Summary: The development of a compact and low-cost olfactory display for virtual reality systems has the potential to enhance the olfactory experience in virtual environments. Through user studies and gas sensor analysis, the researchers have shown the clear and consistent output of the device, as well as its intuitive usability and support for gameplay interaction. A virtual wine tasting game served as a demonstration of the device's capabilities in recreating an olfactory experience and facilitating training and gameplay interactions.

Summary: This study examined the effects of omega-3 supplementation on olfactory recovery in patients with postviral olfactory dysfunction. The results showed that the improvement in odor thresholds was more pronounced in the group receiving omega-3 supplementation compared to the control group. Age, sex, and duration of symptoms did not have an effect on olfactory scores in both groups.

Summary: The study aimed to determine the feasibility of a new handheld digital scent device (DSD) as an olfactory assessment test. The research found that the DSD test scores were higher than the 40-item Smell Identification Test (SIT-40), with strong correlation and high agreement between the two tests. Therefore, the DSD has the potential to be an effective tool for olfactory assessment testing.

Summary: To increase the integration and versatility of Olfactory Interfaces (OIs) in everyday scenarios, we present OlfacKit, a comprehensive pipeline that includes a user-friendly design tool for modeling OIs, an assembly workflow with kits and tutorials, and a WebUI for prototyping smell control. By testing atomization performance and conducting a workshop with 15 participants, we demonstrate the feasibility and usability of OlfacKit, generating creative ideas and implementing working prototypes. The detailed findings and insights offer implications for future OI design.

Summary: Smell is an important aspect of avian behavior and ecology, and evidence suggests that birds use odoriferous preen oil to minimize detection by nest predators and for intraspecific olfactory communication. While there is mixed evidence for seasonal and sex differences in preen oil, a systematic review found that seasonal differences were present in 95% of species and sex differences were present in 47% of species. Phylogenetic comparative analyses supported the olfactory crypsis hypothesis for ground-nesting species and suggested that sex differences were more likely in species with uniparental incubation and during breeding.

Summary: This study compared the effects of lemon and lavender scents on cognitive resource deployment during a virtual reality train journey. The findings indicated that subjects exposed to lavender scent required higher cognitive resources when processing information, while there was no difference in self-reported pleasantness and involvement between lemon and lavender conditions. The study revealed that lavender scent preserves the quality of customer experience as effectively as the more commonly used lemon scent.

Summary: In this paper, we present the design and development of a simple vortex-based olfactory display that effectively provides controlled release of odours with minimum amount required. The display consists of a steel tube with 3D-printed apertures and solenoid valve operation. User testing revealed that the time to identify an odour was not strongly related to concentration, but the intensity of the odour was correlated. Despite the wide variance in human panel results, the working olfactory display can be applicable to various application scenarios.

Summary: This study explored inflammatory endotypes in chronic rhinosinusitis using unsupervised cluster analysis of olfactory cleft biomarkers, identifying different inflammatory signatures and significant differences in olfactory measures across clusters. Organizing patients into clinically meaningful endotypes based solely on olfactory cleft biomarkers could help discriminate between patients with chronic rhinosinusitis and controls.

Summary: The study investigated the relationship between olfactory sulcus (OS) depth and olfactory function, considering age and gender. Normative data on OS depth were provided for a population with normal olfactory function. Results showed that the right OS was deeper than the left side in all age groups. Women had deeper OS on the left side compared to men. OS depth explained only minor portions of the variance in olfactory function, which was largely determined by age. Age-related normative data on OS depth were presented.

Summary: This study aimed to stratify perceptual characteristics and odors based on reduced sense of smell, to create olfactory experiences that can be enjoyed by both normosmic and hyposmic individuals. Results found that perceived intensity and familiarity with the odor were key discriminating characteristics between olfactory diagnoses, while evoked pain sensation and perceived temperature were not discriminating factors.

Summary: This study establishes a mapping for mid-air haptic experiences based on two user studies. By rating and verbalizing their experiences, participants identified five distinct stimuli and generated mappings for 17 sensations and 23 experiences related to these stimuli. This mapping provides guidance for designers and researchers working with mid-air haptic technologies.

Summary: Taste perception can be influenced by both the visual attributes of the environment and the shape of the food. Previous studies have focused mainly on non-edible shapes, making the effect of mouthfeel on taste perception unclear. Using virtual reality, this study explores the effects of colored virtual environments on taste perception of differently shaped food samples and finds that mouthfeel can influence sweetness perception and the lighting color in a virtual setting may dampen sweetness experiences.

Summary: Change blindness refers to the phenomenon where people fail to notice dramatic changes in their visual environment. In virtual reality, there are differences in the perception of changes in one's own virtual body compared to the body of another person. A study conducted in virtual reality showed that a majority of participants did not notice changes in their own face or the face of the virtual instructor. This suggests that people tend to make inferences about their visual surroundings without paying attention to details, and changes in one's own body may impact self-representation.

Summary: Mid-air buttons currently have slow and error-prone haptic feedback. Researchers have proposed an approach that extends haptic feedback to the whole hand, simulating the pull up effect when users activate buttons. The whole-hand feedback reduces button press duration and improves button activation compared to localized haptic feedback.
