Summary: This article reviews the literature on augmented reality (AR) in modulating and stimulating the sensation of taste in humans using low-amplitude electrical signals. Various techniques for artificially stimulating/modulating taste are described, with an inclination towards taste modulation. The article highlights the core benefits and limitations of taste augmentation and proposes feasible extensions using emerging technologies for taste stimulation and modulation.

Summary: The study focuses on a new method of GTS that can induce taste sensations at specific locations inside the buccal cavity using electrodes attached around the head. This novel configuration can manipulate the electrical potential distribution in the tongue and control the position where the sensation of taste is induced. This is the first report to achieve induction of spatially selective taste sensations at a specific position in the buccal cavity.

Summary: The demand for low-salt foods is increasing due to their health benefits. It has been discovered that edible fungi contain a large amount of umami components, which can enhance the salty taste of NaCl. The Antler fungus was found to have the highest umami intensity, and its enzymatic hydrolysate could effectively enhance the salty taste of NaCl at lower concentrations. This synergistic effect between umami and salty suggests that Antler fungus could be used as an ingredient in low-salt foods.

Summary: This study investigates the impact of the meningeal layers on the cortical electric field in transcranial electrical stimulation (TES) and transcranial magnetic stimulation (TMS). The results show that the presence of the meninges significantly increases the maximum electric fields in the cortex during TES, while the effect on TMS electric fields is minor. The findings provide a quantitative understanding of the influence of the meninges on TES and TMS and can contribute to the development of more accurate brain stimulation models.

Summary: This study aimed to investigate the effects of noisy galvanic vestibular stimulation (nGVS) on healthy and bilateral vestibular hypofunction (BVH) participants in different walking conditions. The results showed that nGVS effectively reduced walking deviations for BVH patients in light conditions and decreased lateral deviation for both healthy and BVH participants in dark conditions. The C/P ratio significantly decreased for BVH participants during 2 Hz head yaw walking in light conditions.

Summary: This study designed and investigated a stimulation waveform suitable for enhancing saltiness of low-sodium foods. The proposed waveform showed a saltier enhancement than existing waveforms, and it can present a saltiness equivalent to that of ordinary foods with a 30% reduction in salt content. Furthermore, the discomfort caused by electrical stimulation was not severe enough to be a problem for most participants. The study also qualitatively analyzed the changes in saltiness intensity and flavor of low-sodium miso soup.

Summary: This study conducted a systematic review on the application of transcranial direct current stimulation (tDCS) in patients with epilepsy, and the results indicate that cathodal tDCS may be a safe and effective technique for seizure control in patients with drug-resistant epilepsy. However, more and larger sham-controlled randomized trials are needed to further advance this treatment method.

Summary: Contrary to the conventional belief that galvanic vestibular stimulation (GVS) affects only axons, this study suggests that hair cells are also likely affected by this stimulation paradigm. Through computational modeling, it was found that GVS affecting hair cell vesicle release and axonal excitability simultaneously matched all experimental observations.

Summary: The odor-taste interaction is an effective method for salt reduction, where odorants associated with saltiness in soy sauce were identified and found to enhance saltiness and umami taste. These odorants, when added to food, significantly enhanced the perception of saltiness, indicating their potential use in compensating for reduced sodium chloride content in food.

Summary: Since the COVID-19 pandemic, travel and cooperation among engineers have been restricted. Telepresence technology could be used to reduce travel by allowing engineers to participate in work groups remotely. However, few telepresence systems have been widely implemented, possibly due to their complexity. This study proposes a system that uses a video chat application and a spherical camera to view a remote location on a laptop computer screen, making it easier for engineers to understand virtual space.

Summary: Transcutaneous electrical nerve stimulation (TENS) is a technique that can evoke tactile sensation on the hand without interrupting the interaction between the hand and environment. It has been mostly explored for restoring sensory feedback in amputees, but it can also be applied to non-disabled individuals to solve issues faced by tactile interfaces. We propose TENS at the wrist with multi-electrode targeting the cutaneous nerve bundles as a method to induce tactile sensation with higher spacial resolution.

Summary: Walking is a human need, and virtual reality can provide opportunities for virtual walking or travel. This study found that foot vibrations and scene congruency can enhance virtual walking sensations and ground material perception. Congruent vibrations were more effective than incongruent vibrations for walking-related sensations and telepresence.

Summary: The study found that a full-body avatar with a first-person perspective can enhance the sensations of walking, leg action, and telepresence, while a third-person perspective may weaken the sensations of self-motion and telepresence. Additionally, foot vibrations simulating footsteps can enhance sensations of self-motion, walking, leg action, and telepresence regardless of the avatar condition.
