discussion of the role of sound in balancing sensory information and in the construction of a less cluttered and less stressful perceptual environments.
