“…None of the participants reported changes in anxiety levels (indicating that the participants were conscious that the AR signal was an illusion), but skin conductance measurements told a different story, revealing signs of stress. Similarly, Nakano et al (2019) served ramen and somen noodles to a small group of experiment participants ( n = 18) who wore AR headsets that altered the visual appearance of the noodles so that ramen appeared to be somen and vice versa. All but three of the participants reported perceiving the flavor of what they were shown rather than what they were actually eating.…”

This article explores the democratic implications of the wide adoption of XR (eXtended Reality) technologies, drawing on Hannah Arendt’s political theory and her concept of common reality. Arendt argues that the intersubjective construction of a common reality is what enables the establishment of factual truth and that both are prerequisites for a functional democracy. Without them, ideology can be established as truth by anti-democratic forces with power over media outlets, paving a path toward totalitarianism. This article argues that XR technologies can be used to inhibit the construction of a common reality through the same individualization of media experiences that has been shown to impede democratic processes in the social media context. The companies generating increased revenue through individualized micro-segmentation are now also vying for dominance in the XR media arena. It is argued in this article that such individualization can impede the co-construction of a common reality and a factual truth because XR media are hyper-persuasive and capable of altering an individual’s overall perception of reality. The viability of such platform-controlled individualization in XR is demonstrated through an Arendt-based critique of four properties related to XR technologies: Hypertargeted personalization, false memory creation, reality indistinguishability, and predictive processing theory. Based on these analyses, the article concludes that XR policy and regulation must consider how XR gives platforms unprecedented persuasive powers as they become capable of altering a user’s reality perception remotely and how, per Arendt, this may threaten democracy.

“…The influence of optical visualization over the gustatory interface has been experimentally examined for correlation in 2019. The proposed system uses an image-to-image translation to modulate the appearance of the food being consumed in real-time by implementing a generative adversarial network (GAN) in an AR setup with a limited taste modulating resultant effect observed upon the completion of the experiment [18]. It was initially termed 'Deep Taste' [19].…”

Digital Taste in Mulsemedia Augmented Reality: Perspective on Developments and Challenges

Digitalization of human taste has been on the back burners of multi-sensory media until the beginning of the decade, with audio, video, and haptic input/output(I/O) taking over as the major sensory mechanisms. This article reviews the consolidated literature on augmented reality (AR) in the modulation and stimulation of the sensation of taste in humans using low-amplitude electrical signals. Describing multiple factors that combine to produce a single taste, various techniques to stimulate/modulate taste artificially are described. The article explores techniques from prominent research pools with an inclination towards taste modulation. The goal is to seamlessly integrate gustatory augmentation into the commercial market. It highlights core benefits and limitations and proposes feasible extensions to the already established technological architecture for taste stimulation and modulation, namely, from the Internet of Things, artificial intelligence, and machine learning. Past research on taste has had a more software-oriented approach, with a few trends getting exceptions presented as taste modulation hardware. Using modern technological extensions, the medium of taste has the potential to merge with audio and video data streams as a viable multichannel medium for the transfer of sensory information.

“…These techniques modulate the taste and satiety by modifying the appearance of the food that the person is about to eat, such as its texture and size. There have also been reports of attempts to change the appearance of food in order to present the sensation of eating something different from what someone is actually eating [11]. These attempts require information on the location of the target food, which is conventionally detected using image processing by creating the right environment for image detection.…”

Edible Retroreflector Made of Candy

Recently, methods of projecting images onto food using a projector have been the subject of various studies because they have the potential to intervene in the visual appreciation of food, and also because such technology has the potential to create new production methods and services related to food. Since projection can be achieved easily using an optical marker, an edible retroreflector made of agar has been proposed; however, an agar retroreflector had the drawback of a short lifetime. In this paper, we propose an edible retroreflector made of candy, which is resistant to drying and can be used for a long time. Two types of retroreflectors, one with single layer and the other with two layers, were proposed and fabricated. The evaluation experiments showed that the proposed retroreflectors had sufficient reflection coefficient R of up to 84.76 for the single-layered prototype and up to 173.05 for the two-layered prototype. These coefficients are comparable to the coefficient 70 of commercially available glass-bead-type retroreflectors, which are strong enough to be used as markers for a camera. The prototype was also able to maintain its functionality for 10 days from the fixed-point observation. Furthermore, dynamic projection mapping on a pancake and motion capture were successfully demonstrated to show the potential applications.INDEX TERMS Candy, edible, food, optical marker and retroreflector.
