While extensive research has focused on the flavor of Fu brick tea (FBT), the perceptual interactions among its aromatic components remain unclear. To address this, twenty representative aroma compounds were selected from FBT to determine their thresholds and evaluate their interactions by analyzing threshold changes before and after mixing. The results revealed discrepancies between the determined thresholds and literature values, particularly for -terpineol, methyl heptenone, and geranylacetone, which demonstrated ratios of 73.54, 6.62, and 6.41, respectively. Mixtures with similar aromas or structures exhibited synergy, whereas those with differing aromas or structures displayed masking effects. Additionally, the odor compound ()-nerolidol was added to the tea infusion at a concentration below its threshold level to investigate its impact on the overall aroma perception of FBT through sensory analysis and electronic nose assessments. The findings indicated that sub-threshold compounds could significantly influence the overall aroma profile of FBT.

VR Whispering: A Multisensory Approach for Private Conversations in Social Virtual Reality.
IEEE Trans Vis Comput Graph
March 2025
Private conversations in social Virtual Reality (VR) environments lack the nuanced cues of physical interactions, potentially diminishing the sense of privacy and social presence. This paper introduces Whisper, a novel multisensory interaction technique designed to enhance private conversations for social VR applications. We first conducted a formative study (N = 20) to understand private conversation demands, limitations of existing methods, and user expectations in social VR.

Change detection (CD) is critical in everyday tasks. While current algorithmic approaches for CD are improving, they remain imprecise, often requiring human intervention. Cognitive science research focuses on understanding CD mechanisms, especially through change blindness studies.

A broad spectrum of research is reviewed ranging from studies that have examined the mechanisms involved in thermal intensification and tactile masking, to more applied work that has focused on implementing thermal-tactile illusions such as thermal referral and illusory wetness in VR environments. Research on these tactile-thermal illusions has identified the differences between the senses of cold and warmth in terms of their effects on the perception of object properties and the prevalence of the perceptual experiences elicited.

Previous work has demonstrated that image-computable neural networks trained to differentiate natural shadow and occlusion edges exhibited sensitivity to boundary sharpness and texture differences. Although these models showed a strong correlation with human performance on an edge classification task, this previous study did not directly investigate whether humans actually make use of boundary sharpness and texture cues when classifying edges as shadows or occlusions.
